Satellite classification

Discussion created by Palebot on Jan 30, 2014
I'm a tad rusty on classifying satellite imagery. I am interested in classifying (1) Geoeye-1 data and (2) Landsat 8 data. Essentially I am working in an area with explosive development. I would like a relatively easy classification that can better distinguish housing and buildings from agricultural land, forest, and water. Does anyone have any suggestions? My next step would be to convert the classified raster images to polygons of different land-use types in order to associate them with point data I have of archaeological sites. A NDVI does not seem the way to go in general.
