Imagery data for the Vegetation Mapping Inventory Project of Grand Portage 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.
A set of CIR aerial photographs was collected on October 4, 2006. This photo mission was funded by the NPS VIP, and supervised by GLKN staff. This set of photography covered the entire GRPO vegetation mapping project extent at 1:12,000-scale and was the primary imagery used in photointerpretative mapping.
In support of mapping from the CIR photos, we used a set of TC aerial photographs (1:8,000-scale) that was collected May 2, 2003, providing deciduous leaf-off viewing of the entire extent. This photo mission was funded by GRPO and supervised by GLKN staff. Having the TC photos gave interpreters a definite advantage in determining evergreen tree and shrub components within forest communities otherwise obscured by deciduous tree canopy on the fall-season CIR photos, thus giving credence to Avery’s statement regarding lack of a single all-purpose film emulsion.
To assure stereo viewing and full aerial coverage, aerial photo missions were planned with a 60% forward-lap and 30% side-lap. Contact prints of both CIR and TC photo sets were produced for fieldwork use by mappers and vegetation crews. Diapositives of the CIR photo set were produced for photointerpretative mapping.
