Geographic information systems (GIS, geographic Information Systems) technology is a geospatial-based system that provides a variety of spatial and dynamic geographic information for geographic research and geographic decision services. With the continuous development of geographic information systems, more and more geographic information is contained in a geographic space, and users need to inquire about target geographic information as soon as possible, wherein the target geographic information comprises coordinate information and attribute information of things distributed in an earth indication space, the attribute information is used for representing what is specifically on the earth, and the coordinate information is used for representing the exact position where the things occur.
In the prior art, when a user queries target geographic information in a geographic information system, specific coordinate information and specific attribute information of the target geographic information need to be input or selected for query.
However, when the user queries information with some identical attributes, the search response time of the prior art is long, and the search efficiency is low.
In view of this, embodiments of the present application provide a geospatial data processing method, apparatus, computer device, and storage medium, which can improve the efficiency of searching for target geographic information by a user.

As shown in fig. 1, the implementation environment may include a terminal 101 and a server 102, wherein the terminal 101 communicates with the server 102 through a network. The terminal 101 inputs the target keyword to the server 102 through the network, and the server 102 outputs the target coordinate information and the target attribute information to feed back to the terminal 101 by executing the geospatial data processing method provided in the embodiment of the present application. The terminal 101 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices, and the server 102 may be implemented by a stand-alone server or a server cluster formed by a plurality of servers.
Referring to fig. 2, a flowchart of a geospatial data processing method according to an embodiment of the present application is shown, where the geospatial data processing method may be applied to the server 102 in the implementation environment described above. As shown in fig. 2, the geospatial data processing method may include the steps of:
step 201, the server queries a geographic space database based on target keywords input by a user, and determines at least one target geographic space corresponding relation through query.
The geographic space database comprises a plurality of geographic space corresponding relations, each geographic space corresponding relation comprises an index, coordinate information and attribute information, the index comprises keywords in the coordinate information and the attribute information, and the keywords included in the index of the target geographic space corresponding relation are matched with the target keywords.
In the embodiment of the present application, the attribute information may be a construction plan of a certain town or a certain town in a certain year, such as "xian city xishan Xin district" or "xian city xishan Xin district recent construction plan (2008-2010)".
The coordinate information may be the exact location in the area of a town or year construction plan, where the area is to be construed broadly and may refer to the earth's surface or a predetermined portion of the earth's surface. For example, when the region is defined as Shaanxi province, the coordinate information may be the exact position in Shaanxi province of a certain town or a certain year of construction plan, that is, the longitude and latitude information of a specific position. When the attribute information is "xian city xiyan new area" or "xian city xiyan new area recent construction plan (2008-2010)", the coordinate information is vector data of specific positions of xian city xiyan new area and xian city xiyan new area recent construction plan (2008-2010) in shanxi province, and the vector data can be stored in a kml format, an excel format and the like.
The index includes keywords in the attribute information, and can be obtained by word segmentation, for example, when the attribute information is "new western salty region recent construction plan (2008-2010)" in western city, the index can be set to "new western salty region", "construction", "plan", "2008", "2010" … … in western city ".
In summary, one geospatial correspondence in the embodiments of the present application may be:
index: "western Anshi city", "Western salty New district", "construction", "planning", "2008", "2010" … …;
attribute information: 'New West salty New district recent construction plan in Siam City (2008-2010)'
Coordinate information: vector data of a specific location in the Shaanxi province of recent construction planning (2008-2010) in the new West salty region of the West An city.
Another geospatial correspondence in this application may be:
index: "Simian City", "New West salty region";
attribute information: "New West salty district in Siam City";
coordinate information: vector data of specific positions in Shaanxi province in the West salty New region of West An city.
The server establishes a geographic space corresponding relation comprising an index, attribute information and coordinate information, and after a user inputs a target keyword, the target geographic space corresponding relation is determined by matching the index with the attribute information and the coordinate information. For example, when the target keyword is "new western salty region", a target geospatial correspondence relationship corresponding to attribute information including "new western salty region of western city recent construction plan (2008-2010)" and "new western salty region of western city" may be obtained.
In an alternative embodiment of the application, the terminal queries the geospatial database based on keywords filled in by the user; and/or querying a geospatial database based on the user selected keywords.
For example, the user can input the keywords to be queried into the front-end page of the geospatial database in the terminal to query, or query the keywords displayed by the front-end page of the geospatial database.
In another optional embodiment of the present application, the terminal may further query the geospatial database based on the coordinate information input by the user, and determine at least one target geospatial correspondence by querying, where the target geospatial correspondence matches the coordinate information. For example, a user may input longitude and latitude vector data of a new western-style salty region in western-style city and a specific position of a recent construction plan (2008-2010) in western-style salty region in shanxi province in an input box, and the user may also select a grid pattern in an area displayed on a front end page of a geospatial database to input longitude and latitude vector data corresponding to the grid pattern, and the user may obtain a geospatial correspondence based on the coordinate information by inputting the coordinate information.
In the embodiment of the application, a user can match a target geographic space corresponding relation in a geographic space data database through input or selected keywords, and can also match the target geographic space corresponding relation in the geographic space data database through input or selected coordinate information.
Step 202, the server determines target geographic information from coordinate information and attribute information included in at least one target geographic space corresponding relation.
In the embodiment of the present application, each keyword may correspond to a plurality of target geospatial correspondence relationships, for example, when a user inputs "new western salty region", the target geospatial correspondence relationships that may be obtained may include:
(1) Index: "Simian City", "New West salty region", "Da Wang Zhen", "plan", "2012";
attribute information: "West salty New district of Siam City was planned by Wang Zhen, programming time 2012";
the coordinate information is vector coordinate data corresponding to the attribute information in the geographic space database.
(2) Index: "Simian City", "West salty New district", "West New City Feng", "south tablet district", "planning", "2011";
attribute information: "the control detailed planning of the southern area of Fengxi New City in the West An City, programming time 2011";
the coordinate information is vector coordinate data corresponding to the attribute information in the geographic space database.
(3) Index: "Simian City", "West salty New district", "West New City Feng", "south tablet district", "plan", "2015";
attribute information: "control detailed planning of southern area of Fengxi New City in West An City, programming time 2015";
the coordinate information is vector coordinate data corresponding to the attribute information in the geographic space database.
(4) Index: "Simian City", "West salty New district", "West New City Feng", "North tablet district", "planning", "2011";
attribute information: "the control detailed planning of the north part of the New City of Feng xi Xincheng in the West An city, the programming time 2011";

