Images for Structural Mapping

Overview
This global regional elevation data set provides unprecedented coverage and detail for regional scale mapping. Ten metre contours, fifty metre gridded raster elevation and a fifty metre colour image with shadows and highlights provide detail on elevation and lineaments.

• The first highly accurate digital elevation model covering most of the World.
• In many areas, this dataset is better than any existing public domain DEM available.
