High-Resolution Orthorectified Imagery from 2008, Niwot Ridge LTER Project Area, Colorado

This image tile is part of an orthophotography project covering contiguous areas of interest in and adjacent to the jurisdictional boundary of the Denver Region Council of Governments (DRCOG) in central Colorado. The project is known as the Denver Region Aerial Photography Project (DRAPP) begun and completed in 2008. The tiles are images which depict color digital aerial photographs acquired in the spring of 2008 during leaf-off conditions and in early summer of 2008 over mountainous areas to minimize snow cover. Lens and terrain distortion have been removed and tonal differences between adjacent images have been minimized to form a mosaic of the entire project area. The project area includes The Denver Metropolitan area and both eastern plains and western mountains adjacent to the metro area. Orthorectified imagery is assumed to depict features at ground level, so above ground features may show some distortion from elevation. The only exceptions to this are bridges and elevated roads, which have been checked for distortion and manually replaced by their previous unrectified versions. Each orthorectified pixel is exactly one half foot square in the metro area and one foot square in the plains and mountain areas. Quality and accuracy of this orthophotography was evaluated independently. The image products conform to American Society for Photogrammetry and Remote Sensing (ASPRS) Class I Standards for 1"=200' horizontal mapping.
