Open-File Report 2004–1322
The digital shaded relief map of Venezuela is a composite of 3-arc-second (approximately 90-meter) elevation data, captured during the Shuttle Radar Topography Mission (SRTM) in February 2000. The SRTM, a joint project between the National Geospatial-Intelligence Agency (NGA) and the National Aeronautics and Space Administration (NASA), provides the most comprehensive international digital elevation dataset ever produced. The 11-day flight mission aboard the U.S. Space Shuttle Endeavour obtained elevation data for about 80% of the world's landmass through the use of single-pass Interferometric Synthetic Aperture Radar (InSAR) technology. This publication includes a colorized relief image of Venezuela (GeoTIFF format) and the elevation data (ESRI Grid format) used for rendering the image. These datasets are intended to accompany U.S. Geological Survey Open-File Report 2005–1038 (http://pubs.usgs.gov/of/2005/1038/) and U.S. Geological Survey Data Series 199 (http://pubs.usgs.gov/ds/2006/199/). SRTM data in version 2.0 have been processed using the latest data-void filling algorithms and represent a significant improvement to the data used in version 1.0. |
