Vegetation and water classifications for a segment of the Paria River upstream of the Colorado River Confluence, Arizona, USA
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 gNDVI <= 0.2. Each classification dataset contains unclassified pixels (0) and vegetation or surface water pixels (1) and are published as Cloud Optimized GeoTIFF raster datasets.
