Imagery data for the Vegetation Mapping Inventory Project of Chaco Culture National Historical Park
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.
Photo interpretation was done using the the 9×9 in, 1:12,000-scale true color photographs. Mylar overlays placed on each aerial photo allowed us to make notes and delineate polygons. At this stage of interpretation we used a stereoscope to help recognize complex photo signatures and topographic features on the 9×9 in aerial photos. We then manually transferred these to the orthophoto basemap. Finally, in order to insure completeness and accuracy, digital transfer specialists reviewed all of the interpreted orthophotos for consistency and recommended changes where necessary. Once all the obvious vegetation and landuse classes were delineated we proceeded into the second stage. The GPS-located vegetation plots collected by the field crew were instrumental to the photo interpretive effort. These plots gave us a good idea of what the signatures of the individual map units represented.
