GIS is an important decision making tool in the ACG.

The ACG's Geographic Information System (GIS) is utilized for the creation, storage, processing, analysis and maintenance of data bases and georeferenced maps. This spatial data is an integral tool in the planning, management, conservation, protection, and restoration of the ACG's biodiversity and sites of cultural importance.

GIS is also applied to the management and monitoring of the region's natural resources through the design and elaboration of data bases and maps of land ownership, state-owned natural heritage sites, registered property boundaries, tourist maps, and the ACG Management Plan, among others. The consolidation of a single block of protected area that is so integral to  the ACG is made possible through the use of GIS to keep an accurate, georeferenced, and up to date record of property rights that is monitored on the ground and in the land registry office.  

The ACG's GIS department also collaborates with other ACG programs for their spatial data and map needs such as zonification of tourist areas or classification of forest types as well as training ACG staff in basic cartography and GPS use.
