These are data that characterize the distribution of polar bear denning habitat in 1002 Area of the Arctic National Wildlife Refuge, Alaska. They were generated to compare the efficacy of two different techniques: 1) from a previously published study (Durner et al., 2006) that used manual interpretation of aerial photos and 2) from computer interrogation of interferometric synthetic aperture radar (IfSAR) digital terrain models. Data include vector shapefiles of putative denning habitat derived using both methods, as well as a description of the IfSAR-derived digital terrain model (DTM) tiles used to generate the raster shapefiles. The IfSAR DTM are available for purchase through Intermap Technologies, Inc., and are not provided in the data release.
