City of Suffolk, Virginia: Digital Shoreline Inventory Report
Description and Disclaimer
The Comprehensive Coastal Inventory Program (CCI) at the Virginia Institute of Marine Science (VIMS) is generating new Shoreline Inventory Reports for coastal localities in Virginia. This effort compliments a parallel effort in Maryland by the same group. Documents known as Shoreline Situation Reports 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. The new Shoreline Inventory Reports are being generated on a county by county basis for Maryland and Virginia, and describe conditions along their tidal tributaries to the Chesapeake Bay. This series is published entirely in digital format.
The data inventory developed for the Shoreline Inventory 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. 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. GPS registered videography was used to collect data on conditions observed in the field.
Three GIS shapefiles are developed from the GPS field files. The first describes land use and bank conditions (Suffolk_lubc). The second reports shoreline structures that are collected as arcs or lines (Suffolk_sstru). The final shapefile includes all structures that are represented as points (Suffolk_astru).
The shapefiles use a shoreline basemap generated in-house from the Virginia Base Mapping Program’s high resolution digital terrain model from 2009 and 2011 (where available). The shoreline is re-coded to reflect features and attributes observed in the field. The metadata file accompanies the shapefiles and defines attribute accuracy, data development, and any use restrictions that pertain to data.
