Minnesota Land Cover 1991-92: Map

GAP map from DNR

This printed poster-size map depicts classes of vegetative land cover as derived from 1991-92 satellite imagery. See below for ordering information.

The map was created by the Resource Assessment Unit of the Minnesota Department of Natural Resources and is a derivative product of the federal Gap Analysis Program (GAP), a nationwide effort to prioritize and focus conservation work. The GAP vegetation project is the first to use satellite images to map Minnesota vegetation community types at the 1-acre level of detail while employing a uniform statewide analysis protocol and vegetation typology. The map also describes and shows the boundaries of Ecological Classification System sections.

Land cover classes

The detailed computer database* on which the map is based contains 49 classes of vegetation in mapping units as small as 1 acre. For display at the map scale (1:563,200), the classes have been condensed to 11, and the smallest vegetation unit shown is about 5 acres. The state's total area is about 54 million acres.

Specifications and ordering information
