资源简介：
These are polygons that contain vegetated pixels in the May, 2002 imagery from aerial overflight of the Grand Canyon. Vegetation was mapped between stage elevations of approximately 8,000 and 250,000 cubic feet per second. Please refer to Ralston et al., 2008 for detailed methods of the classification of vegetation from the aerial imagery. The total vegetation dataset from Ralston et al., 2008 was further edited by J. B. Sankey to only include polygons of vegetation with area greater than 1 square meter.
