GpsPrune is a desktop application for viewing, editing and converting GPS coordinate data. It can be used after a walk, ride or other journey to inspect a recorded track, remove unwanted points, correct positions, add waypoints or prepare the data for another application or GPS receiver.
The program accepts structured GPS formats as well as arbitrary text data containing coordinate fields. Map and profile views make recorded journeys easier to understand, while its photo and audio tools can associate media with positions along a track. GPSBabel can be used alongside GpsPrune when data must be imported from proprietary device formats.
This is free and open source software.
Key Features
- Loads GPX, KML, KMZ, NMEA, GeoJSON and configurable text-based coordinate files.
- Displays tracks and waypoints over online map tiles with local caching for later use.
- Shows altitude and speed profiles alongside the map view.
- Creates tracks and waypoints and lets users drag individual points to new positions.
- Deletes unwanted points or ranges, reverses track sections and removes duplicate data.
- Provides variable track compression to reduce the number of recorded points.
- Imports additional GPS formats through GPSBabel and can transfer data to supported receivers.
- Offers an interactive three-dimensional view of tracks and terrain.
- Loads JPEG photographs and reads geographical information from EXIF metadata.
- Can correlate photographs with track points using timestamps and write coordinates back to EXIF data.
- Associates audio recordings with track positions in a similar way to photographs.
- Exports charts showing information such as altitude and speed.
- Includes multiple undo operations for editing GPS data.
- Cross-platform support – runs on Linux, macOS, and Windows.
