  • Complementary to the existing small-sized county-level mosaics
  • Natural color (RGB), color infrared (CIR), or NDVI color mosaics available
  • ...

 2. Global Satellite Imagery - Earth Land Surface 2000 Ver. 3 from 2016 update

  • 14.25/15/30/60/90m-resolution, natural and/or false-colour
  • Complete six (6) data sets, multiple styles
  • Unique global mosaics at 30m-resolution (image size: 1,296,000 x 648,000 pixels; file size: 2.29 Terabytes in raw binary; format: optimised JPEG2000), ready-to-use and cost-effective

          - Global mosaic Style 1 (ocean area: uniform colour, e.g. black)
          - Global mosaic Style 2 (ocean area: bathymetric shaded relief)
          - Global mosaic Style 3 (land area: 3D texture; ocean area: shaded relief)

Anyone even with little or no geospatial experience is able to use our large-sized, GIS-ready global mosaics; it can be as easy as opening files! We show you how. 

3. Global Elevation Data - Upgraded

  • 90m-resolution near-global SRTM mosaic with gaps filled
