Method of importing CAD (computer-aided design) graph and attribute data into GIS (Geographic information system)

Abstract

The invention discloses a method of importing a CAD (computer-aided design) graph and attribute data into a GIS (Geographic information system). The method comprises the following steps: I, importing a mining engineering planar graph: 101, storing in different layers, 102, naming the layers, and 103, importing the mining engineering planar graph to the GIS system; II, importing attribute data: before importing the attribute data, storing the attribute data of the mining engineering planar graph in a data sheet form and generating an attribute data sheet, wherein the attribute data through the following importing processes: 201, recognizing the attribute data, and 202, importing the attribute data to the GIS system; and III, synchronously displaying the attribute data and the Auto CAD graph. The method provided by the invention is rational in design, simple in importing step, good in use effect and high in practical value, and can be used for effectively solving the problems that the existing mining engineering planar graph cannot correlate with the attribute data in the graph after being imported to the GIS system, the operation step is complex, third-party software is utilized, and the use effect is bad.

Description

technical field [0001] The invention belongs to the technical field of coal mine excavation engineering plan processing drawn by AutoCAD software, and in particular relates to a method for importing CAD graphics and attribute data into a GIS system. Background technique [0002] The mining supervision and management system built by the land and resources management department needs to measure and map the mining conditions of mining enterprises such as roadways and goafs, so as to realize the supervision of the mining conditions of mining enterprises. Mining judgment, quantitative analysis, etc. However, at present, the professional mine surveying team of the land and resources management department or a third-party professional mine surveying team generally use theodolite, total station, level, rangefinder, topographic mapping instrument, gyro theodolite, suspension compass, geological compass, Laser pointing instrument, GPS, gradient gauge, measuring rope, various steel ru...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method for importing CAD graphics and attribute data into the GIS system in view of the deficiencies in the above-mentioned prior art. Effectively solve the problems that the existing excavation engineering plan cannot be associated with the attribute data in the map after being imported into the GIS system, the operation steps are complicated, third-party software is required, and the use effect is poor.
