Technical Field

[0001] The present invention belongs to the technical field of spatial data processing, and in particular relates to a spatial data processing method and system based on GIS. Background Art

[0002] GIS (Geographic Information System) is a computer system used to capture, store, analyze and manage geospatial data. It can process geospatial data, which is related to locations on the earth, including various attributes and statistical information of geographical features. GIS technology is widely used in many fields such as urban planning, environmental management, transportation and logistics, disaster prevention, etc. Through maps and spatial analysis tools, it helps users understand, query and visualize spatial data, so as to make more informed decisions.

[0003] However, there are still some shortcomings in the existing GIS-based spatial data processing research. First, traditional GIS methods are not good at integrating multi-source heterogeneous data, which limits their efficiency and accuracy in processing large-scale and diverse data sets. Secondly, these methods are mainly oriented towards static spatial data processing, and lack support for the analysis of spatiotemporal dynamic changes, making it difficult to meet the needs of dynamic phenomenon analysis. In addition, traditional GIS lacks dynamic response capabilities, resulting in the inability to update dynamic data to the GIS system in real time, causing decision-making delays. Finally, the existing dynamic data processing process relies too much on manual operations and is inefficient, which may cause information to become outdated in a rapidly changing environment, affecting the timeliness and accuracy of decision-making.

[0050] Figure 2 It is a schematic diagram of system module connection of the present invention. DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0052] Example 1: Figure 1 As shown, the GIS-based spatial data processing method includes: based on GIS, obtaining target spatial data, and the target spatial data specifically includes target spatial dynamic environment data, target spatial natural geographical data, and target spatial infrastructure data.

[0053] The target space dynamic environment data include the space environment PM2.5 concentration, space environment temperature deviation rate, space environment wind speed, and space environment precipitation intensity; the target space natural geographical data include the space environment terrain slope, the proportion of space environment vegetation coverage area, and the average turbidity of natural water bodies in the space environment; the target space infrastructure data include the space environment satellite communication coverage ratio and the space environment transmission line normal operation ratio.

[0054] PM2.5 is an important indicator for measuring air quality. A high concentration indicates that there are more fine particles in the air and the environmental quality is poor. The temperature deviation rate refers to the degree of deviation of the ambient temperature in a space from a reference temperature (such as the multi-year average temperature or standard temperature), usually expressed as a percentage. The deviation rate is the ratio of the absolute value of the difference between the actual value and the reference value to the reference value. The average turbidity of a natural water body refers to the average concentration of suspended particulate matter in the water body, usually expressed in turbidity units (NTU). It indicates the cleanliness of the water body. Higher turbidity is usually related to poor water quality, sediment disturbance or pollution. The satellite communication coverage ratio refers to the proportion of the area covered by satellite communication signals within a certain space range to the total area, usually expressed as a percentage. The normal operation ratio of transmission lines refers to the proportion of the length of transmission lines in normal operation within the target space range to the total length of transmission lines, usually expressed as a percentage.

[0055] The dynamic environmental data of the target space are analyzed to obtain the dynamic environmental status index of the target space, and the natural geographical influencing factors and infrastructure influencing factors of the target space are determined.

[0056] The specific analysis process is as follows: Based on the dynamic environmental data of the target space, a comprehensive analysis is performed to obtain the dynamic environmental status index of the target space. The dynamic environmental status index of the target space is used as the analysis basis for determining the natural geographical influencing factors of the target space and the influencing factors of the infrastructure of the target space.

[0057] The analysis of the dynamic environmental status index of the target space improves the calculation accuracy of the natural geographical influencing factors and infrastructure influencing factors. The dynamic environmental status index can directly affect the natural geographical conditions and help accurately identify the main driving factors of the dynamic environment on the natural geographical elements (such as terrain stability and land utilization rate). Dynamic environmental conditions will directly or indirectly affect the infrastructure and may accelerate the aging of infrastructure. It is necessary to clarify the potential threats of the dynamic environment to the infrastructure status, help identify weak links in advance, and reduce risks. The dynamic environmental status index can reflect the real-time changes of the target space environment, update the natural geographical and infrastructure influencing factors in real time, and ensure the timeliness of the analysis results.

[0058] Furthermore, the formula for obtaining the target space dynamic environment state index is:

[0059] ;

[0060] In the formula, α is the dynamic environment state index of the target space, PM is the PM2.5 concentration of the space environment, wdp is the temperature deviation rate of the space environment, fs is the wind speed of the space environment, jsq is the precipitation intensity of the space environment, , , , They are the compensation factors of PM, wdp, fs and jsq respectively.

[0061] When calculating each formula, normalization processing is performed as needed. Each compensation factor is obtained from a database by establishing a mapping set based on historical data. Other known methods can also be used to set the compensation factor.

[0062] The PM2.5 concentration, temperature deviation rate, wind speed and precipitation intensity of the space environment are the core elements of the dynamic environment, which describe the environmental status from four dimensions: air quality, temperature anomaly, atmospheric dynamics and precipitation conditions. The status index is dynamically updated by real-time monitoring of changes in PM2.5 concentration, temperature deviation rate, wind speed and precipitation intensity. Dynamic monitoring of the target space environment status is achieved, environmental anomalies are quickly identified, the linkage effect of environmental variables is more accurately reflected, and the environmental risk early warning capability is improved.

