GRL Missions

Mission Statement

GRL provides the warfighter and Nation with superior knowledge of the battlefield through innovative basic and applied research in geospatial and related sciences.

GRL conducts geospatial research, development, techhnology and evaluation of current and emerging geospatial technologies that will help characterize and measure phenomena within the physical (terrain) and social (cultural) environments encountered by the Army.

Service and Support

GRL is co-located with the Army Geospatial Center (AGC) and engages in research to support the development of the Army Geospatial Enterprise as well as develop geospatially-enabled technologies for the Army and Nation. GRL research areas and capabilities include terrain analysis and reasoning; passive and active spectral signature analysis; fluorescence; photogrammetry; terrain visualization; precision surveying and mapping; image analysis; data management; geographic information systems; data/image fusion; and spatio-temporal reasoning and numerical analysis. GRL focuses technical efforts in the following mission areas:

  • Terrain Analysis for Signal and Sensor Phenomenology
  • Geospatial Temporal Information Structure and Framework
  • GeoEnabled Mission Command
  • Geospatial Reasoning
  • Imagery and GeoData Sciences
