drg2gtm is a simple C-Progam which reads a USGS DRG images and their corresponding worldfiles. The image is inserted into a new GSP Track Maker file and automatically registered.
Why was it developed?
Manually registering DRGs from the USGS and the Microsoft Terraserver was tedious. I wanted a way to do this automatically.
