Geographic Information System

The Guam Coastal Management Program’s GIS Section is responsible for the development of mapping tools and products to assist planners, communities, and natural resource managers in addressing a wide range of land-use, socio-economic, and environmental issues.


The GIS Section functions as the de-facto State GIS Data warehouse for federal agencies working with the Government of Guam as well as for GIS data collected among Government of Guam Agencies.  The majority of the map and land use data repository is available to all Government of Guam agencies, private sector, and general public. The maps and data are used for a variety of purposes that includes, but is not limited to, land use planning, routing of government services, enforcement, environmental management, analysis of development impacts, and, emergency planning, response, and disaster recovery efforts.   The data inventory consist of  remotely sensed imagery in hardcopy paper and mylar maps, digital map, numerous GIS data layers, and aerial ortho-rectified photography.


The GIS Section is also the de-facto lead in the Government of Guam for the development and utilization of Geographic Information Systems and Global Positioning Systems (GIS/GPS) technology to improve land use planning, and planning in general, by improving the overall operational efficiency and effectiveness of government agencies.
