Abstract Imagery and LiDAR data acquisition by a contract with Woolpert, is in response to the flood of 2011. This task consists of color digital aerial imagery acquisition and color digital orthophoto production at 1.0 foot ground sample distance (GSD) over approximately twelve hundred twenty (1220) square-miles along the Yellowstone River and Lidar acquisition over approximately four hundred forty-two square miles along the Yellowstone River. The general purpose of the imagery collection and processing is twofold: to provide data for others to visually denote and quantify inundation damage areas from no damage areas and to provide data for others to visually denote and quantify degree of damage as heavy, moderate and light and for future H and H analysis. The 10,000 foot x 10,000 foot digital orthophoto tiles and the 5,000 x 5,000 foot LiDAR tiles were based on the U.S. National Grid. The final product consists of color digital orthophoto tiles at a 1.0 foot pixel in TIFF format with ASCII TFW file with LiDAR data set.
Purpose The orthophotos and surface data will be used to support Yellowstone corridor studies
