U.S. Geological Survey, and Denver Regional Council of Governments (DRCOG), 2013, USGS High Resolution Orthoimagery for Denver, Colorado: 13SDE515205_201203_0x3000m_4B_1: U.S. Geological Survey: Sioux Falls, SD,,,


"This metadata describes the 2012 digital orthoimagery covering the 10 county DRCOG project area (Denver Metro (A1), Eastern Plains (A2), Mountains (A3), Weld County (A4)). This 1:1200 scale imagery is comprised of 4-band RGBIR color orthoimagery with a GSD (Ground Sample Distance) of 0.15m (0.5') (A1 and A4) and 0.30m (1.0') (A2 and A3). Imagery was collected with the Leica ADS40 digital sensor and processed with Leica GPro software. Imagery is projected in the Universal Transverse Mercator (UTM) Coordinate System, UTM zone 13 for the northern hemisphere. Horizontal and vertical datums are NAD83 and NAVD88(GEOID09) respectively." An orthoimage is remotely sensed image data in which displacement of features in the image caused by terrain [...]

A digital orthoimage is a geometrically accurate photographic record of landscape conditions at the time of the corresponding aerial photography. As such, High Resolution Orthoimagery is useful for a variety of applications, such as environmental monitoring, facility engineering/maintenance, city/county planning, property line review, etc. The digital orthoimage can be used alone or as a raster basemap for corresponding vector line mapping. The detailed focus of High Resolution Orthoimagery provides emergency responders critical information in determining the best evacuation routes, alternative routes and safe access to aid. High Resolution Orthoimagery assists law enforcement personnel in determining the best locations to place surveillance cameras in high-traffic urban areas and popular attractions. The data assists Federal, State and local emergency responders in planning for homeland security efforts. This data also supports The National Map.
