Topographic aspect of the Falkland Islands derived from SRTM data

The dataset is a raster file describing the aspect of the terrain derived from the SRTM data. Aspect data correspond to the values of the compass direction that a slope faces.

Lineage The SRTM tiles of the Falkland Islands were downloaded from USGS website and mosaiced into a unique file. Aspect was modelledin QGIS based on the findings of Zevenbergen and Thorne (1987), which suggest to be more suited towards relatively smoother landscapes with less pronounced topography. The model output was reclassed into values, based on the cardinal and intercardinal directions (i.e., north, north-east, east facings), rather than degrees. However, original data values (0-360) have been kept and available upon request.
