The vegetation of the Kuparuk River watershed was mapped for several US National Science Foundation projects, including the Arctic System Science Flux Study and the Long-Term Ecological Research program (Muller et al. 1998).
The Kuparuk Basin map is a raster (tif) map, with 50-m pixels, and 8 land cover categories. The boundaries of the map form a rectangle that encompasses the entire Kuparuk River watershed, from the headwaters on the north side of the Brooks Range to the Beaufort Sea coast.
The map is based on a modified unsupervised classification of a portion of a Landsat Multispectral Scanner (MSS) composite created by the National Mapping Division, U.S. Geological Survey EROS data center, Anchorage, Alaska. Geobotanical maps and earlier Landsat-derived maps of the region were used for supplementary information to interpret the spectral classes.
