Data Used to Compare Photo-Interpreted and IfSAR-Derived Maps of Polar Bear Denning Habitat for the 1002 Area of the Arctic National Wildlife Refuge, Alaska, 2006-2016

Metadata Updated: July 6, 2024

These are geospatial data that characterize the distribution of polar bear denning habitat in the 1002 Area of the Arctic National Wildlife Refuge, Alaska. They were generated to compare the efficacy of two different techniques for identifying areas with suitable den habitat: (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. Two datasets are included in this data package, they are both vector geospatial datasets of putative denning habitat (one dataset each for the manual photo interpretation data and the computer interpreted IfSAR data). Additionally included are: vector data used for sampling and metadata describing the IfSAR-derived digital terrain model (DTM) tiles used to generate the shapefiles. The IfSAR DTM are available for purchase through Intermap Technologies, Inc. All vector data are provided in both ESRI shapefile and Keyhole Markup Language (KML) formats.
