Previous posts have covered atmospheric correction using the Atmospheric and Radiometric Correction of Satellite Imagery (ARCSI) software. When a large number of scenes require processing then commands to automate steps are desirable and greatly simplify the process.
ARCSI provides a number of commands which are useful for batch processing:
- arcsisortlandsat.py sorts the landsat ‘tar.gz’ files into individual directories for each sensor (i.e., LS 5 TM) and also builds a standard directory structure for processing.
- arcsiextractdata.py extracts the contents of verb|tar| and verb|tar.gz| archives with each archive being extracted into an individual directory.
- arcsibuildcmdslist.py builds the ‘arcsi.py’ commands for each scene creating a shell script.
The files used for this tutorial are shown below, but others could be downloaded from from earthexplorer and used instead.
Sort Landsat Scenes
The first command to execute is ‘arcsisortlandsat.py’ which needs to be executed from within the directory containing files:
This will generate the following…
