The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Collectively, the CAHA spatial database layer is composed of 2,437 polygons covering 11,749 ha, with an average polygon size of 8.5 ha. Map classes representing natural/semi-natural types in the NVCS apply to 1,924 polygons (79.0% of all polygons) covering 7,401.6 ha (63.0 % of entire area) with an average polygon size of 3.6 ha. Of these natural/semi-natural types, the Atlantic Coast Interdune Swale dominates, both in frequency of polygons (488), and in size (2,050 ha). Needlerush High Marsh is also a widespread association with 408 polygons covering 1,279.9 ha. Non-vegetated areas (including developed areas and water) consist of 513 polygons (21.1% of all polygons) and cover 4,347.9 ha (37.0% of the entire area). Developed areas in the park include the NPS Visitor Center and maintenance buildings, roads, private residences, and commercial buildings. Wetlands consist of 1881 polygons (77.1% of all polygons) and cover 8,148 ha (69.3% of entire area). Wetland areas consist non-vegetated areas such as the ocean, sound, and ponds in addition to vegetated polygons.Vegetation associations in the NVCS that are considered wetlands according to the U.S. Fish and Wildlife Service include the following: Maritime Red Bay Shrub Swamp, Coastal Loblolly Pine Wetland Forest, Atlantic Coast Stiff Dogwood Dune Swale, Atlantic Coast Interdune Swale, Groundsel-tree – Maritime Marsh Elder Tidal Shrubland Alliance, Seaside Oxeye Tidal Shrub Flat, Chestnut Fimbry – Common Threesquare Seasonally Flooded Herbaceous Vegetation, Southern Cattail – Giant Foxtail Herbaceous Vegetation, Tidal Sawgrass Marsh, Needlerush High Marsh, Reed Tidal Marsh, Southern Atlantic Coast Salt Marsh, and Mid-Atlantic High Salt Marsh.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Twenty-two map classes were developed to map the vegetation and general land cover of Cape Lookout and surrounding areas. These maps included the following: 13 map classes representing natural/semi-natural vegetation at the association level in the National Vegetation Classification System (NVCS), one map class representing cultural vegetation (e.g., developed) in the NVCS, and eight map classes representing non-vegetated units (e.g., open water bodies, buildings, roads, etc.). Features were interpreted using 1:12,000 scale digital color-infrared aerial photography (flown 31 May 2009) 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). A geodatabase containing various feature class layers and tables show the locations of vegetation types and general land cover (vegetation map), vegetation plot samples, AA sites, project boundary extent, and aerial photographic centers.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. A map showing the locations of vegetation map classes in the park was created, following the USGS/NPS Vegetation Mapping Program protocols (TNC and ESRI 1994a,b,c). A dichotomous field key was developed for these vegetation map classes to assist with field recognition and classification. The vegetation map covers 10,833 ha (26,769 ac) of Cape Cod National Seashore. The most abundant forest vegetation association is Pitch Pine - Oak Forest, which covers 1,756 ha (4,339 ac).

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 SECN contracted with Aero-Metric Inc., through the USGS Rolla, Missouri office to provide color infrared aerial photographs. Color infrared (CIR) imagery was chosen because healthy green vegetation is a very strong reflector of infrared radiation and appears bright red in color infrared imagery, which helps tremendously in vegetation mapping efforts. This set of photography covered the full project boundary extent plus a buffer surrounding the boundary of 500 meters. The flight path and centers of the aerial photo mission were planned with 60% forward-lap and 30% side-lap in order to assure stereo viewing. Airborne GPS data were provided by Aero-Metric, Inc, as were ground-check point data. The project was referenced to the North American Datum of 1983/2007 (NAD83/07), Universal Transverse Mercator Zone 17 horizontally and to the North American Vertical Datum of 1988 vertically. The aerial photographs were taken on 31 May 2009 at a scale of 1:12,000.

These data were converted from the originally delivered Microsoft Access PLOTs database from the Vegetation Mapping Inventory Project of Cape Hatteras National Seashore. These comma-delimited data tables contain(s) vegetation mapping plot classification and accuracy assessment data, as well as summary information about the data itself. If a table is empty, then it was empty in the original database.

A geodatabase containing various feature class layers and tables was constructed to show the locations of vegetation types and general land cover (vegetation map), vegetation plot samples, AA sites, project boundary extent, and aerial photographic centers. The feature class layer for the CUIS vegetation map provides 1,005 polygons of detailed attribute data covering 15,163.4 hectares, with an average polygon size of 144.7 hectares. Of the area mapped, 816 polygons (81% of all polygons) represent natural/semi-natural vegetation types in the NVCS, encompassing 9,542.8 hectares (62.9%) of the total map extent.
