Digital Shoreline Situation Report (SSRs) - Description and Disclaimer
The Comprehensive Coastal Inventory Program (CCI) at the Virginia Institute of Marine Science (VIMS) is generating new Shoreline Situation Reports (SSRs) for coastal localities in the state of Maryland. This effort compliments a parallel effort in Virginia by the same group. SSRs were developed by VIMS in the 1970s for Virginia and have been the foundation for shoreline management planning in Tidewater Virginia ever since. CCI has developed new protocols for collecting, disseminating, and reporting data relevant to shoreline management issues using state of the art mapping and remote sensing techniques. New SSRs are being generated on a county by county basis for Maryland and Virginia.
The data inventory developed for the Shoreline Situation Reports is based on a three-tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. Hand-held GPS units are used to log features observed. 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, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. Three GIS coverages are generated. The dorch_lubc coverage are features related to the land use in the riparian zone, and conditions at the bank. The dorch_sstru coverage includes information pertaining to structures for shoreline defense. Finally, dorch_astru identifies structures that 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.
GIS coverages are developed from the GPS datasets collected in the field. The coverages use a shoreline basemap generated in-house from digital orthophotography (DOQQs). The base shoreline is re-coded to reflect features and attributes observed in the field. The metadata file that accompanies the coverages defines attribute accuracy, data development, and any use restrictions that pertain to the data.
