Batch processing atmospheric correction using ARCSI

spectraldifferences

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…

About WQ

I received my PhD (2013) in Remote Sensing, Earth and Space Science at the Dept. of Aerospace Engineering Sciences, University of Colorado, Boulder, USA, under a Fulbright fellowship. Currently, I'm an Assistant Professor in the Dept. of Space Science at Institute of Space Technology (IST), Islamabad, Pakistan, where I have been a founding member of the Geospatial Research & Education Lab (GREL). My general expertise is in Remote Sensing where I have worked with various remote sensing datasets through my career, while for my PhD thesis I specifically worked on Remote Sensing using SAR (Synthetic Aperture Radar) and Oceanography, working extensively on development of techniques to measure ocean surface currents from space-borne SAR intensity images and interferometric data. My research interests are: Remote sensing, Synthetic Aperture Radar (SAR) imagery and interferometric data processing & analysis, Visible/Infrared/High-resolution satellite image processing & analysis, Oceanography, Earth system study and modelling, LIDAR data processing and analysis, Scientific programming. I am a reviewer for IEEE Transactions on Geoscience & Remote Sensing, Forest Ecosystems, GIScience & Remote Sensing, Journal of African Earth Sciences, and Italian Journal of Agronomy. I am an alumnus of Pakistan National Physics Talent Contest (NPTC), an alumnus of the Lindau Nobel Laureate Meetings, a Fulbright alumnus, and the Pakistan National Point of Contact for Space Generation Advisory Council (SGAC). I was an invited speaker at the TEDxIslamabad event held in Nov., 2014. I've served as mentor in the NASA International Space App Challenge Islamabad events in April 2015 and April 2016.
