The Anchorage Regional Office Geographic Information System (GIS) staff selected 57 Intensive Mapping Units (IMU) (or Areas, IMA) in Wrangell-St. Elias National Park & Preserve to be mapped using infrared aerial photographs and aerial surveys. This data was used to create a land cover map for the park. Each IMU has a number of polygons (from 10 to 45) which were identified on the aerial photographs and for which data were collected during 1989, 1991 and 1992 field seasons. The FIREPRO ground truth data collected from 1980 to 1988 was used as an ancillary data set for this land cover mapping. Accession No. WRST-00183.
