Abstract
The data inventory developed for the Shoreline Inventory is based on a three tiered shoreline assessment approach. This assessment characterizes conditions that can be observed from a small boat navigating along the shoreline or by using observations made remotely at the desktop using high resolution imagery. The three tiered shoreline assessment approach divides the shorezone into three regions: the immediate riparian zone, evaluated for land use the bank, evaluated for height, cover and natural protection the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. The 2015 Inventory for Middlesex County was generated using on-screen, digitizing techniques in ArcGIS&tm;- ArcMap v10.2.2 while viewing conditions observed in 2015 Bing high resolution oblique imagery and 2013 imagery from the Virginia Base Mapping Program (VBMP). These data sources allowed the inventory to be generated without additional field work. Three GIS shapefiles are developed. The first describes land use and bank conditions (Middlesex _lubc_2015). The second reports shoreline structures that are described as arcs or lines (Middlesex _sstru_2015). The final shapefile includes all structures that are represented as points (Middlesex_astru_2015). The shapefiles use a shoreline basemap updated in-house from the 2013 VBMP high resolution digital terrain model. The shoreline is re-coded to reflect features and attributes observed. The metadata file accompanies the shapefiles and defines attribute accuracy, data development, and any use restrictions that pertain to data.
