Aerial Photography Layers for Utah
HRO | (natural color (RGB) and/or false color (CIR), ~1 ft pixels)
High Resolutaion Orthophotography is color aerial photography typically collected every 2 or 3 years in the spring or fall for select areas in Utah. The resolution is 1 foot or better with a horizontal positional accuracy of +- 75cm for 2006 and 2009 and +- 37.5cm for 2012 imagery. The 2003 Urban Area Orthoimagery (UAO) is considered part of the HRO collection. Currently there is HRO imagery from 2003, 2006, 2009 and 2012.
NAIP | (natural color (RGB) and/or false color (CIR), ~1 meter pixels)
National Agricultural Imagery Program is color aerial photography typically collected ever 2 or 3 years in the middle of the summer. Starting in 2006 the acquisitions have been statewide. The resolution is usually 1 meter with a horizontal positional accuracy of 5 meters. In addition to the 3-band Red Green Blue (RGB) color imagery, there is a color-infrared dataset from 2006, and a 3-band and 4-band dataset from 2009. The 2011 dataset is 4-band for the TIFF images and 3-band for the county moasics. Currently there is NAIP imagery from 2003, 2004, 2006, 2009, and 2011.
DOQ | (black & white, ~1 meter pixels)
Digital Orthophoto Quads are typically Black and White aerial photos with a 1 meter resolution. In some cases the DOQs are .5 meter, color or 4-band. The boundaries of the imagery tiles correspond to the boundaries of 1:24,000 USGS topographic maps. The 1990′s collection is statewide.
