Digital Shoreline Situation Report (SSRs) - Description and Disclaimer

The Comprehensive Coastal Inventory Program (CCI) at the Virginia Institute of Marine Science (VIMS) is creating a new GIS shoreline database to develop revised Shoreline Situation Reports (SSR) for Tidewater cities and localities. SSRs were developed by VIMS in the 1970s. These reports have been the foundation for shoreline management planning in Tidewater cities and localities for more than 20 years. CCI has developed new protocols for collecting, disseminating, and reporting data relevant to shoreline management issues of today. New SSRs are being generated on a county by county basis. This site will serve the data online as they become available.

The data inventory developed for the Shoreline Situation Reports are based on a three-tiered shoreline assessment approach. This assessment characterizes conditions in the shorezone observed from a small boat moving along the shoreline. Handheld GPS units record data observations in the field. The three tiered shoreline assessment approach divides the shorezone into three regions:

  1. the immediate riparian zone, evaluated for land use

  2. the bank, evaluated for height, stability and natural protection

  3. the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes.

Three GIS coverages are generated from the collection technique. The KW_lubc coverage are features related to the land use in the riparian zone, and conditions at the bank. The KW_sstru coverage includes information pertaining to structures for shoreline defense. Finally, KW_astru identifies structures which are typically built for access and recreational activities at the shore. They can be downloaded from this site through links at the bottom of this page. A metadata file is provided to describe each coverage.

The GIS coverages use a digitized 1:24,000 scale USGS high water line (HWL) shoreline as the baseline coverage. However, if the position of the digitized HWL differs greatly from the observed shoreline on a 1994 color infra-red digital ortho quarter quadrangle (DOQQ), the shoreline position is corrected to align more closely with the land-water interface observed in the DOQQ. Using ArcInfo, the base shoreline is re-coded with the attributes defined in each coverage.

These data are a product of the Comprehensive Coastal Inventory Program. The project was funded in part by the Virginia Institute of Marine Science, Comprehensive Coastal Inventory Program and the Virginia Coastal Resources Management Program at the Department of Environmental Quality through Grant Number NA77OZ0204 of the National Oceanic and Atmospheric Administration, Office of Ocean and Coastal Resource Management under the Coastal Zone Management Act of 1972, as amended.

The metadata file which accompanies these coverages defines attribute accuracy, data development, and any use restriction which pertain to the data. When downloading data from this site, the users agree to all conditions outlined in the disclaimer.
