Army Geospatial Center The Army Geospatial Center ( AGC ) ( formerly Topographic Engineering Center ( TEC ) ) is a Major Subordinate Command of the United States Army Corps of Engineers . It is located in Alexandria , Virginia , within the Humphreys Engineering Center adjacent to the Fort Belvoir military reservation . The AGC reportedly coordinates , integrates , and synchronizes geospatial information and standards across the Army , develops and fields geospatial enterprise - enabled systems and capabilities to the Army and the Department of Defense , and provides direct geospatial support and products to Warfighters . Its Geospatial Research and Engineering Division , an Engineer Research and Development Center asset , conducts research and development into geospatial data collection , processing , exploitation , and dissemination in support of both civilian missions and missions of U . S . ground forces . Subject matter expertise . AGC reportedly employs a workforce of more than 400 , which includes Department of Defense civilians , contractors and military personnel . They support four program areas in support of the AGC mission : The AGC Director serves as the Geospatial Information Officer of the US Army . Terrain data . AGC ' s primary area of expertise is in acquiring and depicting terrain data . It has developed products to rapidly characterize complex and urban terrain that include the use of the Rapid Terrain Visualization ( RTV ) and Urban Recon ( UR ) Advanced Concept Technology Demonstrations ( ACTDs ) . These are embodied in the BuckEye program , bringing the collection of high resolution color imagery and coincidentally collected Light Detection and Ranging ( LIDAR ) data to the battlefield , enabling the rapid characterization of complex and urban terrain at a human scale . Typically , the BuckEye program collects 1m post spacing terrain data ( derived from LIDAR ) coincidentally collected with 10 cm color imagery . BuckEye data products are reportedly unclassified and for sharing with US military allies . BuckEye was first deployed operationally in Iraq in 2004 , under Operation Iraqi Freedom , on rotary - wing aircraft . BuckEye was subsequently flown over all of Iraq ’ s urban areas and transportation corridors , constituting some 11 % of the Iraqi landmass , using fixed - wing aircraft . BuckEye was first deployed operationally in Afghanistan in 2006 , under Operation Enduring Freedom , on rotary - wing aircraft . By 2008 , BuckEye was being consistently flown fixed - wing over Afghanistan . With the surge in forces beginning in 2009 , multiple BuckEye fixed - wing and unmanned aircraft systems ( UAS ) platforms have been deployed in Afghanistan to gather human - scale terrain data for use by Coalition commanders and host nation forces . The BuckEye program was recognized as a 2006 Army " Greatest Invention of the Year . " Other areas of expertise . The other reported types of products and services that AGC provides include : Publications . AGC reports originating a series of Army Engineer Manuals and technical publications on the following topics . The engineer manuals cover the following : photogrammetric mapping , NAVSTAR GPS positioning surveying , deformation monitoring and control surveying , topographic surveying , and hydrographic surveying . Other technical publications cover geographic profiling , terrain gap identification and analysis , coastal boundary and merging bathymetry , comparison of digital flood insurance rate maps to interferometric synthetic aperture radar ( IFSAR ) products , and the effect of " El Niño " on Army tactical decision aids , among other topics .
