Commercial Joint Mapping Toolkit

The Commercial Joint Mapping Toolkit, or CJMTK (also referred to as C/JMTK), is a replacement for the previous United States Department of Defense (DoD) Joint Mapping Toolkit (JMTK) that utilizes commercial off-the-shelf (COTS) components. The primary component of CJMTK is ESRI's complete ArcGIS system, with additional functionality for military analysis, overlays, sensors, and data. CJTMK is now the DoD standard mapping toolkit for C2I software.

Organizations creating C2I software for the DoD can obtain, develop on, and deploy to the DoD the CJMTK package free of charge. Non-C2I DoD programs may use the CJMTK under the Extended User Community (EUC) licensing option, for which the EUC program is responsible for the funding. Programs outside the DoD may be eligible to use the CJMTK under the Foreign Military Sales (FMS) licensing option. FMS certification and funding are the responsibility of the sponsoring organization.

The CJMTK API is available in the form of Microsoft COM, C, C++ and Java. CJMTK supports most common geospatial data formats and protocols (see the CJMTK and ESRI sites for specifics), including, with the latest version, Google Earth's KML format.

The current version of CJMTK is 9.3, released in July 2008.
