Why bother with Infrared ?
Better atmospheric penetrationMuch better land/water contrastMuch better vegetation differentiationReveals unique differences between different kinds of surfaces

3D Perspective View Created to Illustrate Proposed Road
The elevation Model has been reprojected, looking North
The satellite image has been draped over the upper surface
This could be imagined as one frame of a video fly-thru !

Existing roads in yellow
Proposed road in red
Overall portrayal of the project region is understandable to the public
