Embodiment Construction

[0044] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0045]It should be noted that, in the prior art, when converting the kml file and the dxf file to each other, only one reference point is selected for conversion, resulting in easy conversion errors. In view of this, the present invention divides the file to be converted into regions, and selects a reference point for each region for conversion, which overcomes the problem in the prior art that errors are prone to occur due to conversion by only one reference point, and can effectively enhance the kml file. The conversion effect of converting to and from dxf files.

Abstract

The invention provides a method and a system for performing converting between a KML file and a DXF file. The method comprises the following steps of: selecting a plurality of regions according to a preset shape and size in an image corresponding to a file to be converted, wherein, any region contains part of the surface features and landforms in the file to be converted, so that all the regions contain all the surface features and landforms in the file to be converted; for any area, selecting a preset number of target reference points in the area, using all the target reference points corresponding to the area to determine the corresponding target conversion rules, and using the target conversion rules to convert the coordinates of the area to obtain the converted file; the method and thesystem divide the files to be converted into regions, and selecting reference points for each region for converting, thereby overcoming the problem that errors easily occur due to converting only onereference point in the prior art, and effectively improving the conversion accuracy of converting between the KML files and the DXF files.

Description

technical field [0001] The present invention relates to the technical field of file format conversion, and more specifically, to a method and system for mutual conversion between a kml file and a dxf file. Background technique [0002] KML (Keyhole Markup Language, Keyhole Markup Language) was originally an XML-based markup language developed and maintained by Google's Keyhole Company, which uses XML syntax to describe geospatial data (such as points, lines, polygons, polygons, and models, etc.) ), suitable for collaboration and sharing of geographic information in the network environment. [0003] DXF is an AutoCAD (Drawing Interchange Format or Drawing Exchange Format) drawing exchange file. DXF is a CAD data file format developed by Autodesk for CAD data exchange between AutoCAD and other software. Since AutoCAD is now the most popular CAD system, DXF is also widely used, becoming the de facto standard. Most CAD systems can read or export DXF files. [0004] Since the...
