Differentiating Barren and Built up areas.

02 April 2013 1 1K Report

How can we effectively differentiate and classify between a barren and a built up area from a satellite image( say LANDSAT TM).

Lakshmi N. Kantakumar

This is quite difficult, if your study area belong to dry region. I would suggest to use Knowledge based approach, you need to derive the rules by examining the spectral information data.

If you have high resolution image use object orient classification in IDRISI. Builtup has rough texture while barren land has smooth texture.
