The idea - to map TLV in 3D using any means possible.
We maintain the data on official TAMI superclusters and release it as emperors of the digital realm.

metroscape has 3d models of a few tens of bldgs in tlv
- requires windows/mac for the plugin, and no download link for any model (STL/other). -- Alon
googleearth has also a few tens of tlv buildings
will google come and nail it all down ? if we scoop them we get to ride in the google helicopter.
The 3d scanners such as mantis and kinect are apparently not set up for long ranges like 10-50m which is what we're after to get buildings. Satellite photos probably are not of help here due to shallow angles and probable closed source-ness. A quadcopter may be of use but would take massive time and batteries. Rough order of magnitude of the problem:
one street every 50m
about 20km^2 of area in TLV
--> 800 km of street in TLV
--> a car / bike mounted 3d scanner is needed.
from several cameras with known relative angles and baseline, reconstruct 3d info using known algorithms
try to obtain 3d info from a large-ified kinect hack
it is possible to build a massive structured light rig, using a 3000+ ansi projector and a DSLR.
