Imagery data for the Vegetation Mapping Inventory Project of George Washington Carver 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.

The mapping component was produced by identifying land cover in a three-step process: (1) image objects were generated at 1 m resolution using e-Cognition applied to stacked leaf-on and leaf-off air photos, (2) image objects were coded with land cover classes on-screen, and (3) image objects were cut and corrected via heads-up digitizing at a display scale of not more than 1:1,000 against a back-drop of air photos. Imagery was the most recent available from the National Agriculture Imagery Program. This included 2009 leaf-on true color and 4-band Color infrared (CIR) 1 m resolution photos, and 2007-2009 leaf-off true color 2 foot resolution photos. All images were stacked before image objects were generated.
