Top Ranked Topographic Change Polygon and Largest Cut Area

Top ranked topographic change polygon (outlined in yellow): largest cut area (8.75 km2) and largest cut volume (1.25 x 10⁹ m3). This feature is the Bingham Canyon copper mine in north central Utah. From left to right, the images are NED shaded relief, SRTM shaded relief with change polygons overlaid (blue = cut; red = fill), and Landsat image. The dates of the source data for the NED and SRTM are shown. This area is about 5.5 km east-west by 9.7 km north-south.
