High-resolution (0.20 m) digital images collected during an aerial LiDAR survey of the Lower Rio Puerco during April and July 2005. Details on data collection and processing methods are provided in an unpublished report by Spectrum Mapping, LLC (August 2005; see Supplemental Information). The images are Spectral Imagery LiDAR Composite (SILC) in which individual image pixels have been associated with individual xyz values to improve feature discrimination, including bare earth surfaces, as well as quality control processing. Stated horizontal and vertical accuracies are <0.30 m rms error in x, y, and z. This image set has been modified from the original by clipping large areas of no data (white space) from the outer...
An aerial LiDAR survey of the lower Rio Puerco was conducted in April and July 2005 by Spectrum Mapping, LLC, under contract with the USGS (Contract #14040050). The surveyed reach extends from the NM Highway 6 crossing 55 km downvalley to the old Highway 85 bridge near the USGS streamgage near Bernardo, NM. Survey procedures, equipment and products are described in the Rio Puerco Project Report (Spectrum Mapping, LLC, Aug. 1, 2005), provided with this data set. The survey data include breaklines (shapefiles) used to process the elevation data, bare-earth Digital Terrain Models (DTMs) with 2-m cell size in the ArcGrid format, LAS-formatted files, and the original random xyz data. Results from analyses using these...
