Thank you all for the helpful replies. This gives me a lot to work with. It seems that acquiring GPS coordinates should not be that difficult to obtain on site, but we would prefer the accuracy to be <20m from were the picture was taken. Even course geo-references would be valuable as well.
I have one more small question to ask: for those of you who have used P&S cameras with built-in GPS units, were you able to view the lat/long in the display view right after you took the picture? Also, is it possible to convert among different geo-coordinate systems (i.e. degrees minutes seconds to decimal degree, etc.) in the settings view of some cameras?
