Based on the quantified assessment result, the potential of the current geospatial transformation is evaluated. Its quantified assessment method realizes automatic assessment and no longer completely relies on manual assessment, thus improving the efficiency of geospatial transformation assessment.

[0040] Among them, before performing the operation of step S1100, obtaining the geospatial information of the current area to be evaluated, there is also a step of determining the current area to be evaluated. Among them, the current area to be evaluated is determined by checking on the map. Specifically, when determining the area to be evaluated, first obtain the map, and check the area to be evaluated on the map to determine the current area to be evaluated.

[0041] After determining the current area to be evaluated, perform the operation of step S1100, obtaining the geospatial information of the current area to be evaluated. When obtaining the geospatial information of the current area to be evaluated, it is obtained according to the local projection coordinate system. Among them, the geospatial information refers to the geographical location information of the current area to be evaluated. It should be noted that obtaining the geographical location information of the current area to be evaluated according to the projection coordinate system is common knowledge in the art and will not be elaborated here.

[0042] After obtaining the geospatial information of the current area to be evaluated, perform the operation of step S1200, extracting the assessment factors for evaluation from the geospatial information. Among them, the assessment factors include at least one of geospatial attributes and attribute values. Specifically, referring to Table 1, the geospatial attribute refers to the geographical attribute of the current area to be evaluated, including at least one of safety, site type, pavement status, lighting conditions, risk factors in the site, scale, site accessibility, and existing facilities in the area to be evaluated.

[0043] The attribute values refer to various possibilities included under each attribute. For example, for the attribute of safety, its attribute values may include at least one of: no hazard source, community entrance, garage entrance, ground parking lot, non-motor vehicle parking lot. For the attribute of site type, its attribute values may include at least one of: community central green space / square, front yard space, community sports activity venue, parking lot, other passage spaces. For the attribute of current paving status, its attribute values correspondingly include at least one of: only grassland, trees, shrubs and grass, both existing greenery and hard paving, only hard paving, unmanaged wasteland, others. For the attribute of lighting condition, its attribute values may include at least one of: located on the south side of the building, good lighting, located on the north side of the building, poor lighting, located on the east / west side of the building, average lighting, independent plot, no building obstruction. For the attribute of risk factors within the site, its attribute values may include at least one of: thorny plants / poisonous plants, height difference, uneven ground, blocked vision, no monitoring, no danger.

For the attribute of current facilities within the area to be evaluated, its corresponding attribute values may include at least one of: fitness facilities, sports activity venues, entertainment facilities (such as chess tables), no facilities, others.

[0047]

[0048] Here, it should be noted that when extracting the above-mentioned various evaluation factors from the geospatial information, it can be directly achieved by exporting the spatial evaluation form.

[0049] That is, based on the geospatial information of the area to be evaluated determined above, a spatial evaluation form (as shown in Table 2) is pre-constructed according to the determined evaluation factors. Thus, when performing step S1200 and extracting the evaluation factors for evaluation from the geospatial information, the spatial evaluation form can be directly pushed to the user.

[0050] Among them, the space evaluation form includes the attributes, attribute weights, attribute values of the current area to be evaluated, and the assignments corresponding to each attribute value. After pushing the space evaluation form to the user, step S1300 can be executed to score the evaluation factors according to the pre-established scoring rules to obtain a scoring result.

[0051] Here, it should be noted that for each attribute weight in the space evaluation form and the assignment corresponding to the attribute value, it can be filled in directly by the user or generated automatically. At the same time, for the attribute weight and the assignment of each attribute value, there is an assignment standard set in this application, and when filled in directly by the user or generated automatically by the system, the assignment is made according to this assignment standard.

[0052] Specifically, the assignment standard includes two types: the attribute weight assignment rule and the attribute value assignment rule. Among them, the attribute weight assignment rule includes: scoring according to the pre-established order of attribute importance, and scoring with a scoring ratio of 100% during scoring, that is, the sum of all attribute scores is 100% (i.e., 1).

[0053] Among them, the pre-established order of attribute importance is formulated according to at least one consideration factor among safety, operability of transformation, current advantages and disadvantages of the area to be evaluated.

