Shuttle Radar Topography Mission (SRTM) 90m Digital Elevation Database v4.1 for French Guiana

Dataset downloadable for free on the website of the Consultative Group on International Agricultural Research - Consortium for Spatial Information (CGIAR-CSI). The SRTM digital elevation data provided on this site has been processed to fill data voids, and to facilitate it’s ease of use by a wide group of potential users. Digital elevation models (DEM) for the entire globe, covering all of the countries of the world, are available for download on this site. The SRTM 90m DEM’s have a resolution of 90m at the equator, and are provided in mosaiced 5 deg x 5 deg tiles for easy download and use. All are produced from a seamless dataset to allow easy mosaicing. These are available in both ArcInfo ASCII and GeoTiff format to facilitate their ease of use in a variety of image processing and GIS applications. Data can be downloaded using a browser or accessed directly from the ftp site.

Statement: The data distributed here are in ARC GRID, ARC ASCII and Geotiff 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 using interpolation methods described by Reuter et al. (2007). Version 4.1 has the following enhancements over V4.0: - Improved ocean mask used, which includes some small islands previously being lost in the cut data. - Single no-data line of pixels along meridians fixed. - All GeoTiffs with 6000 x 6000 pixels. - For ASCII format files the projection definition is included in .prj files. - For GeoTiff format files the projection definition is in the .tfw (ESRI TIFF World) and a .hdr file that reports PROJ.4 equivelent projection definitions.
