Imagery data for the Vegetation Mapping Inventory Project of Cape Hatteras National Seashore
공공데이터포털
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.

The Southeast Coast Network contracted with Aero-Metric Inc., through the USGS Rolla, Missouri office to provide color-infrared aerial photographs. The aerial photographs were taken on 31 May 2009 at a scale of 1:12,000. The calibration focal length for the photos was 152.823 mm. Contact prints of the CIR imagery were created for use in the field, and diapositives of the CIR set were created for photo-interpretation.

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. Cape Cod National Seashore contracted the James Sewall Company (Old Town, Maine) for fall “leaf-on” color infrared aerial photography in the fall of 2000. A flight plan chosen was identical to one used previously by the Commonwealth of Massachusetts Department of Environmental Protection Wetlands Program to produce photos at a scale of 1:12000. The plan allowed for the standard 60% overlap between frames and 30% overlap between flight lines resulting in stereo photo pairs for interpretation. Color IR (infrared) photography was chosen to maximize distinctions between green wavelengths in upland vegetation. Aerial photography was completed for the entire flight plan on October 4, 2000 and delivered as both positive transparencies and prints.

Geospatial data for the Vegetation Mapping Inventory Project of Cape Hatteras National Seashore
공공데이터포털
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.

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 photography was flown and processed by Photo Science Inc., of Gaithersburg, Maryland. In April 1993, stereo color-infrared aerial photos were collected in five flight lines, producing 215 9x9” diapositives. An additional inland series of 32 photos was also flown on the western shore of Sinepuxent Bay across from the park, but these were not used in this project. The original diapositive film is archived at the USGS Earth Resources Observation and Science (EROS) Center.
