Imagery data for the Vegetation Mapping Inventory Project of Devils Tower National Monument
1997. Imagery data for the Vegetation Mapping Inventory Project of Devils Tower National Monument
This reference contains the imagery data used in the completion of the baseline vegetation inventory project for the NPS park unit. Orthophotos, raw imagery, and scanned aerial photos are common files held here. In late May and June of 1997, after a preliminary vegetation map had been prepared by the photointerpreter, a map validation step was performed in which further data were collected to obtain more information on the vegetation types and to better correlate the vegetation with the signatures on the aerial photographs. With the exception of two communities, every polygon within the Monument boundaries that had not been sampled the previous year was visited. This resulted in the collection of thirty-eight observation points.
