National Park Service Unpublished material Maps Data Contact the Vegetation Characterization Program or Canyon De Chelly National Monument. The dataset consists of mosaiced aerial photography for the Canyon de Chelly National Monument, Arizona. The aerial photographs were photo-interpreted to produce a vegetation cover map of the Canyon de Chelly National Monument. This mosaic of orthorectified photography will be used for reference in a GIS. 20040624 20040207 20040209 Date of aerial photography Complete None planned Canyon de Chelly National Monument, Apache County, Arizona -109.580855 -109.108380 36.319117 35.965298 None Aerial photography mosaic National Park Service NPS None Canyon de Chelly National Monument Apache County Arizona AZ None None Southern Colorado Plateau Network, National Park Service Unknown Network Coordinator mailing

None Entire Extent of the Canyon de Chelly National Monument, Arizona, as well as all areas within a 1 mile buffer were covered by the extent of the final mosaic. Individual aerial photos were previously orthorectified using standard documented procedures and are considered to be accurate. The USDA Farm Service Agency, Aerial Photography Field Office, contracted with FotoFlight Geomatics, Inc. to fly the aerial photography. Scale of photography was 1:12,000, Camera Type: WILD RC10, Camera # 3539, Lens Type: AVIOGON II, Lens # 3036 20040207 Charlie Clement USDA Farm Service Agency, Aerial Photography Field Office Aerial Imagery Specialist mailing and physical address

Scanned photos were orthorectified using Orthomapper software with existing 10-m DEM and 1-m DOQQ files for registration. Root mean square (RMS) error was targeted at 2.0 m or less in each direction with a maximum error of 4.0 m for any single registration point. Where possible 12 points were used for rectification to allow for a second order transformation. 2006 Hanna Moyer U.S. Geological Survey Leader - GIS and Remote Sensing Team mailing and physical address

Each aerial photo image was displayed and an area of interest was digitized to exclude the border and fiducials. The mosaic tool was used to mosaic the aerial photos together by flightline: 2103 (west), 2703 (middle), and 3003 (east). Each flightline was mosaicked independently using approximately alternating aerial photos. For each flightline the best mosaic resulted from the following options: 1) color correction - no color correction, 2) overlap function - overlapping aerial photos, and 3) output option union of all inputs and clipping to the 1-mile buffered boundary for the national monument. The three flightline mosaics were then mosaicked using the following options: 1) color correction histogram matching with the matching method being overlap areas and histogram type being band by band, 2) overlap function overlay, and 3) output option union of all inputs. 20100927 Bob Waltermire U.S. Geological Survey Leader - GIS and Remote Sensing Team mailing and physical address
