[0044] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] Through CAD software, users can easily modify and edit drawings, such as adding, deleting, moving, rotating, scaling objects, etc., and can also adjust properties such as layers, colors, and line types. However, since the files generated by CAD drawings are too large, if the CAD files are sent directly, the sending time will be too long, and there are also security issues with the files. The other party also needs to spend a lot of time to open the files, so it is necessary to convert the CAD files into GeoJson format; but CAD files cannot be directly converted into Geojson files, so a method for automatically processing map data conversion is needed.

[0046] The automatic processing method for map data conversion described in the preferred embodiment of the present invention is as follows: Figure 1 As shown, the automatic processing method for map data conversion includes the following steps:

[0047] Step S10: obtaining an initial file, initializing the initial file and saving it, to obtain a file in a first format and a saving path.

[0048] First, use the data conversion tool to perform initial conversion on the acquired initial file (CAD file). Here we need to use GDAL (Geospatial Data Abstraction Library, an open source raster spatial data conversion library under the X / MIT license agreement), and use the abstract data model to output various file formats. This function is implemented through a series of command line tools.

[0049] Specifically, an initial file is obtained, and the initial file is initialized using a connected data conversion library to obtain a file in a first format; the file in the first format is stored to obtain a saving path of the file in the first format.

[0050] Among them, the acquired initial file is initially converted through the data conversion library to obtain a CAD file in the dwg format (i.e., the file in the first format), thereby improving the flexibility of subsequent conversion of the initial CAD file, reducing the time of subsequent file conversion, and thus improving the efficiency of file conversion.

[0051] Step S20: according to the saving path, load the file in the first format into the conversion tool, output the target file after the format conversion, and obtain the source layer of the initial file.

[0052] Among them, after the initial CAD file is initially converted, the corresponding conversion file is found through the save path and converted again, and finally a dxf file (target file) that can be used for layer operations is obtained, and the source layer of the initial first format file is obtained at the same time.

[0053] Specifically, the file in the first format is loaded into the conversion tool through the save path, and the target file output by the conversion tool is obtained; wherein the conversion tool determines the file format of the target file according to the save path, and constructs the target file according to the file format; obtains multiple source data features of the initial file, and obtains the source layer of the initial file based on all the source data features.

[0054] Among them, through the initial save path of the CAD file, the CAD file in the dwg format (i.e., the file in the first format) is found, and a function (such as LoadOptions, a function used to define asynchronous loading option data) is used to load the CAD file in the dwg format into the abstract data model, and a CAD graphics processing control (i.e., CADImage) is used to create a corresponding object of the Image subclass and save it as a dxf file (target file), and then output through the abstract data model and saved to obtain the corresponding save path; at the same time, the basic data source of the geographic data in the initial file is obtained, and the source layer is constructed based on these basic data sources.

[0055] Furthermore, a projection coordinate system is constructed, and a coordinate point is randomly set in the source layer as an origin; based on the origin, the source layer is projected into the projection coordinate system.

[0056] Among them, since the CAD file has no coordinate system, it is necessary to randomly set a coordinate origin in the source layer, so as to use it as a control point for map alignment and improve the accuracy of map data conversion.

[0057] Step S30, traverse all the geometric data in the source layer, use a preset function to convert all the geometric data to obtain target geometric data, export the target geometric data in a second format, and assign it to the vector layer of the target file.

[0058] The data in the source layer is converted to the newly created vector layer through coordinate system registration, thereby realizing the conversion of the CAD file.

[0059] Specifically, all the geometric data in the source layer are traversed, and multiple spatial attribute features of the initial file are obtained according to all the geometric data; each of the spatial attribute features is converted to obtain a corresponding target spatial attribute feature; according to the number of the geometric data, a corresponding number of target geometric data are constructed, and the corresponding target spatial attribute features are assigned to the corresponding target geometric data; all the target geometric data are exported in a second format using a data conversion library; a vector layer of the target file is created, and according to the source layer in the projection coordinate system, all the target geometric data are assigned to the new vector layer.

