Summary

Abstract: Prune is an application for viewing, editing and converting coordinate data from GPS systems. Basically it's a tool to let you play with your GPS data after you get home from your trip.

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.

Some example uses of Prune include cleaning up tracks by deleting wayward points - either recorded by error or by unintended detours. It can also be used to compare and combine tracks, convert to and from various formats, compress tracks, export data to Google Earth, or to analyse data to calculate distances, altitudes and so on.

Furthermore, Prune is able to display the tracks in 3d format (like the hike plots on this site) 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, Prune 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.

Prune is written in Java, so as long as your platform has a Java runtime (at least version 1.5) including GUI libraries then it should work. It was developed using eclipse and subversion on Linux, and has been tested on Linux (Mandriva 2009 and Debian Lenny with Sun JRE 1.6) and Windows XP (Home and Professional, with Sun JRE 1.5 and 1.6). It has also been shown to work on Mac OSX (Leopard, using the standard 1.5 JRE), Debian Lenny using the free OpenJDK JRE, Sun Solaris, Microsoft Vista and Microsoft 7. Any bug reports, feature requests, suggestions and improvements are welcome.

Currently Prune is at version 9 (since February 2010), but development of further features is ongoing and progress is given in the development page. Again, any help to improve it would be gratefully received. In particular any examples of data which is incorrectly parsed, and any updates to the translations offered would be very welcome (see the translation wiki). Prune is released under the Gnu GPL which specifies what you can do with the program and its source code.
