Slope Maps

The slopes in two of the three survey zones (western and central) are provided in two GIS formats: Idrisi (Version 14--Kilimanjaro) and GEOTIFF raster files. These are compressed self-extracting files for Windows, and thus must be uncompressed on a computer running the Windows operating system. After downloading, place the files in the desired folder and double click them. Each Idrisi compressed file will produce two files with the same name and the extensions .RST and .RDC. Each GEOTIFF compressed file will produce two files with the same name and the extensions .TIF and .TFW. The cell values in the GIS files are as follows:

  • 0 = Outside the survey area
  • 1 = Less than 10% slope
  • 2 = About 20% slope
  • 3 = About 35% slope
  • 4 = About 50% slope
  • 5 = About 70% slope
  • 6 = Greater than 90% slope

For Idrisi files, click here to download the file WESTERN_SLOPE_IDRISI.EXE (199 Kb) or the file CENTRAL_SLOPE_IDRISI.EXE (39 Kb) and ask your Web browser to save it to a disk. (Return here with your browser's BACK button if necessary.)

For GEOTIFF files, click here to download the file WESTERN_SLOPE_TIFF.EXE (199 Kb) or the file CENTRAL_SLOPE_TIFF.EXE (39 Kb) and ask your Web browser to save it to a disk. (Return here with your browser's BACK button if necessary.)
