Geospatial Validation and Topographic Map Revision of the Castner Glacier Area
Mapping in the interior of Alaska has always been a challenge due to the vast and remote aspects of the region. One contemporary method that has been used to map certain areas of the state has been the application of optical satellite data such as the Panchromatic Remote Sensing Instrument for Stere...
