Automatic Dem Generation for Antarctic Terrain
Automatic digital elevation model (DEM) generation has become an established technique within mapping agencies. This paper assesses the effectiveness of automatic DEM generation using area‐based matching for glaciated terrain in Antarctica. DEM accuracy is assessed by comparison with check data acqu...
