[0030] Figure 1 A flowchart of a data import and export method of a digital mapping system according to an embodiment of the present disclosure is schematically shown. Figure 1 As shown, an embodiment of the present disclosure provides a data import and export method for a digital mapping system, comprising: in response to receiving data sent by the digital mapping system, screening the data to obtain geological survey data; using field mapping relationships, importing the geological survey data; the data at least includes a compressed package and a geographic space coordinate system code; the geological survey data at least includes measured profile data and route survey data; in response to receiving a geological survey data request from the digital mapping system, exporting the geological survey data using field mapping relationships; wherein the field mapping relationship at least includes a target field in the digital mapping system and a corresponding mapping field.

[0031] Figure 7 The schematic diagram schematically shows the field mapping relationship according to the embodiment of the present disclosure. Figure 7 As shown, the target fields and corresponding mapping fields of the designed route data table in the route survey data are shown in the figure. Optionally, it also includes a measured profile acquisition data table of measured profile data, a measured profile traverse measurement data table, a measured profile stratification data table, a measured profile sampling data table, a measured profile occurrence data table, a measured profile photo data table, a measured profile fossil data table, a measured profile sketch data table, a measured profile geological point data table and a measured profile stratification thickness calculation data table; it also includes a route survey geological observation point acquisition data table, a route survey segmented route acquisition data table, a route survey point boundary acquisition data table, a route survey occurrence point acquisition data table, a route survey photo point acquisition data table, a route survey sampling data table, a route survey sketch point acquisition data table and a route survey fossil sample collection data table.

[0032] Through the embodiment of the present disclosure, the measured profile data file and route survey data file of the digital mapping system (RgMap system) are exported and the source data coordinate system EPSG code is passed in. Through a series of data processing, conversion and other operations, the field mapping relationship is used to realize the storage operation of the measured profile data and route survey data. And the measured profile data and route survey data are exported to a format that can be recognized by RgMap. That is, through the screening function, it is ensured that only effective and necessary geological survey data are imported into the system to avoid excessive system load or data redundancy. By using the predefined field mapping relationship, it can be ensured that data of different data formats or sources can be uniformly imported into the digital mapping system, and finally the measured profile data and route survey data between RgMap and GIS system are imported and exported. It provides great convenience for realizing how to display the stock data of the digital mapping system (RgMap) in the GIS system and how to display the newly added data in the GIS system in the digital mapping system (RgMap). It can further improve the efficiency and accuracy of digital regional geological survey work and provide more powerful support for the exploration, development and utilization of geological resources.

[0033] Among them, the EPSG code (EPSG Code) refers to a standardized numbering system developed by EPSG (European Petroleum Survey Group) to represent different geographic coordinate systems, projection systems, geographic coordinate reference systems (CRS) and related parameters. Each EPSG code represents a specific geographic coordinate reference system (such as WGS 84, UTM, etc.) or projection system, providing a unified way to identify and share coordinate reference information of geographic data. The EPSG code is a digital number, such as: 4326, 3857, etc. Each number corresponds to a specific geographic coordinate system, projection method or other related spatial data standards. The EPSG code is not only used to identify the coordinate system, but also includes information such as projection method, ellipsoid, coordinate axis direction, etc.

[0034] On the basis of the above embodiment, the geological survey data is imported by utilizing the field mapping relationship, including: obtaining the data of the target field from the geological survey data according to the target field; and converting and obtaining the data of the mapping field for importing into the target field according to the field mapping relationship and the data of the target field.

Parse the measured profile SQLite format source data, and obtain the required measured profile data through the program's built-in database table and field mapping relationship. Obtain the attachment resources corresponding to each measured profile photo point data and each measured profile sketch data through the attachment (picture, sketch) encoding rules. According to the starting point coordinates, rotation azimuth, slope distance, slope angle, and elevation of the measured profile acquisition data, calculate the starting point and end point coordinates and elevation of each wire in the measured profile wire measurement data. According to the EPSG code passed in, the measured profile traverse data, measured profile layering data, measured profile sampling data, measured profile occurrence data, measured profile photo data, measured profile fossil data, and measured profile sketch data are converted to 4326 coordinate system for display in this system. Source data and sketch resources are stored in the library.

[0037] Figure 3 The flowchart of importing route survey data according to the embodiment of the present disclosure is schematically shown, specifically including importing route survey data. The import is mainly divided into the following steps: upload a compressed package and pass in the EPSG code of the source data coordinate system, and the program determines whether the compressed package format is correct. Parse the compressed package and filter the required data (source data, attachment resources).
