OpenJUMP is a community driven fork of JUMP the "Java Unified Mapping Platform" GIS software. The original JUMP was developed by Vivid Solutions, released under GPL2 in 2003 and discontinued in 2006. During 2004 already some enthusiastic developers joined together to enhance further the features of JUMP. They launched an independent development branch called OpenJUMP. The name gives credit to the original JUMP development, and at the same time describes the objectives of this project to be fully open to anyone wanting to contribute. These days OpenJUMP is developed and maintained by (some few) volunteers around the globe. If you need functionality or even better want to contribute you are very welcome to contact us at our mailing list.

A web based Geographic Metadata Catalog for data description and discovery. It implements international standards (e.g. ISO19115/19139, ISO19115-3, Z39.50, CSW 2.0, OGC). It originates from the United Nations and is used by many governments as geoportal software. This page is not maintained actively. Active development and discussion takes place on github. You can also connect directly with the companies supporting the development. Source code available on github https://github.com/geonetwork/

JGPSTrackEdit is a tool for editing gps tracks and planning (multiple days) tours (GPS track editor). An abritary number of tracks may be opened or created, tracks may be merged. A track may be splitted, reversed or edited (e.g. compressed and corrected). Points may be inserted or appended to a track (routing supported) or may be moved or deleted from a track. Maps of several providers are available, the default map is OpenStreetMap. Currently supported track formats: Garmin gpx route, Garmin gpx track, Garmin tcx, kml and plain txt. JGPSTrackEdit my also be used to download tile images for later offline use by smartphone apps. JGPSTrackEdit is written in the java language. To run the software, a java runtime installation is required (may be obtained from https://www.java.com/de/download/ or https://openjdk.java.net/projects/jdk8/ or https://adoptopenjdk.net/) More information, including the user manual, may be found on the wiki pages (https://sourceforge.net/p/jgpst
