Mapping Data of Polar Bear Maternal Den Habitat, National Petroleum Reserve–Alaska (NPR-A)
These are geospatial data that characterize the distribution of polar bear denning habitat on the National Petroleum Reserve–Alaska (NPR-A). Two datasets are included in this data package, they are both vector geospatial datasets of putative denning habitat (one set each for the western and eastern portion of the NPR-A). Each vector dataset is provided in both ESRI shapefile and Keyhole Markup Language (KML) formats. Denning habitat was estimated from computer interrogation of digital terrain models (DTM) derived from Interferometric Synthetic Aperture Radar (IfSAR) imagery collected by sensors mounted on fix-wing aircraft. Den habitat is defined as abrupt landscape features (e.g., coastal and riverbanks, lake shores) that are likely to accumulate snow to a depth sufficient for polar bears to build a maternal den (i.e., > 1 meter deep).
