Detailed Description
The applicant previously filed a patent entitled "a method for converting from a CAD planar coordinate system to the WGS84 coordinate system of google maps". This patent relates to the coordinate conversion of electric power cable for some information is more general, still need to judge the rationality of cable layout after the coordinate conversion finishes, and the switching system does not have help to the judgement in later stage, and it is very inconvenient if the design is unreasonable still need to convert again.
In view of the above, the invention provides a coordinate system conversion method with geological condition switching for a power pipeline, which is arranged in a coordinate conversion system, wherein the system comprises a CAD analysis module, a layer extraction module, a coordinate conversion module, an output module and a Google map drawing module, and the CAD analysis module is used for loading a CAD file to obtain all surface area layers; the layer extraction module is used for selecting a surface area layer to be processed and converting all surface areas in the selected surface area layer into a point set; the coordinate conversion module is used for circularly traversing point coordinates of a plane coordinate system in the point set and obtaining WGS84 coordinate system coordinates supported by the Google map through a conversion method; the output module is used for outputting the converted WGS84 coordinate system point set to a file with a specified format; the google mapping module is used for reading the point of the WGS84 coordinate system in the output file, and further comprises a google earth module. Google Earth (GE) is a virtual Earth software developed by Google corporation that lays out satellite photos, aerial photos, and GIS on a three-dimensional model of the Earth. The geological information of the area can be easily acquired from the geological map, the geological map of the surface area map layer to be processed is acquired through the Google earth module, during processing, the geological boundary line and the terrain boundary line contained in the surface area map layer are respectively acquired, the terrain boundary line is used for verifying whether the position of the power pipeline is correct, and the situation that the map is mistakenly sleeved is avoided.

Thus, after the coordinate conversion is completed, the section of the power pipeline is analyzed and modified. Because geological materials in different geological layers are different, the same pipeline passes through too many geological layers, the problems of uneven aging and difficult uniform service life are easy to occur, and therefore the power pipeline is arranged in the same or similar geological layers as far as possible. The geological map is marked with a water-bearing stratum, and the electric power pipeline is independently marked with a passing mode at the position where the electric power pipeline passes through the water-bearing stratum. The geological boundary of the expected segment in the unit area range is set to 7 segments within 1 square kilometer.
