Byrd Glacier Historical Air Photo DEM 10m v1
This dataset is comprised of two DEMs (10 m spatial resolution) that were generated from aerial images collected in December 1978 and January 1979 over Byrd Glacier, East Antarctica. The air photos were initially manually processed in 1980 (Brecher, 1982) and then mislaid for 36 years until eventual...