[0054] In a possible implementation manner, when formulating the order of attribute importance, four factors including safety, operability of transformation, current advantages and disadvantages of the area to be evaluated are considered. Specifically, when formulating the order of attribute importance, the safety factor is given priority, followed by the operability of transformation factor, and finally the current advantages and disadvantages of the area to be evaluated. The finally obtained order of attribute importance can be determined as: safety, site type, scale > paving status > hazards in the site, site accessibility, and current facilities in the open space.

[0055] The attribute value assignment rule is: scoring according to the pre-established order of attribute value importance, and when scoring, the score is in a ten-point system, with a full score of 10 points and a minimum score of 0 points. That is, the highest score for each attribute value is 10 points and the lowest score is 0 points.

[0056] Among them, the pre-established order of attribute value importance is determined according to the consideration factors of its corresponding attribute. That is, the pre-established order of importance of at least one corresponding attribute value among the attributes of safety, site type, paving status, lighting conditions, hazards in the site, scale, site accessibility, and current facilities in the area to be evaluated is determined.

[0057] In a possible implementation manner, the importance order of the corresponding attribute values of safety, site type, pavement status, lighting conditions, risk factors within the site, scale, site accessibility, and the attributes of the existing facilities within the area to be evaluated is formulated in advance.

[0058] Among them, when formulating the importance order of the corresponding attribute values of the safety attribute in advance, the safety attribute determines the importance order of the corresponding attribute values according to the impacts brought by motor vehicles and non-motor vehicles to the current area to be evaluated. Specifically, when determining the importance order of the corresponding attribute values of the safety attribute, based on the fact that the danger level of motor vehicles is greater than that of non-motor vehicles, the higher the vehicle speed, the higher the danger level, and the vehicle speed at the entrance and exit is greater than that in the parking lot within the community, the importance order of the corresponding attribute values of the safety attribute is: no hazard source > near the non-motor vehicle parking lot in the community > near the motor vehicle parking lot in the community > near the entrance and exit of the community.

[0059] When formulating the importance order of the corresponding attribute values of the site type attribute in advance, it is determined according to at least one of the consideration factors of shareability and interference. In a possible implementation manner, when determining the importance order of the corresponding attribute values of the site type attribute, it is determined according to both factors of shareability and interference. Specifically, when determining the importance order of the corresponding attribute values of the site type attribute according to shareability and interference, based on the better shareability (for example, the central green space and square in the community are superior to other locations), and the smaller interference (for example, the central green space and square in the community are far from residential buildings and have less noise interference to residents' lives), the importance order of the corresponding attribute values of the site type attribute can be determined as: central green space / square in the community > sports activity site in the community > space in front of the house > other passage spaces > parking lot.

[0060] When formulating the importance order of the corresponding attribute values of the pavement status attribute in advance, it is determined according to at least one of the consideration factors of foundation and renewal cost. In a possible implementation manner, when determining the importance order of the corresponding attribute values of the pavement status attribute, it is determined according to both factors of foundation and renewal cost. Specifically, when determining the importance order of the corresponding attribute values of the pavement status attribute according to the foundation and renewal cost, based on the better foundation (for example, the foundation with both greening and hard pavement is superior to only hard pavement), and the lower renewal cost (for example, it is easier to renew only hard pavement, grassland, or wasteland), the importance order of the corresponding attribute values of the pavement status attribute can be determined as: both greening and hard pavement > only hard pavement > unmanaged wasteland > only grassland > trees, shrubs, and grass.

[0061] It is determined according to the sunlight obtained when formulating the importance order of the attribute values corresponding to the daylighting condition attributes in advance. Specifically, when determining the importance order of the attribute values corresponding to the daylighting condition attributes, the higher the score is according to the more sunlight obtained. Thus, the importance order of the attribute values corresponding to the daylighting condition attributes can be determined as: independent plot without building obstruction > located on the south side of the building with good daylighting > located on the east / west side of the building with general daylighting > located on the north side of the building with poor daylighting.

[0062] When formulating the importance order of the attribute values corresponding to the risk factors attributes in the site in advance, it is determined according to the difficulty level during the update. Specifically, when determining the importance order of the attribute values corresponding to the risk factors attributes in the site, according to the management-level problems being superior to the problems that require certain engineering measures for update (for example, monitoring problems are relatively easy to solve, while problems such as poisonous and thorny plants, uneven ground, and slopes require certain engineering measures to solve), the importance order of the attribute values corresponding to the risk factors attributes in the site can be determined as: no danger > vision blocked / no monitoring > height difference > thorny plants / poisonous plants / uneven ground.

