There seems to be continued interest in outdoor space imaging and I know that Chris has said “no” previously to this but it won’t go away. Adding GPS locating and a mapping convention for items that would be included or would not, trees etc would seem to be the only items missing. Is that all that is necessary or am I missing something? If you only had GPS positioning even if you did not draw anything other than buildings at least the user would know where they were positioned when looking at a pano. So do we just need GPS?
