How to download terrain maps from Google Maps, and to view them afterward? AllSoft has created this program to solve these problems. It is very easy to use, just enter a new name project, for instance, “exemple.gmtd”. All the folders will be recorded to *. gmtd. If you would like to continue an old project, just click “To open project”button. There are 4 parameters (Left Longitude, Right Longitude, High Latitude, Low latitude) to define the image zone you would like to download. Zoome mode allows you to define the image accuracy. You can define the number of sequence you would like to download and start downloading. The downloaded images will be saved to BMP format, but it is possible to convert them to fit your needs.
