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.
