GpsPrune is a map-based application for viewing, editing and converting coordinate data from GPS systems.
It can load data from arbitrary text-based formats (for example, any tab-separated or comma-separated file) or Xml, or directly from a GPS receiver. It can display the data (as map view using openstreetmap images and as altitude profile), edit this data (for example delete points and ranges, sort waypoints, compress tracks), and save the data (in various text-based formats). It can also export data as a Gpx file, or as Kml/Kmz for import into Google Earth, or send it to a GPS receiver.
GpsPrune can display the tracks in 3d format and lets you spin the model round to look at it from various directions. You can also export the model in POV format so that you can render a nice picture using Povray. You can also create charts of altitudes or speeds. It can also load Jpegs and read their coordinates from the exif tags, and export thumbnails of these photos to Kmz format so that they appear as popups in Google Earth. If your photos don’t have coordinates yet, GpsPrune can be used to connect them (either manually or automatically using the photo timestamps) to data points, and write these coordinates into the exif tags.
This is free and open source software.
Key Features
- Loading of coordinate data from file in any text-based format, with any combination of fields and any separator, or in GPX or KML or KMZ or NMEA or GeoJSON format. Xml files can be zipped or gzipped. Files can be directly loaded from a cable-connected GPS receiver.
- Importing of huge variety of device-specific formats using GPSBabel.
- Top-down, zoomable, draggable view of data points including map images from Openstreetmap or any similar map tile server (eg OpenTopoMap, Ordnance Survey, Öpnv, …).
- Caching of map tiles to disk for faster access and offline use.
- Altitude profile view or speed profile view.
- Selection of individual points and ranges to show details.
- Deletion of duplicates and variable compression of track.
- Deletion of selected points and ranges, and reversal of ranges.
- Editing of point data, and creation of tracks and waypoints.
- Drawing of new tracks, and dragging points to reposition them.
- Re-ordering of waypoints within data set.
- Saving of data in specified text format, XML format (GPX, KML, KMZ) or sending to GPS receiver.
- Interactive 3d display of data, including map and/or terrain.
- Export to POV format for rendering of 3d model by Povray.
- Loading of photos in jpeg format with or without coordinate data in exif tags.
- Connection of photos to points, and saving of coordinates in exif tags. (requires exiftool)
- Automatic correlation of photos with track points using each photo’s timestamp.
- Inclusion of photo thumbnails in KMZ export.
- Loading, playing and correlation of audio files (such as wav, mp3, ogg) in the same way as photos.
- Generation of charts (eg altitudes, speeds) either on screen or exported to SVG file.