[0063] When formulating the importance order of the attribute values corresponding to the scale attributes in advance, it is determined that the higher the scale, the higher the score.

[0064] When formulating the importance order of the attribute values corresponding to the site accessibility attributes in advance, it is determined according to the existing closed facility situation. Specifically, when determining the importance order of the attribute values corresponding to the site accessibility attributes according to the existing closed facility situation, according to the fact that completely open is superior to having a closed situation, having some fences / hedges is superior to being completely closed, and lower fences / hedges are superior to higher ones, the importance order of the attribute values corresponding to the site accessibility attributes can be determined as: completely open without fences / hedges > having fences / hedges but having an entrance / exit > having fences / hedges, the height of the entrance / exit fences / hedges is less than 0.8m > having fences / hedges, the height of the entrance / exit fences / hedges is greater than 0.8m > having fences / hedges without an entrance / exit and the height of the fences / hedges is less than 0.8m) > having fences / hedges without an entrance / exit and the height of the fences / hedges exceeds 0.8m).

[0065] When determining the importance order of the attribute values corresponding to the current facilities attributes in the area to be evaluated, it is determined according to the available facilities in the existing site. Specifically, when determining the importance order of the attribute values corresponding to the current facilities attributes in the area to be evaluated according to the available facilities in the existing site, according to the fact that having available facilities is superior to not having available facilities, the importance order of the attribute values corresponding to the current facilities attributes in the area to be evaluated can be determined as: sports activity venues > fitness facilities > entertainment facilities (such as chess tables, etc.) > no facilities.

[0066] After obtaining the importance order of the attribute values, it is used together with the attribute value score assignment rule (i.e., when scoring, the score is on a ten-point scale, with a full score of 10 points and a minimum score of 0 points) as the attribute value scoring rule. Similarly, after obtaining the importance order of the attributes, it is used together with the attribute weight assignment rule (i.e., when scoring, the scoring is carried out at a 100% scoring ratio, that is, the sum of all attribute scores is 100%) as the attribute scoring rule. Thus, the pre-established scoring rule (i.e., the assignment standard) can be obtained. It includes the attribute scoring rule (i.e., the attribute weight assignment rule) and the attribute value scoring rule (i.e., the attribute value assignment rule).

[0067] In a possible implementation manner, when using the system automatic generation method for assignment, the above assignment standard can be directly pre-stored in the system, and then the system assigns weights to each attribute in the space evaluation form and assigns values to each attribute value by calling the pre-stored assignment standard. Further, manual assignment can also be carried out by pushing the above assignment standard.

[0068] For example, referring to Table 2, it is the evaluation factor score table obtained by manually assigning values to each evaluation factor in the space evaluation form according to the assignment standard:

[0069] Table 2

[0070]

[0071]

[0072]

[0073] After obtaining the evaluation factor score table, the score results of the evaluation factors that meet the current area to be evaluated are extracted from the evaluation factor score table. Among them, when extracting the score results of the evaluation factors that meet the current area to be evaluated from the evaluation factor score table, first obtain the evaluation factors that meet the current area to be evaluated. Specifically, based on the obtained space evaluation form, conduct on-site research on the current area to be evaluated, screen out the evaluation factors that meet the current area to be evaluated from the space evaluation form, and input the screened evaluation factors that meet the current area to be evaluated into the system. Thus, the evaluation factors that meet the current area to be evaluated can be obtained, and then according to the obtained evaluation factors that meet the current area to be evaluated, the score results of the evaluation factors that meet the current area to be evaluated are extracted from the above evaluation factor score table.

[0074] It should be noted that when extracting the corresponding scoring results from the evaluation factor scoring table based on the obtained evaluation factors, it is achieved by traversing and matching the obtained evaluation factors with each evaluation factor in the evaluation factor scoring table. Specifically, when used for evaluating the current area to be evaluated, the process of obtaining the corresponding scoring result for one evaluation factor in the obtained evaluation factors is used to illustrate the process of obtaining the corresponding scoring results for each evaluation factor. That is, traverse each evaluation factor in the evaluation factor scoring table, match the traversed evaluation factor with the current evaluation factor. If the traversed evaluation factor is different from the current evaluation factor, then traverse the next evaluation factor in the evaluation factor table; when the traversed evaluation factor is the same as the current evaluation factor, extract the corresponding scoring result of the traversed evaluation factor as the scoring result of the current evaluation factor.

