Proof Sheet Old Crow Yukon Terrain Maps

A client was conducting a flood analysis for the small village of Old Crow in northern Canada. Old Crow is built on an alluvial fan close by the banks of the Porcupine River and is vulnerable to flooding. These images combine available CDED DEM data with overlay images prepared from bands 1, 2 and 3 from free GeoBase SPOT data. The images were processed with PANCROMA™ to produce pseudo true color images and then pan sharpened. These is the second set of proof images that were used to develop the final study.
