I have an old article (2007) speaking about GRASS GIS and archaeology:
Conference Paper GRASS, un potente GIS per archeologi
Among the study cases there was one regarding spatio-temporal analysis of satellite images. Unfortunately the article is in Italian. I hope it can be useful anyway. Have a nice day!
Perhaps this is relevant, since we used GIS, satellite imagery and other techniques as part of the process in the rediscovery of a site and the discovery of a new neolithic site in Malta.
