Dataset Abstract:

This data set contains a subset of the SRTM 90-meter data to be used in the CPC Ecuador Projects. The information in this metadata document is primarily the original NASA JPL metadata, as the original data have not been modified. The Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavor, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavor in 1994. SRTM was assigned to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory (JPL), Pasadena, CA, for NASA's Earth Science Enterprise, Washington, D.C.

Quality Assessment (Data Quality Attribute Accuracy Report):

Quality Assessment:

Accuracy report produced by Rodriguez et al. (2005) available at http://www2.jpl.nasa.gov/srtm/SRTM_paper.pdf

Process Description:

Data Acquisition Materials and Methods:

Source or Platform Collection Environment: Space shuttle Endeavor



Source or Platform Program Management: NASA (http://www2.jpl.nasa.gov/srtm/index.html)and USGS EROS Data Center (http://srtm.usgs.gov/)



Source or Platform Mission Objectives: To use C-band and X-band interferometric synthetic aperture radars (IFSARs) to acquire topographic data over 80% of Earth\'s land mass (between 60degN and 56degS) during an 11-day Shuttle mission. Produce digital topographic map products which meet Interferometric Terrain Height Data (ITHD)-2 specifications (30 m x 30 m spatial sampling with <=16 m absolute vertical height accuracy,

<= 10 m relative vertical height accuracy and <=20 m absolute horizontal

circular accuracy). All accuracies are quoted at the 90% level, consistent with

National Map Accuracy Standards.



Sensor or Instrument Descriptions: http://www2.jpl.nasa.gov/srtm/instr.htm



Key Variables: Elevation



Data acquisition methods: All tiles were acquired from USGS.
