Upcoming Changes to USGS ESPA Processing and Output options of Surface Reflectance Climate Data

usgs_2
Today I received an email from USGS  as a notice of changes coming soon to the USGS EROS Science Processing Architecture (ESPA) interface (https://espa.cr.usgs.gov/) , that allows you to process Landsat 4/5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) data to Surface Reflectance.

On July 29, 2014, the ESPA interface will be upgraded to incorporate more high-level processing options for Landsat 4/5 TM and Landsat 7 ETM+ products. 

Updates Include: 

  • Spectral indices derived from surface reflectance..
  • 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).
  • 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)

Samples of these can be downloaded from http://espa.cr.usgs.gov/validations/espa_output_formats/.

(Note: Surface Reflectance data requested using EarthExplorer will be delivered in GeoTIFF format only.)
