Archaeological remote sensing with GRASS imagery modules

PerryGeo has an interesting post on his blog about using the GRASS i.* modules to find impervious surfaces. I have no experience in archaeological remote sensing (even tough here at my department there’s a great lab), but this tutorial should be useful for those who have large survey regions to cover and want to find possible settlement sites, given that even a small village needs a few “usable” acres.

If you have good resolution aerial images of your study region, you might want to try this.
