RGi publishes open source GPEP tool

Under the GRIDS II contract, RGi created an open source, lightweight geospatial performance enhancing proxy (GPEP) tool for cascading services that can be utilized in both a connected and disconnected environment. GPEP allows interoperability between systems by using the National System for Geospatial-Intelligence (NSG) standard while allowing a tactical operating center (TOC) to access map data even while in a disconnected state.

The RGi team utilized the Distributed Common Ground System-Army’s (DCGS-A) existing MapProxy software and added a user interface (UI) and geospatial standards that are NSG compliant. The new tool gives users the capability to download services locally and create NSG-compliant GeoPackages in a SQLite data format, which can then be loaded onto mobile handhelds, web tools and other mapping platforms.

RGi’s new GPEP tool will be distributed to both the Army Geospatial Center (AGC), as well as pushed back to DCGS-A. For more information, visit the project’s repository at