[0075] For example, the determined evaluation factor is the site type attribute. Traverse the attribute column in the evaluation factor scoring table to find the corresponding score for the site type attribute (i.e., 0.2 in the above table), and take the found 0.2 as the scoring result of the current site type attribute evaluation factor.

[0076] According to the process of obtaining the corresponding scoring result for one evaluation factor above, complete the process of obtaining the corresponding scoring results for each evaluation factor that meets the current area to be evaluated, thereby obtaining the scoring results of each evaluation factor that meets the current area to be evaluated.

[0077] After obtaining the scoring results of each evaluation factor for evaluating the current area to be evaluated, based on the obtained scoring results of each evaluation factor corresponding to the current area to be evaluated, obtain the scoring result of the current area to be evaluated. It should be noted here that the scoring results of the extracted evaluation factors include at least one of the attribute scoring results and the attribute value scoring results.

[0078] In a possible implementation manner, the extracted evaluation factor scoring results include both attribute scoring results and attribute value scoring results. At this time, when obtaining the scoring result of the current area to be evaluated based on the scoring results of each extracted evaluation factor (attributes and attribute values), it is achieved by calculating the sum of the products of each attribute and the corresponding attribute value scores. Specifically, when calculating the scoring result of the current area to be evaluated according to the obtained scoring results of the evaluation factor scores, it can be expressed by the formula:

[0079] Total score = Safety attribute value score * 0.2 + Site type attribute value score * 0.2 + Pavement current situation attribute value score * 0.15 + Lighting condition attribute value score * 0.1 + Risk factor score attribute value within the site * 0.05 + Scale attribute value * 0.2 + Site accessibility attribute value score * 0.05 + Current facilities attribute value score within the open space * 0.05

[0080] The total score calculated by the above formula is the score result of the currently to-be-evaluated area.

[0081] After obtaining the score result of the currently to-be-evaluated area, step S1400 is executed, and the renovation evaluation result of the currently to-be-evaluated area can be obtained according to the score result of the currently to-be-evaluated area. Specifically, when obtaining the renovation evaluation result of the currently to-be-evaluated area according to the score result of the currently to-be-evaluated area, the score result of the currently to-be-evaluated area is compared with the score threshold. When the score result is greater than the score threshold, an evaluation result that the currently to-be-evaluated area can be used for geospatial renovation is obtained; when the score result is less than the threshold, an evaluation result that the currently to-be-evaluated area cannot be used for geospatial renovation is obtained. Among them, the score threshold is determined according to the actual situation and is preferably determined to be 7.

[0082] In another embodiment of the present application, when performing a renovation evaluation on the selected to-be-evaluated area, first obtain the geospatial information of the currently to-be-evaluated area, and then extract the evaluation factors for evaluation from the geospatial information. It should be noted here that the method of obtaining the geospatial information is the same as that in the previous embodiment and will not be elaborated here.

[0083] Among them, the evaluation factors include at least one of geospatial attributes and attribute values. Specifically, referring to Table 3, the geospatial attributes include at least one of: openness, safety and accessibility, distance, area scale, slope, spatial type, adjacent adverse conditions, land use conditions, adjacent land use, lighting, and site enclosure.

[0084] For the attribute of the open situation, its attribute values may include at least one of urban public space, open community space, open paid space, and enclosed (community) space. For the attribute of safety and accessibility, its attribute values may include at least one of community roads, urban branch roads, and urban arterial roads. For the attribute of distance, its attribute values may include at least one of 300m, 500m, and 1000m. For the attribute of area scale, it can be characterized by actual numerical values. For the attribute of slope, its attribute values may include at least one of no slope, gentle slope, and steep slope (greater than 10%). For the attribute of space type, its attribute values may include at least one of urban parks, squares, and green spaces; urban sports venues, community entrance squares, community central squares or green spaces, community centralized activity spaces or small squares, front-yard spaces, pedestrian spaces, parking lots, and private gardens. For the attribute of adjacent adverse conditions, its attribute values may include at least one of none, adjacent to motor vehicle garages, adjacent to non-motor vehicle garages, adjacent to community entrances, adjacent to urban branch roads, adjacent to garbage collection points, adjacent to garbage treatment stations, adjacent to road intersections, and adjacent to arterial roads. For the attribute of land use conditions, its attribute values may include at least one of grassland, trees, shrubs and grass, hard paving, comprehensive, wasteland, and private planting. For the attribute of adjacent land use, its attribute values may include at least one of residential, office, commercial, road, and water channel. For the attribute of lighting conditions, its attribute values may include at least one of no building, south of the building, east of the building, and north of the building. For the attribute of site enclosure, its attribute values may include at least one of fully open, tall shrubs, fences, and others.

