geoprocessing - Is there a way to automate the preprocessing of LANDSAT data?

I'm currently enrolled in a remotesensing course, using LANDSAT data.
Part of my course is about standardizing the scenes based on radiance values. I assume that because this is such a tedious task, someone has already figured out a way to automate it.

Are there any tools, ESRI or otherwise that will standardize LANDSAT scenes?

Answer

With GRASS GIS (http://grass.osgeo.org) you can do these steps:

• Import Landsat imagery in a GRASS database using:
  
  
  


• i.landsat.rgb (or i.colors.enhance in GRASS 7) - auto-enhance colors


• i.landsat.toar (addon for GRASS 6, included in GRASS 7) - convert DN to top of atmosphere radiance


• i.atcorr - correct top of atmosphere to surface reflectance


• i.landsat.acca (addon) - cloud identification


• i.landsat.dehaze (addon) - haze removal


• i.landsat.trim trims the "fringe" from the borders of Landsat images
