Summary

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 total vegetation [...]

Purpose

These data are intended to be useful for management, monitoring, and research of riparian vegetation in the Colorado River downstream of Glen Canyon Dam. They represent the most complete and up-to-date census of the area covered by vegetation in the riparian corridor at the time of image acquisition in May 2013 (see Durning and others., 2016 for details of the acquisition). These data can be used in GIS for change detection with other vegetation datasets to assess spatiotemporal dynamics of riparian vegetation associated with river regulation and associated resources in the Colorado River ecosystem such as sandbars, campsites, or archeological sites. These data can also be used to transform the digital surface model (DSM) co-collected with the multispectral imagery into a bare-earth digital elevation model (DEM) through the removal of vegetation canopies and interpolation of the elevation data.
