Imagery data for the Vegetation Mapping Inventory Project of Black Canyon of the Gunnison National Park
Description
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.
The mapping component of the BLCA project used a combination of methods to interpret and delineate vegetation polygons. Initial line work was prepared by USBOR photointerpreters who delineated the most contrasting signatures, e.g., water bodies, exposed shoreline, unvegetated geology, land use types, and vegetation at the physiognomic level. The project photo interpreter used this baseline mapping and refined it by examining digital orthophotos in stereo. The stereo photography was used as needed to distinguish fine scale vegetation patterns. Ancillary datasets such as plot and observation point data and classification and local descriptions of plant associations were used by the photointerpreter to assist with map class definitions and manual delineations.
