Summary
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 (<4 m diameter [...]

Registration points were typically center of mass of small (<4 m diameter canopy) shrubs. Geomorphic parameters derived from mapping from these images were presented in the following publications:

Purpose
The registered and rectified 1996 NAPP photo segments were used to map features including the channel and arroyo centerlines, estimated tops of channel banks, tops of the arroyo walls, and bottoms of the arroyo walls. Mapped 1996 features were compared to features in other years to determine geomorphic change through time. Selected images also were used to determine percent of shrub canopy cover on the arroyo bottom.
