RGB and Infrared Stereo Models

The XEOS aerial photos allows stereoscopic vision and mapping.  Their resolution is 5 cm and they offer a high x,y,z accuracy. The stereo models can be used in color RGB and infrared false color to facilitate the interpretation of vegetation.

XEOS Imaging’s program aims to update the stereo models of medium and major Canadian cities every two years.
