Description :
The results of an experiment to compare glacial geomorphology mapped from remotely sensed imagery with 1 : 10,000-scale field mapping are presented. The field mapping was validated against high resolution LiDAR imagery of an area glacierized during the Younger Dryas and found to provide a representation of the glacial geomorphology. The experiment consists of comparing the field mapping with digital elevation models (Shuttle Radar Topography Mission C-Band, Landmap, OS Panorama, OS Profile, NEXTMap) and satellite imagery (Landsat Thematic Mapper) of a region of central Scotland, north of Glasgow. Attention is given to glacial lineaments, moraine ridges and eskers.
