The method has the advantages of high geographic information data collection efficiency, flexible collection methods and accurate and reliable data collection.

[0043] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0044] In one embodiment of the present invention, Figure 2 As shown, a method for multiple people to collaboratively collect thematic geographic information data includes:

[0045] Step S201, determining the data standard of the thematic geographic information to be collected, and establishing the layers of the geographic information database according to the data standard, wherein the data standard includes: layer classification standard, vector graphics standard and attribute information standard;

[0046] In this embodiment, the layer classification standard refers to the number and name of the layers of thematic geographic information that need to be collected. For example, the collection of thematic data of educational facility space business can be divided into five layers: higher education, high school, junior high school, elementary school and kindergarten;

[0047] The vector graphics standard includes a coordinate system, an elevation system, and a geometric feature definition. For example, the coordinate system may be the 2000 National Geodetic Coordinate System or the 2000 Tianjin City Coordinate System. The geometric feature definition includes spatial points, lines, and surfaces. In this embodiment, the geometric feature definition is a point position.

[0048] Attribute information standards include field name, field type, field length, and constraints.

[0049] Exemplarily, in this embodiment, the attribute information standard includes:

[0050]

[0051]

[0052] In this embodiment, data standards are the basis for collecting business-specific data. Determination of data standards can ensure the quality of data and provide a high-quality foundation for subsequent data collection.

[0053] In this embodiment, the attribute information of the collected data corresponds to each set layer.

[0054] Step S202, performing data verification on the geographic information collected by several data collectors according to the data standard according to the set verification standard;

[0055] Data collectors include indoor data collectors and outdoor data collectors, such as Figure 4 As shown, indoor data collectors collect geographic information based on existing basic data, and outdoor data collectors collect geographic information on-site.

[0056] In this embodiment, the existing basic data includes, for example, electronic maps, remote sensing images and other existing basic data.

[0057] Obtaining geographic information collected by data collectors according to data standards, and performing data verification on the geographic information according to set verification standards;

[0058] Verification criteria include: whether the collected geographic information is repeated and whether it complies with data standards.

[0059] In this embodiment, whether the collected geographic information is repeated and whether it meets the data standard specifically includes the following:

[0060] Whether the geographic information is repeated, including:

[0061] Are there any duplicate addresses or close locations?

[0062] Are there any duplicate names? For example, duplicate school names.

[0063] Whether the geographic information complies with data standards, including:

[0064] Check whether the required items of each layer's attribute information have been filled in; for example, the school name is a required item;

[0065] The consistency of the field value type with the standard of the field;

[0066] The rationality of the field value; for example, the value of the number of students in school is significantly higher than the per capita building area;

[0067] The setting of verification standards can effectively ensure the accuracy of the collected geographic information.

[0068] Step S203, combining and generating a first geographic information database based on the geographic information that has passed the data verification and the layers of the geographic information database;

[0069] Step S204: Perform a quality check on the first geographic information database according to the verification standard, and correct the data in the first geographic information database that does not meet the verification standard to generate a second geographic information database for representing thematic geographic information.

[0070] In this embodiment, the quality inspection method may also include:

[0071] Use spatial topology checking technology to check spatial graphic overlap;

[0072] Use word segmentation technology to perform fuzzy duplication check on attribute information;

[0073] Compare the consistency between the district and county where the spatial location is located and the district and county to which the attribute information belongs.

[0074] Correcting the data in the first geographic information database that does not meet the verification standards includes: feeding back the data that does not meet the verification standards to the corresponding data collector for correction, and then performing a quality check on the first geographic information database again.

[0075] In another embodiment of the present invention, Figure 3 As shown, based on the geographic information that has passed the data verification and the layers of the geographic information database, a first geographic information database is generated by combining, including:

[0076] Establishing Excel table data composed of geographic information collected by indoor data collectors and verified by data, wherein the attribute information of each piece of geographic information includes place name and address information;

[0077] Perform word segmentation on the place name and address information, calculate the similarity between the words after word segmentation and the addresses in the pre-stored place name and address database with the place name and address coordinates, and determine the coordinates of the address with the highest similarity as the coordinates of the place name and address information;

[0078] According to the coordinates of the place name and address information, the points of the corresponding layer of the corresponding geographic information in the first geographic information database are drawn, and the corresponding attribute information is added to the points.

[0079] For example, taking the collection of school-related data as an example, firstly, the school name, address, school type, floor area, number of students and other information are collected and integrated to form Excel table data. Then, the batch space is located, specifically, the school place name and address information is segmented, the words after segmentation are searched and matched with the addresses in the place name and address database with place name and address coordinates, the similarity with the addresses in the address database is calculated, and the coordinate information of the address with the highest similarity is used as the coordinate information of the school place name and address information. Furthermore, the geographic information technology is used to draw the point position of the school in the corresponding layer, and further, the other attribute information of the school is analyzed, and the graphic attribute information is associated with the unified identification code, and the corresponding attribute information is added to the point position to generate a geographic information database layer with integrated graphic attributes.

[0080] In this embodiment, batch data collection and automatic coordinate placement based on Excel tables can greatly improve the efficiency of data collection and the efficiency of generating geographic information database layers with integrated graphic attributes.

[0081] In another embodiment of the present invention, Figure 3 As shown, based on the geographic information that has passed the data verification and the layers of the geographic information database, a first geographic information database is generated by combination, including: the indoor data collector collects geographic information by a single entry method, wherein the attribute information of each piece of geographic information includes place name and address information;

[0082] Search for place name and address information in a pre-stored place name and address database with place name and address coordinates, obtain the coordinates of the same address as the coordinates of the place name and address information, draw the points of the corresponding geographic information in the corresponding layer of the first geographic information database according to the coordinates of the place name and address information, and add the corresponding attribute information to the points.

[0083] For example, the data collector enters a single piece of attribute information such as the school name, address, school type, floor area, number of students, etc., searches for the school's address in an address database with coordinate information, obtains the coordinates of the same address as the school's coordinates, and draws the school's point in the corresponding layer based on the coordinates to obtain a geographic information database layer with integrated graphic attributes.

[0084] In this embodiment, a single entry method is used to supplement the batch data collection method based on Excel tables in the previous embodiment, enrich the data collection method, and improve the applicability of data collection.

[0085] In another embodiment of the present invention, Figure 3As shown, the outdoor data collector collects geographic information on-site, including: the outdoor data collector arrives at the on-site collection location of the geographic information, enters the geographic information including the place name and address information through the mini program tool, and obtains the coordinates of the place name and address information through GPS positioning;

[0086] In this embodiment, illustratively, the geographic information entered through the mini-program tool includes: school name, address, school type, floor area, number of students, and other attribute information.

[0087] In this embodiment, if Figure 3 As shown, any of the three methods, Excel spreadsheet batch collection, single entry collection and field collection, can be collected simultaneously by multiple people. The combination of Excel spreadsheet batch collection, single entry collection and field collection according to actual needs can effectively improve the applicability of this method.

[0090] The data verification module 402 verifies the geographic information collected by several data collectors according to the data standard according to the set verification standard;

[0091] A first generating module 403 is used to generate a first geographic information database based on the geographic information that has passed the data verification and the layers of the geographic information database;

[0092] The second generating module 404 is used to perform a quality check on the first geographic information database according to the verification standard, and to correct the data in the first geographic information database that does not meet the verification standard, so as to generate a second geographic information database for representing the thematic geographic information.