[0088]

[0089] It should be noted here that when extracting the above-mentioned evaluation factors from geospatial information, it can be directly achieved by exporting a spatial evaluation table.

[0090] That is, based on the geospatial information of the area to be evaluated determined, a spatial evaluation table (as shown in Table 4) is pre-constructed according to the determined evaluation factors. Then, when extracting the evaluation factors for evaluation from the geospatial information, the constructed spatial evaluation table can be pushed to the user. Among them, the spatial evaluation table contains attributes, attribute weights, attribute values, and the assignment of each attribute value. After obtaining the spatial evaluation table, the user can score the evaluation factors in the evaluation table according to the pre-established scoring rules to obtain the scoring result.

[0091] It should be noted that the attribute weights in the obtained space evaluation form and the corresponding assignments for each attribute value can be filled in by the user or automatically generated. Here, it should be pointed out that when filling in or automatically generating the scoring results by the user, the scoring is based on the pre-established scoring rules (i.e., the assignment criteria).

[0092] Among them, when scoring the evaluation form according to the assignment criteria, the specific assignment criteria include two types: the attribute weight assignment rule and the attribute value assignment rule. The attribute weight assignment rule includes: assigning values according to the pre-established order of attribute importance, and when assigning values, using an assignment ratio of 100%, that is, the sum of all attribute weight assignments is 100% (i.e., 1).

[0093] Here, it should be pointed out that the pre-established order of attribute importance is formulated based on at least one of the consideration factors such as the opening situation, safety, operability of renovation, and the current advantages and disadvantages of the area to be evaluated.

[0094] In a possible implementation manner, when formulating the order of attribute importance, five factors including the opening situation, safety, operability of renovation, and the current advantages and disadvantages of the area to be evaluated are considered. Specifically, when formulating the order of attribute importance, first consider the opening situation of the area to be evaluated, secondly consider the safety factor, then consider the operability of renovation factor, and finally consider the current advantages and disadvantages of the area to be evaluated. The finally obtained order of attribute importance can be determined as: opening situation > safety accessibility, distance, slope, and area scale > space type, adjacent adverse conditions, daylighting > land use conditions, site enclosure > adjacent land use.

[0095] The attribute value assignment rule includes: assigning values according to the pre-established order of attribute value importance, and when assigning values, the assignment score is on a ten-point scale, with a full score of 10 points and a minimum of 0 points. That is, the highest score for each attribute value assignment is 10 points and the lowest score is 0 points.

[0096] Among them, the pre-established order of attribute value importance is determined according to the consideration factors of its corresponding attribute. That is, the pre-established order of importance of at least one of the corresponding attribute values of the attributes such as opening situation, safety accessibility, distance, slope, and area scale, space type, adjacent adverse conditions, daylighting, land use conditions, site enclosure, and adjacent land use is formulated.

[0097] In a possible implementation manner, the pre-established order of importance of the corresponding attribute values of the attributes such as opening situation, safety accessibility, distance, slope, and area scale, open space type, adjacent adverse conditions, daylighting, land use conditions, site enclosure, and adjacent land use is formulated.

[0098] Among them, when formulating the importance order of the corresponding attribute values of the open situation attribute in advance, the open situation attribute mainly considers the accessibility and enterability of the area to be evaluated. Enterability is better than paid entry, which is better than non-invitation-only entry, which is better than the private space of the community. Therefore, the importance order of the corresponding attribute values of the open situation attribute is: urban public space > open community space > open paid space > enclosed (community) space.

[0099] When formulating the importance order of the corresponding attribute values of the safety accessibility attribute in advance, the safety accessibility is formulated according to the road grade that can reach the area to be evaluated currently. According to the wider the road or the larger the traffic flow, the faster the designed vehicle speed, and the greater the danger with the larger pedestrian flow, the importance order of the corresponding attribute values of the safety accessibility attribute can be formulated as: community road > urban branch road > urban arterial road.