In the embodiment of the application, the target geographic information is further determined according to the coordinate information and the attribute information included in the at least one target geographic space corresponding relation, and the target geographic information includes the target coordinate information and the target attribute information.
In an alternative embodiment of the present application, the number of target geospatial correspondences obtained by narrowing the keywords may be further input and selected, for example, on the basis of inputting "xishanxinjun" the keyword "xishicheng" is selected, then (2) (3) (4) of the target geospatial correspondences may be obtained, and the target geospatial correspondences (1) are excluded, and further (2) and (3) of the target geospatial correspondences may be obtained by selecting the keyword "southern region", and the target geospatial correspondences (4) are excluded. When a user needs to compare the planning of the southwest section of the west salty new district of the west safe city in different years, at least two target geospatial corresponding relations, namely the target geospatial corresponding relations (2) and (3), can be obtained by inputting or selecting keywords of the west salty new district, the Feng west new district, the southwest section of the west salty new district of the west safe city, the planning time 2015 years, the planning time of the southwest section of the west salty new district of the west safe city, the planning time 2011 year, and the input attribute information of the required completion of the inquiry can be compared, the embodiment of the application can lock the data in the geospatial database below the indexes of the west salty new district, the Feng west new district, the southwest section of the west salty new district, compared with the prior art, the embodiment of the application needs to search in the whole geospatial database for two times, and the search time of the southwest section of the west salty new district in the whole geospatial database is reduced, and the search time of the southwest section of the southwest district in the whole is required.
Step 203, the server outputs target coordinate information and target attribute information corresponding to the target geographic information.

Step 302, the server performs word segmentation on the attribute information, and a plurality of words obtained after word segmentation are established as indexes.
In the embodiment of the application, the server performs word segmentation on the obtained attribute information, for example, when the attribute information is "western-style new city is in western-style new city, and the control of the southern region of the western-style new city is planned in detail, after word segmentation is performed in the programming time 2011," western-style new region, "" the western-style new city, "" the southern region, "" … …, "and the like, because the" programming time, "" the detailed, "and the like belong to words commonly used in each attribute information, the words can be shielded through setting. The obtained "xixian new region", "keshi new city", "south region" … … and the like are used as indexes of the attribute information.
