These data include image-based classifications of total vegetation from 1965, 1973, 1984, 1992, 2002, 2004, 2005, and 2009, and characteristics of the river channel along the riparian area of the Colorado River between Glen Canyon Dam and Lake Mead Reservoir.

These data are classified maps of water in the Colorado River at a discharge of approximately 227 meters squared/second in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona. The data are derived from interpretation of multispectral high resolution airborne imagery that was acquired in May 2013. The water classification data have the same 0.2-meter ground resolution as the imagery. These data have not undergone a statistical accuracy assessment, but they are based on methods that included image interpretation to exhaustively identify water which have been shown to produce very high classification accuracies and excellent correlation between maps of total vegetation produced by independent analysts and...

These data were used for the development and validation of the automated workflow for mechanistic segregation of geomorphic transport mechanisms presented in the manuscript "Geomorphic Process from Topographic Form: Automating the Interpretation of Repeat Survey Data in River Valleys." These data include (1) raster digital surface models from 2002, 2009, and 2013 of seven sites along the Colorado River in Grand Canyon and associated digital elevation models of difference (DoDs), (2) landscape information for each of the seven sites as vector polygons, including the site extent, area of bare sediment, flood inundation extent, and area of vegtation, (3) the locations of 113 field validation points used to assess the...

These data are classification maps of total riparian vegetation along the Colorado River in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona. The data are derived from interpretation of multispectral high resolution airborne imagery that was acquired in May 2013. The total vegetation data have the same 0.2-meter ground resolution as the imagery. These data have not undergone a statistical accuracy assessment, but they are based on methods that included image interpretation to exhaustively identify total vegetation which have been shown to produce very high classification accuracies and excellent correlation between maps of total vegetation produced by independent analysts and ground truth. The data represent...
