Riparian vegetation classification of the Colorado River Corridor, Grand Canyon, Arizona, 2021—Data

These data are a map of total riparian vegetation (Total vegetation are map units showing the presence of photosynthetically active plants at time of image acquisition) in the riparian corridor of Colorado River in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona, published in a shapefile format. The map was derived from image classification of 0.2-m resolution, multispectral imagery aquired in May 2021 (Sankey and others, 2024). These map 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.These data represent green, photosynthetically active vegetation during the acquisition of the aerial imagery, and do not necessarily represent senesced or defoliated/dead standing vegetation.
