[HOT] UAVs

[Andrew Buck]

It is not the rendering and serving of the tiles that is the problem with
the imagery processing, it is the orthorectification that is tricky.

UAV's are required to fly quite low which means that the individual frames
are quite small, requiring tens or hundreds to cover even a small town.  At
this scale it is not possible to manually orthorectify these images and
more sophisticated techniques need to be applied.  This is the part of the
solution that Robert was referring to.
