Thermal Imagery

Once combined with OS MasterMap or a similar building polygon database it is possible to measure the heat loss from individual buildings and pinpoint the most inefficient properties.
The image file available for download here is a greyscale TIFF image and its accompanying world file.

3D BUILDING MODELS

Building Models - High Level of Detail

3D Studio Models are accurate and detailed 3D building models that have been textured with our aerial photography. These models are designed to drop straight into today's 3D visualisation software such as 3D Studio MAX & Rhinoceros. You'll soon be creating stunning fly thrus and visually dynamic pictures.


The downloadable file include .DGN, .DWG, .DXF and .FBX.

Building Models for Computer Aided Design

3D building models in formats compatible with commercial CAD software such as AutoCAD and MicroStation. The models are drawn to a geographic coordinate system for accurate measurement and planning. Once in your CAD software, you can rotate, navigate and zoom in to and around the buildings.


The downloadable file include .DGN, .DWG, .DXF and .FBX.