[0100] When formulating the importance order of the corresponding attribute values of the distance attribute in advance, according to the walking time and endurance, the closer the distance, the better. Therefore, the importance order of the corresponding attribute values of the distance attribute is: 300m > 500m > 1000m.

[0101] When formulating the importance order of the corresponding attribute values of the area scale attribute in advance, according to the larger the scale, the more and more flexible the site types and facilities that can be accommodated, the importance order of the corresponding attribute values of the area scale attribute is formulated. Therefore, the importance order of the corresponding attribute values of the area scale attribute can be formulated as: the larger the scale, the higher the score.

[0102] When formulating the importance order of the corresponding attribute values of the slope attribute in advance, the importance order of the corresponding attribute values of the slope attribute is formulated according to the slope factor. Specifically, according to the greater the slope, the more dangerous it is, the importance order of the corresponding attribute values of the slope attribute can be formulated as: no slope > gentle slope > steep slope (greater than 10%).

[0103] When formulating the importance order of the corresponding attribute values of the space type attribute in advance, it is formulated according to the considerations of space ownership, sharing, and interference. When formulating the importance order of the corresponding attribute values of the space type attribute according to space ownership, sharing, and interference, public space is easier to utilize, share, and manage compared with other enclosed management communities. The central square and green space are easier to share and have less impact on the lives of others than the space in front of and beside houses. The amusement and leisure property sites are safer and have no interference with traffic compared with the spaces with parking and passage functions. Therefore, the importance order of the corresponding attribute values of the space type attribute can be formulated as: urban parks, squares, green spaces, urban sports venues > community central square or green space > community centralized activity space or small square > community entrance square > space in front of houses > walking space > parking lot, private garden.

[0104] When formulating the importance order of the attribute values corresponding to the adjacent adverse condition attributes, it is formulated based on considerations of adjacent facilities, bad smells, and traffic hazards. When classifying according to adjacent facilities, it can be divided into adjacent to a garbage station, adjacent to a parking lot, and adjacent to a road. According to the consideration of bad smells, when adjacent to a garbage station, the importance order of attribute values can be formulated as: smelly garbage collection point > garbage treatment station; according to the consideration of traffic hazards, when adjacent to a parking lot, the importance order of its attribute values can be formulated as: non-motor vehicle garage > community entrance / exit > motor vehicle garage; according to the consideration of traffic hazards, when adjacent to a road, the importance order of its attribute values can be formulated as: adjacent to an urban branch road > adjacent to a road intersection, adjacent to a main road.

[0105] When formulating the importance order of the attribute values corresponding to the land use condition attributes, it is formulated based on considerations of foundation and renewal costs. When formulating the importance order of the attribute values corresponding to the land use condition attributes based on considerations of foundation and renewal costs, a site with both greening and hard paving has a very good foundation and can be directly used for transformation. A site with only hard paving, grass, or wasteland is relatively easy to transform and update. A site with arbor-shrub-grass landscaping design has a higher renewal cost and greater difficulty. Private planting areas cannot be accessed and are not considered. Therefore, the importance order of the attribute values corresponding to the land use condition attributes can be formulated as: comprehensive > hard paving, grass > arbor-shrub-grass > private planting.

[0106] When formulating the importance order of the attribute values corresponding to the adjacent land use attributes, it is formulated based on considerations of safety. When formulating the importance order of the attribute values corresponding to the adjacent land use attributes based on considerations of safety, the space surrounded by residences is the preferred area with relatively high safety; commercial plazas are also frequently visited, and their design of separating people and vehicles provides greater safety assurance; there are more vehicles and less utilization in the space near office buildings; considering safety, people are not inclined to go to the areas near water systems; the areas on both sides of the road are the most dangerous areas. Therefore, the importance order of the attribute values corresponding to the adjacent land use attributes can be formulated as: residence > commerce > water, office > road.

[0107] When formulating the importance order of the attribute values corresponding to the lighting attributes, it is formulated based on the sunlight obtained. The more sunlight obtained, the higher the score. Therefore, the importance order of the attribute values corresponding to the lighting attributes can be formulated as: no building > south of the building > east / west of the building > north of the building.

[0108] When formulating the attribute values corresponding to the site enclosure attribute, it is formulated based on the enclosure situation of the site. That is, completely open is better than having an enclosure situation, and plant enclosure is better than artificial fence enclosure. Therefore, the importance order of the attribute values corresponding to the site enclosure attribute can be formulated as: completely open > having hedges > having fences.

