Durning, L.E., Sankey, J.B., Bedford, A., and Sankey, T.T., 2018, Riparian species vegetation classification data for the Colorado River within Grand Canyon derived from 2013 airborne imagery: U.S. Geological Survey data release,


These data are a species-level classification map of riparian vegetation in the Colorado River riparian corridor in Grand Canyon, Arizona, USA. The classification is derived from 0.2 m pixel resolution multispectral aerial imagery acquired in May 2013. The classification spans the riparian zone of the river corridor between Glen Canyon Dam near Page, Arizona, and Lake Mead at Pearce Ferry, Arizona. The classification is divided into 5 distinct reaches of the river: Glen Canyon, Marble Canyon, Eastern Grand Canyon, Western Grand Canyon upstream of Diamond Creek, and Western Grand Canyon downstream of Diamond Creek. The method used for classification was a combination of supervised Classification And Regression Tree (CART) analysis and [...]

These data are intended to be used as a tool to quantify vegetation species quantity and composition within the riparian corridor of the Colorado River in Glen, Marble and Grand Canyons, Arizona. These data are intended to be applied and interpreted at the spatial scales of: patches of multiple individual plants of the same or differing species; river reach; or the entire riparian corridor (system-wide). The data are not intended to be used at the spatial scale of individual plants. The training and validation tabular dataset are registered and designed to be used with the May 2013 multispectral high resolution image mosaic data (
