Apart from NDBI, could you name a few indices for urban expansion? I have done some search on google but haven't found anything that could help me. Perhaps,
What I'm interested is also: road/infrastructure, parks, parking lots, commercial areas development in the urban environment.
I need to analyze some orthophotos of a city and to do that I need to apply some indices to my analysis. As for software, I'm going to have at my disposal: ERDAS, ArcGIS, Open Source.
