" photogrammetry has been around for a few years now,but it is very limited. it might be a good starting point for a model..but expect to tweak the mesh & texture in external programs to get anything worth using. it's good when used for distant buildings that only take up a few pixels on screen,but once you zoom into the model blind spots & other erors become obvious" erm... watch that Dr Who episode.. they were only a coupla hundred feet up over London during an airraid.. and non of the limits you've said were evident...
