Imagery data for the Vegetation Mapping Inventory Project of Cumberland Island National Seashore

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 total of 43 map classes were developed to map the vegetation and general land cover of Cumberland Island National Seashore and surroundings, including the following: 32 map classes representing natural/semi-natural vegetation at the association level in the National Vegetation Classification System (NVCS), 1 map class representing cultural vegetation (e.g., developed) in the NVCS, and 10 map classes representing non-vegetated units (e.g., open water bodies, buildings, roads). Features were interpreted using 1:12,000 scale digital color-infrared aerial photography (flown 01 May 2011) through heads-up-digitizing in ArcGIS (Version 10.0, © 2010 Environmental Systems Research Institute, Redlands, California). Polygons were mapped to a 0.5-hectare minimum mapping unit (MMU).
