*One way of describing subsistence is with maps which show areas used for hunting, fishing, and gathering.

*Subsistence specialists utilize a wide range of historical information to document historical and traditional boundaries of subsistence use and users.

*Contemporary mapping methods have refined ways these specialists document subsistence use areas. The Geographic Information System (GIS) is a major tool used in mapping this dynamic social process.

*In 1887-88, the Tongass Resource Use Cooperative Survey (TRUCS) mapped subsistence use and users throughout southeast Alaska. TRUCS mapped 31 rural community use areas by quadrangle and specific resource.

*Computer mapping, as in TRUCS, has revolutionized the way specialists use “spacial data” for planning purposes, as well as how several maps are displayed simultaneously. It also shows how subsistence areas change through time; and how several community use areas may overlap.
