GPSCon is a ncurses-based GPS mapping program.

It works quite well if you have a spare NMEA-0183 compatible GPS device. GPSCon is also capable of reading data files containing points of interest, which enables you to create text-based maps of your area.

In the past, I have used GPSCon for Geocaching. Currently, the project is dormant, though.
