I’ve not done this before but I think this is an interesting PhD topic for someone and of course there is a 3D city angle!
University College London and the Ordnance Survey are currently inviting applications for a 3-year PhD studentship in “Creating Dynamic3D City Models for Smarter Cities” which will examine the creation of multiple 3D models from a single data source (through generalisation/abstraction). The PhD will be supervised by Dr Claire Ellul (UCL) and by Jeremy Morley (Ordnance Survey). The closing date is the 28th July.

Anyone interested is welcome to contact Claire Ellul on c.ellul@ucl.ac.uk for an informal chat.
