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 JUMP DB Query Plugin is an extension for the OpenJUMP GIS platform that allows OpenJUMP users to give arbitrary database queries to retrieve and display geographic feature sets.
Spatial databases currently supported are
PostGIS, Oracle Spatial, MySQL, and SpatiaLite.
TeNeM (Telecommunications Network Model) is a PostgreSQL schema with PL/pgSQL functions and triggers intended to make with a fiber optic network management. It is also a GIS JUMP plug-in to edit and visualize the data. PostGIS is used to extend Postgre.
