Technical Field
The invention relates to a method for publishing a CAD file into an electronic map.
Background
In the prior art, related tool software is used for secondary development, a CAD file is converted into a layered map, but the method is limited by the functions of the tool software, only SHP is exported, and the original style is lost. Or a manual extraction method, but this may result in the map not being completely consistent with the original map, and the efficiency is relatively low.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: in order to overcome the defects of the prior art, a method for publishing a CAD file into an electronic map is provided.
The technical scheme adopted by the invention for solving the technical problems is as follows: a method for publishing a CAD file into an electronic map comprises the following steps:
1) analyzing the CAD file in the DWG format, extracting and generating an SHP vector file of a surface, a line, a point and a mark, and correspondingly generating an SLD file;
2) analyzing the inclusion relationship of the planes in the information to form a hierarchical relationship;
3) and generating each layer by using the GeoServer through acquiring the SHP vector file and the corresponding SLD style file, and generating a layer group according to the hierarchical relation to externally form a map interface for front-end calling and displaying.
Preferably, in step 1), all lines are an SHP vector file, where each line generates an ID, and the attributes of each line are defined in the SLD file, where the attributes include width, style, and color.
Preferably, in step 1), all the points are an SHP vector file, where each point generates an ID, and the attributes of each point are defined in the SLD file, where the attributes include style and color.
Preferably, in step 1), all the tags are an SHP vector file, wherein each tag generates an ID, and the attributes of each tag, including size, color and font, are defined in the SLD file.
Preferably, in step 2), a pattern is located below the pattern in which it is contained, wherein lines are located above the surface, dots are located above all lines, and marks are located above the dots, lines, and surface.
The method for publishing the CAD file into the electronic map has the advantages that the CAD file is analyzed, a plurality of SHP vector files and corresponding SLD style files are generated, the SHP vector files and the SLD style files are overlaid according to the hierarchical relationship and are published into the map, and the published map can be guaranteed to be consistent with the original map.
Detailed Description
Example (b):
a method for publishing a CAD file into an electronic map comprises the following steps:
1) analyzing the CAD file in the DWG format, extracting and generating an SHP vector file of a surface, a line, a point and a mark, and correspondingly generating an SLD file;
2) analyzing the inclusion relationship of the planes in the information to form a hierarchical relationship;
here, the hierarchical relationship of a face to a face, a graphic is below the graphic that it is contained in, i.e., the contained graphic overlays the contained graphic, thereby ensuring that the graphic is not overlaid.
3) And generating each layer by using the GeoServer through acquiring the SHP vector file and the corresponding SLD style file, and generating a layer group according to the hierarchical relation to externally form a map interface for front-end calling and displaying.
The hierarchical data can be read through the REST interface, and the data are overlaid to form a layer for distribution.
Preferably, in step 1), all lines are an SHP vector file, where each line generates an ID, and the attributes of each line are defined in the SLD file, where the attributes include width, style, and color.
Preferably, in step 1), all the points are an SHP vector file, where each point generates an ID, and the attributes of each point are defined in the SLD file, where the attributes include style and color.
Preferably, in step 1), all the tags are an SHP vector file, wherein each tag generates an ID, and the attributes of each tag, including size, color and font, are defined in the SLD file.
Preferably, in step 2), a pattern is located below the pattern in which it is contained, wherein lines are located above the surface, dots are located above all lines, and marks are located above the dots, lines, and surface.
Compared with the prior art, the method for publishing the CAD file into the electronic map analyzes the CAD file, generates a plurality of SHP vector files and corresponding SLD style files, superposes the SHP vector files and the SLD style files according to the hierarchical relationship, and publishes the SHP vector files into the map, so that the published map can be ensured to be consistent with the original map.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
