Summary

These data represent total vegetation and surface water along approximately 12 kilometers of the Paria River upstream from the confluence of the Colorado River at Lees Ferry, Arizona. They are derived from airborne, multispectral imagery obtained in late May 2009, 2013, and 2021, collected with a push-broom sensor with 4 spectral bands depicting Blue, Green, Red and Near-Infrared wavelengths at a spatial resolution of 20 centimeters. The vegetation classification data were created using a supervised classification algorithm provided by Harris Geospatial in ENVI version 5.6.3 (Exelis Visual Information Solutions, Boulder, Colorado). The water data were created using a Green Normalized Difference Vegetation Index (gNDVI) threshold of [...]

Purpose

These classification data represent total vegetation and surface water as depicted in multispectral aerial imagery for a segment of the Paria River from the confluence with the Colorado River upstream for approximately 12 kilometers. These data can be used to detect changes in vegetation or surface water extent, or as a baseline for future research, including species-level vegetation mapping or as a water mask or layer to aid in geomorphological or hydrological research.
