The Cultural Resource GIS Facility (CRGIS) is the only program within the National Park Service (NPS) dedicated to developing and fostering the use of geographic information systems (GIS) and global positioning systems (GPS) technologies in documenting, analyzing and managing cultural resources. For 20 years the mission of CRGIS has been to institutionalize GIS and GPS into the daily practice of cultural resource management by adapting these technologies to field surveys and inventory maintenance, as well as addressing links between cultural resource databases using locational information, all with the aim of increasing the effectiveness of cultural resource planning. Functioning inside and outside the NPS, CRGIS partners include other NPS programs and units, State/Tribal Historic Preservation Offices, local agencies, preservation organizations, universities and other Federal agencies. CRGIS provides a wide array of technical services and training as well in applying these technologies to specific cultural resource management projects.
