Comprehensive geomorphological map of the glacial and periglacial features of East Falklands

Geomorphological mapping was achieved by onscreen digitising directly into Google Earth using the high resolution of imagery available. Six different landforms were recognised based on comparisons with modern periglacial environments. Features which were mapped according to specified criteria and forms include: Stone Runs; Stone Stripes; Stone Pendants; Stone Terraces; Scree and Bedrock outcrops. Mapping criteria were based on morphology and location within the landscape. Landforms were mapped by digitising polygons around the outline of these features, which were determined by the presence of quartzite boulders.

Lineage	Geomorphological mapping was achieved by onscreen digitising directly into Google Earth using the high resolution of imagery available. Landforms were mapped by digitising polygons around the outline of these features, which were determined by the presence of quartzite boulders. Features were mapped as kml file polygons and then transferred into ArcMap, overlying a mosaicked GDEM image of the Falklands. The .kml polygon files were then converted into .shp files. Locations that were accessible and showed interesting landform relationships were ground-truthed in the field.
