GPS Utility by Alan Murphy is an easy-to-use application that provides management and manipulation of GPS information. You can use it to transfer data to/from a GPS receiver and store the data in PC files in one of several text formats.
The program converts between different map datums and many coordinate formats (Lat/Long, UTM/UPS, country grids etc.). Information can be filtered in various ways and waypoints sorted according to specified criteria. Using a scanned in bitmap you can digitize waypoints, routes and tracks. Route and track statistics are available and can be transferred into other programs for ananlysis (i.e. spreadsheet programs). You can plot your GPS information as a map and add map annotations in text or image form.
Please feel free to try out GPS Utility, but remember that the Freeware version has limited capacity (100 waypoints, 500 trackpoints, 5 routes). The registered version can deal with files containing up to 65,000 waypoints or 65,000 trackpoints and provides a number of advanced facilities. For more info, see the author's REGISTRATION page.