[0063] The dynamic environmental status index of the target space is stored as a designated label, and the designated label is compared with each set label stored in the database to obtain the set label corresponding to the designated label, and the natural geographical impact factor of the target space and the infrastructure impact factor of the target space corresponding to the set label are obtained.

[0064] The dynamic environmental status index is stored in the form of specified tags. The structured management method of tags can be quickly classified, retrieved and associated. By setting tags, the relationship between the dynamic environmental status index and natural geography and infrastructure is clarified. After the dynamic environmental status index is stored in a tagged form, it can be compared with real-time updated data to quickly obtain the influencing factors in the current state, reduce manual operation errors, and ensure the accuracy of the comparison results. Support data automation processing to improve the accuracy of analysis and decision-making.

[0065] The physical geographic data of the target space are analyzed and combined with the physical geographic influencing factors of the target space to obtain the physical geographic status index of the target space.

[0066] The specific analysis process is as follows: based on the natural geographic data of the target space and combined with the natural geographic influencing factors of the target space, a comprehensive analysis is performed to obtain the natural geographic status signal of the target space, and the natural geographic status signal of the target space is used as the analysis basis for obtaining the natural geographic status index of the target space; the natural geographic status signal of the target space is stored as a specified label, and the specified label is compared with each set label stored in the database to obtain the set label corresponding to the specified label, and the natural geographic status index of the target space corresponding to the set label is obtained.

[0067] The physical geographic state signal is stored in a tagged manner to form a unified data management framework. Through tag comparison, the state signal and state index are quickly associated. Through automation, batch analysis of large-scale data is achieved, supporting the rapid processing of complex physical geographic data sets. The physical geographic state signal integrates a variety of influencing factors (such as terrain, soil, vegetation, water system, etc.), reflects the overall state of physical geography, and can accurately capture the complexity of physical geographic changes in the target space. Provide a basis for ecological protection, resource planning and risk management.

[0068] Furthermore, the formula for obtaining the natural geographic status signal of the target space is:

[0069] ;

[0070] Where β is the natural geographic state signal of the target space, is the natural geographical influencing factor of the target space, pd is the terrain slope of the spatial environment, fg is the proportion of vegetation coverage area in the spatial environment, zd is the average turbidity of natural water bodies in the spatial environment, , , are the compensation factors of the set pd, fg, and zd respectively.

[0071] The target space natural geographic state signal can reveal the characteristics of terrain undulation, affect soil erosion and precipitation runoff, reflect the health of the ecosystem and the carbon sequestration capacity of the region, and measure the water quality and ecological environment. A single state signal is generated by comprehensive calculation of multiple natural geographic indicators to support the refined management of natural resources. The natural geographic state signal can quantify the terrain suitability, ecological carrying capacity and water resource conditions of the region, locate vulnerable areas, and optimize resource input.

[0072] The target space infrastructure data is analyzed and combined with the target space infrastructure influencing factors to obtain the target space infrastructure status index.

[0073] The specific analysis process is as follows: based on the target space infrastructure data and combined with the target space infrastructure influencing factors, a comprehensive analysis is performed to obtain the target space infrastructure status signal, and the target space infrastructure status signal is used as the analysis basis for obtaining the target space infrastructure status index; the target space infrastructure status signal is stored as a specified tag, and the specified tag is compared with each set tag stored in the database to obtain the set tag corresponding to the specified tag, and the target space infrastructure status index corresponding to the set tag is obtained.

[0074] By storing infrastructure status signals with specified tags, complex data can be structured and managed, simplifying the data retrieval process and facilitating the rapid call of relevant status signals. Efficient conversion of data to status index can be achieved through automation of labeling and comparison process. Rapid association of infrastructure status signals and status index can be achieved by comparing set tags with specified tags. Reduce the need for manual intervention and improve the automation level of status index calculation. Status signals comprehensively consider multiple influencing factors and fully reflect the status of infrastructure. Stored tags and corresponding status indexes can be used to analyze the changing trend of facility status. Support intelligent prediction and trend analysis to promote the intelligent upgrade of facility management.

[0075] The formula for obtaining the target space infrastructure status signal is:

[0076] ;

[0077] In the formula, It is the target space infrastructure status signal. is the impact factor of the target space infrastructure, wxt is the satellite communication coverage ratio of the space environment, zcy is the normal operation ratio of the space environment power transmission line, is the compensation factor of the set wxt, is the compensation factor of the set zcy, and e is a natural constant.

[0078] The target space infrastructure status signal provides a comprehensive assessment of the infrastructure status, reflects the health status of the infrastructure in multiple dimensions, and combines the dynamic data of satellite communications and transmission lines to generate signals reflecting the current infrastructure operation status, quickly identify facility anomalies or failures, and support emergency response. The status signal combined with infrastructure influencing factors (such as environmental conditions and facility aging) can assess potential risks. The infrastructure status signal can quantify the facility demand and operating status of each region, prioritize the allocation of resources to areas with abnormal operation or insufficient coverage, reduce resource waste, and improve maintenance efficiency.

