It's an easy, one-step process to convert any shapefile (.shp) to GPX with ExpertGPS Pro. Take any GIS layer and create GPX files from your shapefiles that you can send to any GPS receiver, share with clients, or publish online.
The best way to convert ESRI's .shp format to GPX is to Import your Shapefile into ExpertGPS mapping software, using Import on the File menu. ExpertGPS Pro automatically reprojects your shapefile from UTM, state plane coordinates, or any other projection into GPX's native format (latitude and longitude in decimal degreees, in WGS84 datum). ExpertGPS isn't just a GPX converter - it's a great utility for editing your converted shapefiles, assigning waypoint symbols, and editing GPX files.
ExpertGPS is 100% compatible with GPX, the GPS Exchange Format. It uses GPX as its native file format, and you can copy and paste GPX directly between ExpertGPS and any other GPX-enabled application. ExpertGPS was written by TopoGrafix, the maintainers of the GPX Standard, so you know you're getting a proven SHP to GPX converter.
