The Shuttle Radar
Topography Mission(SRTM), a joint project of the National
Geospatial-Intelligence Agency (NGA) and the National Aeronautics and Space
Administration (NASA), obtained elevation data on a near-global scale to
generate the most complete high-resolution digital topographic database of the
Earth. SRTM consisted of a specially modified radar system that flew onboard the
Space Shuttle Endeavour during an 11-day mission in February of 2000. Digital
elevation models can be made from these detailed SRTM elevation data. The model
produced for Newfoundland and Labrador allows
identification and mapping of large-scale glacial features, some previously
unidentified, as well as delineation of known features.
cannot be downloaded.
The data for Newfoundland and Labrador
were downloaded, and examined using "Global Mapper" software (http://www/globalmapper.com/). This
product allows various means of visualization, including easy manipulation
of sun angles, application of varying vertical exaggeration and overlaying
of other images. Images produced in Global Maper were imported into ArcGIS for
examination and output.
The elevation model image displayed in the Geoscience
Atlas uses false shaded relief, illuminated from xxxxx at an altitude of xxxx
degrees, and with a vertical exaggeration of xxx.
