Wherein, the specific geographic entity can be any one or more of a fault, a borehole and a roadway.
A coal mine data storage method provided in an embodiment of the present invention will be described in detail below, and as shown in fig. 2, the method may include the following steps:
step 201: and receiving an externally input coal mine data file.
Step 202: reading the suffix of the coal mine data file.

Step 205: and analyzing the coal mine data file by using the determined analysis model to obtain spatial data and attribute data.
Step 206: and creating a geometric information space table and a space attribute information table according to a preset unified storage rule.
In the embodiment of the present invention, the geometric information space table and the spatial attribute information table may be created by using an SQL statement, and specifically, both the geometric information space table and the spatial attribute information table may be created according to a preset unified storage rule (for example, the geometric information space table includes storage rules such as those several spatial fields). The AddGeometryColumn function may be used to create the space field, the key code is as follows: the ELECT AddGeometryColumn ('rows', 'get', 423, 'LINESTRING',2), where the parameters represent data indication, spatial field name, coordinate system, spatial type, dimension, respectively.
Step 207: and storing the spatial data obtained by analysis into a geometric information spatial table, and storing the attribute data obtained by analysis into a spatial attribute information table.
In the embodiment of the present invention, the key codes when the spatial data and the attribute data obtained by the analysis are inserted into the corresponding table may be as follows:
INSERT INTO ROADS(id,road_name,geom)
VALUES(1,'Jeff Rd',ST_GeomFromText('LINESTRING(191232243118,191108 243242)',4326))；
after the data is inserted into the corresponding table, a corresponding spatial index can be created, specifically, the layer is an index of the entity data, the layer set is an index of the layer, the map is an index of the layer set, the map set is an index of the map, and the like.
It is worth noting that embodiments of the present invention can provide range, distance, and SQL based queries. Wherein, the key codes involved in the range-based query can be as follows:
select*from${tableName}where
ST_DWithin("${geomColumn}",ST_GeomFromText('POINT(${longitude}${latitude})',${srid}),${distance})
when the query is based on the range, the Bounds of the corresponding geometric object can be calculated according to the received query condition, and the object which meets a certain spatial relationship and query condition with the specified geometric object is queried by comparing the spatial position relationship between the Bounds and the geometric object.
The key codes involved in the distance-based query condition may be as follows:
select*from${tableName}where
ST_Contains(ST_GeomFromText('${geometryWkt}',${srid}),
${geomColumn})
when the query is based on the distance, the distance query of the map layer is to query the ground objects which are in accordance with the specified conditions within a certain range from the geometric object. For a point geometric object, inquiring a ground object in a circle with the point as the center of the circle and the distance as the radius; for line and plane geometric objects, a range of surface features on the object boundary is queried. For example, items within 100 kilometers of the query are queried, and the units of query distance are map units. And during distance query, whether the nearest ground feature is searched can be set through the isNearest parameter in the distance query parameter, the number of the nearest ground features to be searched is set through the expectCount parameter, and if the expectCount is not set, all ground features meeting the conditions can be searched. When the nearest ground object is searched, the distance tolerance value distance is invalid.
The key code involved in an SQL-based query may be as follows:
select*from${tableName}where${attributeFilter}
when the map is queried based on the SQL, the SQL query on the map is used for querying the ground objects meeting the SQL condition in the specified map layer. Query types in GIS can be generally classified into the following three types: simple attribute queries, simple spatial queries, and synthetic queries that are simultaneously related to spatial location and attributes. The SQL query refers to a query of which the condition is only related to the attribute of a spatial ground object and is not related to the geographic position of the ground object.
After the corresponding data are inquired according to the received inquiry conditions, the data can be displayed on the map in an aggregation mode. Specifically, different object types are defined according to different data types, such as point, linesting, polygon, marker, and the like; defining a feature object, wherein the feature object has geometry, style, property and the like; and hosting the feature object into the layer object for management, and finally rendering the feature object in the page by the map engine.