[0109] Based on the above-obtained order of attribute importance and order of attribute value importance, a complete assignment standard is obtained. That is, the attribute weight assignment rule and the attribute value assignment rule. Thus, the pre-specified scoring rule (i.e., the assignment standard) can be obtained.

[0110] Then, score each evaluation factor in the obtained space evaluation form according to the pre-developed scoring rule to obtain an evaluation factor score table (i.e., Table 4).

[0111] In a possible implementation manner, when scoring the obtained space evaluation form according to the pre-developed scoring rule in the way of system automatic generation, the above scoring rule can be pre-stored in the system first, and then the pre-stored scoring rule is called to assign values to each attribute weight and each attribute value in the space evaluation form. Further, manual assignment can also be performed by pushing the scoring rule.

[0112] For example, referring to Table 4, it is an evaluation factor score table obtained by manually assigning values to each evaluation factor in the space evaluation form according to the scoring rule:

[0113] Table 4

[0114]

[0115]

[0116]

[0117]

[0118] After obtaining the evaluation factor score table, extract the scoring results of the evaluation factors that meet the current area to be evaluated from the evaluation factor score table. Among them, when extracting the scoring results of the evaluation factors that meet the current area to be evaluated from the evaluation factor score table, first obtain the evaluation factors that meet the current area to be evaluated. That is, based on the obtained space evaluation form, conduct on-site research to screen out the evaluation factors that meet the current area to be evaluated and input them into the system. Thus, the evaluation factors that meet the current area to be evaluated can be obtained. Then, based on the obtained evaluation factors that meet the current area to be evaluated, extract the scoring results of each obtained evaluation factor from the evaluation factor score table.

[0119] It should be noted that when extracting the scoring results of the evaluation factors that meet the current area to be evaluated from the evaluation factor score table, it is achieved by traversing and matching the obtained evaluation factors with the evaluation factors in the evaluation factor score table. And the specific process of its traversing and matching is the same as that in the previous embodiment, and will not be elaborated here too much.

[0120] Thus, the scoring results of the evaluation factors that meet the current area to be evaluated can be obtained. Then, based on the scoring results of each extracted evaluation factor, the scoring result of the current area to be evaluated is calculated. That is, in a possible implementation manner, the scoring results of the extracted evaluation factors include two types: attribute scoring results and attribute value scoring results. When calculating the scoring result of the current area to be evaluated according to the corresponding scoring results of each extracted evaluation factor, it can be expressed by the formula:

[0121] Total score = Openness attribute value * 0.2 + Safety and accessibility attribute value * 0.15 + Distance attribute value * 0.15 + Area scale attribute value * 0.15 + Slope attribute value * 0.15 + Space type attribute value * 0.05 + Adjacent adverse condition attribute value * 0.05 + Land use condition attribute value * 0.02 + Adjacent land use attribute value * 0.01 + Lighting attribute value * 0.05 + Site enclosure attribute value * 0.02

[0122] According to the above calculation formula, the scoring result of the current area to be evaluated can be obtained. Then, based on the scoring result of the current area to be evaluated, the renovation evaluation result of the current area to be evaluated can be obtained. That is, the calculated scoring result is compared with a pre-determined scoring threshold. When the scoring result is greater than the scoring threshold, it is obtained that the current area to be evaluated can be used for the evaluation result of geospatial renovation; when the scoring result is less than the scoring threshold, it is obtained that the current area to be evaluated cannot be used for the evaluation result of geospatial renovation. Among them, the scoring threshold is determined according to the actual situation, and is preferably determined to be 7.

[0123] Thus, the present application provides a geospatial renovation evaluation method, including: obtaining the geospatial information of the current area to be evaluated; extracting the evaluation factors for evaluation from the geospatial information; scoring the evaluation factors according to a pre-formulated scoring rule to obtain a scoring result; and obtaining the renovation evaluation result of the geospatial based on the scoring result. The above method scores each evaluation factor of the geospatial through a pre-formulated scoring rule to finally obtain a quantified scoring result, and evaluates the current geospatial renovation potential based on the quantified evaluation result. Its quantified evaluation method realizes automatic evaluation and no longer completely relies on manual evaluation, thereby improving the efficiency of geospatial renovation evaluation.
