      <abstract>SRTM 90 m elevation data for the department  of  Risaralda, Colombia

PROCESSED SRTM DATA

The data distributed here are in ARC GRID format, in decimal degrees and datum WGS84.  They are derived from the USGS/NASA SRTM data.  CIAT have processed this data to provide seamless continuous topography surfaces.  Areas with regions of no data in the original SRTM data have been filled in using interpolation methods.  A full technical report on this method is in preparation.</abstract>

      <purpose>With the release of the new National Aeronautics and Space Administration (NASA) topography data from the Shuttle Radar Topography Mission (SRTM) a new era of spatial analysis is upon us. Topography is a fundamental factor in defining water availability, local climate, soil type, and light receipt, and is therefore a key factor in any agricultural or environmental spatial research. The Land Use Project has just finished processing the data for Asia, Latin America, the Pacific Islands, Europe, and North America, and is offering these data upon request for institutions or projects involved in international development. We have also made some preliminary analyses of data quality within the context of the tropics, showing that the SRTM data are potentially of great value to globalizing site-specific research. Further information is available in our SRTM 90 m elevation data Web page.</purpose>
      <supplinf>The SRTM data will cover the entire globe with a 3 arc second (approx. 90m) digital elevation model. A 1 arc second data product also exists, but is not available on general release. The data is currently available for small regions for download from the National Map Seamless Data Distribution System, or is available for the entire globe from an ftp site. The vertical error is said to be less than 16m.

The data currently being distributed by NASA contains no data holes where water or heavy shadow prevented the quantification of elevation. These are generally small holes, which nevertheless render the data less useful, especially in fields of hydrological modeling.

The data currently being distributed by NASA contains no data holes where water or heavy shadow prevented the quantification of elevation. These are generally small holes, which nevertheless render the data less useful, especially in fields of hydrological modeling.

The Land Use project, in collaboration with Robert Hijmans (University of California, Berkeley) and Andy Nelson (University of Leeds), have imported the SRTM data, and performed some processing to fill in these no data. This process involved the production of contours, and the re-interpolation of these derived contours back into a DEM. We then used the interpolated DEM values to fill in the original no data holes from the crude SRTM data. This was done using Arc/Info and an AML script which is available for download. Questions regarding the use of this AML should be directed to Andy Jarvis.</supplinf>
