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.

GeoServer is an open-source software server written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. Being a community-driven project, GeoServer is developed, tested, and supported by a diverse group of individuals and organizations from around the world. GeoServer is the reference implementation of the Open Geospatial Consortium (OGC) Web Feature Service (WFS) and Web Coverage Service (WCS) standards, as well as a high-performance certified compliant Web Map Service (WMS), compliant Catalog Service for the Web (CSW) and implementing Web Processing Service (WPS). GeoServer forms a core component of the Geospatial Web.

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

OpenSeaMap's goal is to add nautical and tourism information a sailor could be interested in to OSM (OpenStreetMap) and to present it in a pleasing way. Those include beacons, buoys and other seamark and port information.

A web based Metadata Catalog Server for data description and discovery. Supports both generic and geospatial data discovery. It implements international standards (e.g. ISO19115/19139/19119, ISO19115-3, DCAT-AP, CSW 2.0, OGC API Records). It originates from the United Nations and is used by many governments as geoportal software. Active development and discussion takes place on GitHub and OSGeo Discourse. You can also connect directly with the companies supporting the development. Source code available on github https://github.com/geonetwork/

EasyGeo is an open source cartography program that generates maps using explicit equations in the choice of parameters. The input data is point data (not lines or areas) using csv files with object names (cities), variables (e.g. birth rate) and x and y coordinates. It is also possible to import maps in GeoJSON format. Possible output maps are: proportional circles, colour classes and interaction potential functions (Gravity models). Test data (10 countries and associated data) is provided with the program and located in the installation directory A user manual is also provided.
