Interesting! Would your primary goal be detecting new or possible archaeological sites, change detection of known sites, or something else? Any particular areas in mind?
On the anthropology side, it might also be useful for looking at statistical information about populations/settlements that's difficult to collect other ways due to either the remoteness of the area and the frequency of other data sources. Things like nomadic migration patterns or land use in areas like Siberia / Mongolia, Myanmar, or northern Canada.
