The foundation of The JUMP-Project is a suite of free, open-source applications that provide an extensible API and graphic user interface (GUI) for viewing and manipulating spatial data-sets. Currently, the major projects of the JUMP Project suite include:

The JUMP Unified Mapping Platform (JUMP) provides both the main UI and an API to a highly extensible framework for developing and running custom spatial data processing applications.

The JTS Topology Suite (JTS) provides an API of 2D spatial predicates and functions for fundamental geometric operations in an OGC-compliant spatial object model.

The JCS Conflation Suite (JSC) is an API and a set of interactive tools which perform conflation on spatial datasets.
JUMP Plug-Ins optimize the JUMP component tools and functions into enviroments specific to the needs of a given project or application. For example, the Government of British Columbia's (BC) Ministry of Sustainable Resource Management (MSRM) has developed and used various custom JUMP plug-ins for the preparation and integration of data into their Corporate Watershed Base (CWB) project.