[0079] The target space dynamic environment status index, target space natural geographical status index, and target space infrastructure status index are uploaded to the online GIS platform, and the data upload process is analyzed to determine whether the data upload process is successful: if the data upload process is unsuccessful, the target space dynamic environment status index, target space natural geographical status index, and target space infrastructure status index are retransmitted; if the data upload process is successful, based on the online GIS platform, the target space dynamic environment status index, target space natural geographical status index, and target space infrastructure status index are displayed online using WebGIS technology.

[0080] The specific analysis process is: obtaining the target space dynamic environment status index, the target space natural geographic status index, and the target space infrastructure status index upload process data, including data upload delay, data upload network bandwidth, and data upload transmission rate;

[0081] Based on the acquired target space dynamic environment status index, target space natural geographic status index, and target space infrastructure status index upload process data, a comprehensive analysis is performed to obtain a data upload process analysis factor, which is used as an analysis basis for judging whether the data upload process is successful; the data upload process analysis factor is compared with the data upload process analysis threshold stored in the database;

[0082] If the data upload process analysis factor is not lower than the data upload process analysis threshold, the data upload process corresponding to the data upload process analysis factor is successful. Based on the online GIS platform, the WebGIS technology is used to realize the online display of the target space dynamic environment status index, the target space natural geographical status index, and the target space infrastructure status index.

[0083] If the data upload process analysis factor is lower than the data upload process analysis threshold, the data upload process corresponding to the data upload process analysis factor is unsuccessful, and the target space dynamic environment status index, target space natural geographical status index, and target space infrastructure status index are retransmitted.

[0084] Based on the online GIS platform, using WebGIS technology, the three indexes are displayed on the target spatial area map. In the center of the target area, a radar chart of the three indexes is drawn to display the dynamic environment, natural geography and infrastructure status. The values ​​of the three status indexes in each area are updated in real time and dynamically reflected on the map. A time slider function is provided to allow users to trace the past trend of changes in the status index. Clicking or touching the area with the mouse will pop up a window to display the three status index values ​​and detailed information of the area. Map display is achieved based on ArcGISOnline, Mapbox, Leaflet.js, etc., and the status index data is stored through PostGIS or MongoDB to support fast query. JavaScript frameworks (such as React.js, Vue.js) are used in combination with GISAPI to develop dynamic interactive interfaces. The chart expression of the status index is enhanced based on data visualization tools (such as D3.js, ECharts).

[0085] By collecting indicators such as data upload delay, network bandwidth and transmission rate, an upload process analysis factor is formed to dynamically monitor the upload status. Accurately identify problems that may occur during the upload process and improve the success rate of upload. By comparing the upload process analysis factor recorded in the database with the analysis threshold, the abnormal status of the upload process can be tracked. When the upload process analysis factor is lower than the set threshold, data retransmission is automatically triggered. Avoid data loss or incompleteness due to unknown reasons. Only when the upload process is successful, the target spatial status index is uploaded to the online GIS platform to ensure that the data displayed on the WebGIS platform is accurate and avoid displaying erroneous or incomplete data due to upload failure. Reduce repeated calculations and data repairs caused by upload failures.

[0086] The formula for obtaining the analysis factor during data upload is:

[0087] ;

[0088] In the formula, is the data upload process analysis factor, sy is the data upload delay, dk is the data upload network bandwidth, sl is the data upload transmission rate, , , are the compensation factors of the set sy, dk, and sl respectively.

[0089] Data upload latency reflects response speed, network bandwidth determines theoretical transmission capacity, and transmission rate reflects actual upload efficiency. A single indicator can directly reflect the quality of the upload process and support rapid analysis and evaluation of the upload process. The analysis factor can reflect changes in upload latency, bandwidth, and transmission rate in real time through dynamic calculation. This reduces manual intervention and improves the automation and intelligence level of upload tasks.

The dynamic environmental state index of the target space is calculated to be 102.23, and the natural geographical impact factor of the target space is determined to be 1.5, and the infrastructure impact factor of the target space is 2.0.

The target space natural geographical state signal is calculated to be 2.49, and the target space natural geographical state index is determined to be 59.8.

The target space infrastructure status signal is calculated to be -2.62, and the target space infrastructure status index is determined to be 4.76.

[0093] The data upload delay is 0.1s, the data upload network bandwidth is 10Mbps, the data upload transmission rate is 8Mbps, the compensation factor of the data upload delay is 0.5, the compensation factor of the data upload network bandwidth is 0.4, and the compensation factor of the data upload transmission rate is 0.3. The data upload process analysis factor is calculated to be 63.17, which is not less than the data upload process analysis threshold of 60. The data upload process corresponding to the data upload process analysis factor is successful. Based on the online GIS platform and using WebGIS technology, the online display of the target space dynamic environment status index, target space natural geographical status index, and target space infrastructure status index is realized.
