[0021] The use of the present invention includes: GoogleEarth, Matlab, Matlab to GoogleEarth toolbox and other specific application examples of tool software are as follows. The above-mentioned software tools, other software and data capable of realizing the required functions of the present invention can all be used to support the realization of the present invention.
[0022] Google Earth provides free global satellite images and elevation data, and can update the terrain data of designated areas on the Internet at any time as needed. GoogleEarth supports kml files. Through the description of kml files, elements such as points, lines, and surfaces can be generated in the 3D terrain of GoogleEarth. The format description of the kml file can be found on the Internet http: / / www.opengeospatial.org / standards / kml / . If it is time-consuming to describe the 3D data by manually writing the kml file, third-party software can be used to generate the kml file. Typical of these is the Ma...
