July 21, 2014 - Changes to ESPA Processing and Output Options

On July 29, 2014, the EROS Science Processing Architecture (ESPA) will be upgrading its interface to incorporate more high-level processing options for Landsat 4/5 TM and Landsat 7 ETM+ products.

The interface updates are listed below:

  • Spectral indices derived from surface reflectance, which include:
    • Normalized Difference Vegetation Index (NDVI)
    • Normalized Difference Moisture Index (NDMI)
    • Normalized Burn Ratio (NBR)
    • Normalized Burn Ratio 2 (NBR2)
    • Soil Adjusted Vegetation Index (SAVI)
    • Modified Soil Adjusted Vegetation Index (MSAVI)
    • Enhanced Vegetation Index (EVI)
  • Re-projection options for Polar Stereographic.
  • Re-projection and subset functionality for L1T products.
  • User-defined output formats for GeoTIFF (.tif), HDF-EOS2 (.hdf) and ENVI Binary (.img).
    Please Note: Surface Reflectance data products requested from EarthExplorer will be delivered in GeoTIFF format only.
