Description:
Abstract:
This is a GIS data layer of polygons representing Submerged Aquatic Vegetation of Barnegat Bay - Little Egg Harbor, 1979, originally mapped by Robert T. Macomber and Dick Allen and digitized by the Grant F. Walton Center for Remote Sensing and Spatial Analysis (CRSSA), Rutgers University. Included are the submerged aquatic vegetation types mapped throughout the study area and their respective area and perimeter for each polygon.
Purpose:
The sav79.shp was created as part of the 'Landscape Scale Approaches to Coastal Habitat Conservation - Barnegat Bay' study. This study focused on the loss of submerged aquatic vegetation (SAV) that is occuring in Barnegat Bay as a result of human modification and decreasing water quality in the bay and watershed across time. CRSSA has compiled SAV studies conducted in the 1960's, 1970's, 1980's, 1990's to facilitate habitat loss assessment in Barnegat Bay. As of this writing, CRSSA continues to map and monitor submerged aquatic vegetation as part of its on-going Coastal Studies Program.

These maps as presented provide a regional picture of SAV distribution at various points in time and are not intended for site level permit applications or litigation purposes. These maps and data, alone, are not sufficient to determine the presence or absence of SAV. Conclusive evidence concerning the presence or absence of SAV requires site inspections, preferably at several points in time during the SAV growing season.

Data are supplied 'as-is' without warranty of any kind. While efforts have been made to ensure that these data are accurate and reliable within the state of the art, Rutgers University cannot assume liability for any damages, or misrepresentations, caused by any inaccuracies in the data. Rutgers University makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.

Any maps, publications, reports or any other type of document produced as a result of utilizing this data will credit the original map author(s) as listed as well as the Center for Remote Sensing and Spatial Analysis (CRSSA), Rutgers University.

Process_Description:
The digital source for sav79.shp is the Arc/Info coverage 'sav795m', which itself was originally an Arc/Info grid, rasterized at a five meter ground cell resolution in Arc/Info (ver 7.x) from the source vector GIS data for SAV raster GIS manipulation, analysis, etc. in Arc/Info 7.x and ERDAS IMAGINE 8.x at CRSSA. The source vector GIS data was generated at CRSSA by digitizing a paper base map series of submerged aquatic vegetation delineated and mapped on 1979 1:24,000 black and white aerial photography formatted/tiled to the 7.5 minute United States Geological Survey quadrangle series. The submerged aquatic vegetation was mapped by Robert T. Macomber and Dick Allen in 1979 and released as part of 'The New Jersey Submerged Aquatic Vegetation Distribution Atlas Final Report' (Macomber and Allen, 1979).
