Imagery data for the Vegetation Mapping Inventory Project of Hopewell Furnace National Historic Site

Metadata Updated: November 12, 2020

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.

Aerial photographs were obtained by Kucera International, flown in April 2002, at a scale of 1:6000. The delineation of mapping polygons using onscreen digitizing is greatly facilitated by the availability of a single seamless digital image of the target area (i.e. extent of park). This is accomplished by scanning hard copies of aerial photography to create digital images and then geo-referencing and ortho-correcting each scanned image. These individual images are then digitally joined to create a single seamless digital aerial photo mosaic. The positional accuracy of the photo mosaic is then assessed by obtaining actual field coordinates for distinct landmarks in the digital image using global positioning system equipment. Field and digital image coordinates are then compared to assess the spatial accuracy of the digital image.
