Tool to grab and save to disk in jpeg very large (any!) part and zome of Google Earth map in maximal resolution. GoogleEarth COM API used, GoogleEarth must be installed. To seamless compose of resulting jpeg images convert it to tiff, use GEOTIFF_TFW_FileGenerator.rar (or other tfw generator) and join images, for example, with MrSID. I m really grab with this tools big part of Russia (millions fo square km). Enjoy.(Tool to grab and save to disk in jpeg very large (any!) Part and zome of Google Earth map in maximal resolution.
