This dataset consists of digital scans of color infrared aerial photography from the Upper Mississippi River collected in 1975.

The 1970s images were obtained as digital scans on CDs, with no metadata. Source information for the original aerial photographs is not available. Original photo scale was about 1:40,000 for the 1975 images (filenames beginning "r75")and 1:12,000 for the 1979 images (filenames beginning "rfl"). I registered and rectified these images using identifiable common points from 1996 DOQQs. See the description of positional accuracy below. Data derived from features mapped from the 1970s images were presented in: Friedman, J.M., Vincent, K.R., Griffin, E.R., Scott, M.L., Shafroth, P.B., and Auble, G.T., 2015, Processes of arroyo filling in northern New Mexico, USA, GSA Bulletin, 127(3/4), 621-640. doi: 10.1130/B31046.1

1996 georeferenced aerial photographs cover the lower Rio Puerco from the confluence with the Rio San Jose 70 km down-valley to the confluence with the Rio Grande. The images were obtained from enlargements of 1:40,000 scale National Aerial Photography Program (NAPP) photographs printed from negatives at a scale of 1:5,000, then scanned at 600 dpi. Pixel size of the raster images is about 0.22 m, compared to the DOQQs, which have 1-m pixel size. The segments were registered and rectified in ArcINFO using common points from USGS DOQQs published in 1999, which were derived from the same 1996 NAPP photo set, with terrain corrections from a 1-degree DEM applied. Registration points were typically center of mass of small...

Geomorphic features mapped from historical aerial photographs (1935, 1950s, 1970s, and 1996), satellite imagery (November 2006), and digital aerial imagery (Standard Imagery LiDAR Composite; Spectrum Mapping, LLC, 2005) are provided in shapefiles for each year of data. Features mapped are tops of the arroyo walls, edges of the arroyo bottom (covering the active floodplain and channel), tops of channel banks, the channel centerline, canopy cover, and 2006 flood sand deposits. In addition, shapefiles containing a reference arroyo centerline, points at 0.5-km intervals along the arroyo centerline, and polygons identifying the 0.5-km arroyo segments are provided. Individual metadata files describe the contents of each...

The 1950s images were downloaded from Earth Explorer as medium-resolution scans of aerial photographs, with pixel size ranging from 1.33 to 2.32 m. Original photo scales were 1:54,000 or 1:20,000. (See Source Citation below.) I registered and rectified these images using identifiable common points from 1996 DOQQs. Images with filenames beginning "r37" were acquired 11-29-1953. Images with filenames beginning "r43" were acquired 01-31-1954. Image r1954r49_6786.tif was acquired 02-03-1954. Remaining images have the date of acquisition in the filename, starting with the format "ryymmdd...".
