We create 3D building models on the Google base map using the applications Terra Photo, Terra Scan. and Terra Model. Then it is followed by texturing of the buildings for better visualization. Texturing is mainly done with the help of the client-supplied inputs i.e. images of the buildings taken from various angles. Texturing the sidewalls of the buildings are usually done by the oblique images and for True orthophotos are often used for the ground and the top of the objects. True orthophotos are specially generated orthophotos where no sidewall of buildings can be seen from the top, which is necessary for realistic visualization of the ground.

Different Level-of-Details of 3D City Models can be semi-automatically generated using airborne imagery and laser scanner data. A combination of different texturing procedures improves the realistic recognition of virtual city models. After completion of the texturing process, the final data is delivered to the client in the required format.