[0060] Among them, Figure 2 As shown, firstly, the geometric data in the source layer is traversed to obtain the spatial attributes of the geometric data (for example, point, line and surface), and these spatial attributes are converted into coordinates with data characteristics. The converted coordinates should be in the format of [longitude, latitude] ([longitude information, latitude information]), which complies with the GeoJSON specification; then, the target geometric data of the corresponding data is constructed, and the geometric function (for example, Geometry.CreateFromJson function) is used to assign the converted coordinates to the target geometric data, and it is exported in json format and assigned to the vector layer created according to the target file. This process is achieved by transferring the attributes of the projection coordinate system, which improves the accuracy of the assignment, thereby improving the accuracy of the final map data conversion.

[0061] Furthermore, the horizontal coordinate of the target geometric data is the longitude information of the corresponding target spatial attribute feature, and the vertical coordinate of the target geometric data is the dimension information of the corresponding target spatial attribute feature.

[0062] The creation of the vector layer is achieved through the following code:

[0063] using ESRI.ArcGIS.Carto;

[0064] using ESRI.ArcGIS.Geometry;

[0065] using ESRI.ArcGIS.Geodatabase;

[0066] Assume that axMapControl is the map control and sdeWorkspaceFactory is the SDE workspace factory:

[0067] IMap pMap=axMapControl.Map;

[0068] IWorkspace pWorkspace;

[0069] IFeatureLayer pFeatureLayer;

[0070] IFeatureClass pFeatureClass;

[0071] Set the SDE connection properties:

[0072] sdeWorkspaceFactory.ConnectionProperties=["server=myServer;

[0073] instance=myInstance; user=myUsername; password=myPassword;

[0074] version = mySdeVersion"];

[0075] Open the SDE workspace:

[0076] pWorkspace=sdeWorkspaceFactory.Open(featureDatasetName,0);

[0077] Open the feature class;

[0078] pFeatureClass=

[0079] pWorkspace.OpenFeatureClass(featureClassName);

[0080] Create a new feature layer:

[0081] pFeatureLayer=new FeatureLayerClass();

[0082] pFeatureLayer.FeatureClass=pFeatureClass;

[0083] pFeatureLayer.Name=pFeatureClass.AliasName;

[0084] Add to map:

[0085] pMap.AddLayer(pFeatureLayer);

[0086] axMapControl.ActiveView.Refresh().

[0087] Step S40: Obtain the export attributes and target path set by the user, and use a driving tool to export the target geometric data in the vector layer to the target path according to the export attributes.

[0088] The derived attributes include: point feature attributes, line feature attributes and surface feature attributes, and the target geometric data includes: point feature data, line feature data and surface feature data.

[0089] Specifically, the point feature attributes, the line feature attributes or the surface feature attributes input by the user are obtained, and the target path set by the user is obtained; according to the point feature attributes, the line feature attributes or the surface feature attributes input by the user, the point feature data, the line feature data or the surface feature data in the vector layer are integrated to obtain a target file, and the target file is exported to the target path.

[0090] Among them, after the final conversion of the CAD file is completed (that is, converted to Geojson format), the export properties of the file are set according to the user (that is, the type of features that the user needs to export):

[0091] exported_properties=['id','name','type','timestamp','area'];

[0092] Then the corresponding feature type is exported as a Geojson file (target file), and the storage path of the exported file (i.e., the target path) is output, finally realizing the process of converting the initial CAD file into a Geojson file, realizing the automatic conversion of map data, reducing the time required to wait for data conversion during the development process, and improving the user's work efficiency and usage experience.

[0093] The present invention initializes the map data, assigns the relevant data to the newly constructed vector layer with the projection coordinate system as the medium, and exports it in the target format, thereby realizing the automatic conversion of the map data and improving the convenience of the automatic conversion of the map data.

[0094] Furthermore, if Figure 3 As shown, based on the above-mentioned automatic processing method for map data conversion, the present invention also provides an automatic processing system for map data conversion, wherein the automatic processing system for map data conversion includes:

[0095] The file preprocessing module 51 is used to obtain an initial file, perform initialization processing on the initial file and save it to obtain a file in a first format and a saving path;

[0096] The layer acquisition module 52 is used to load the file in the first format into the conversion tool according to the saving path, output the target file after the format conversion, and obtain the source layer of the initial file;

[0098] The layer export module 54 is used to obtain the export properties and target path set by the user, and use the driving tool to export the target geometric data in the vector layer to the target path according to the export properties.

[0099] Furthermore, if Figure 4 As shown, based on the above-mentioned automatic processing method and system for map data conversion, the present invention also provides a terminal accordingly, and the terminal includes a processor 10, a memory 20 and a display 30.
