Fountain Computer offers a variety Geographic Information Systems tools and software. Here is a list of the programs that are currently available:

• GTFViewer. This programs allows you to view GeoTiff files. GeoTiff files are available from the USGS and they generally contain maps or aerial photographs. GeoTiff images are often very large and the GTFViewer has special features that allow you trim, resize and print these images. The Viewer can also measure distances and surface area with images.
