INTRODUCTION

 

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.

This data cannot be downloaded.

METHODS

 

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.
