This data set contains vector polygons representing the quad boundaries of the 1:250,000 USGS topographic quadrangles. These boundaries represent the extent of the biological resources mapping for the North Slope, Alaska. Specifically, these data were used for the creation of the biology data compilation and edit maps. These data are also used for digitizing of hardcopy biology data that extended beyond the INDEX layer.This data set comprises a portion of the ESI data for North Slope, Alaska. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the INDEX (Index Polygons) data layer, part of the larger North Slope, Alaska ESI database, for additional boundary information.
