The data inventory developed for the shoreline assessment 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 shore zone 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.
GIS coverages are developed from the GPS data sets collected in the field. The coverages use a shoreline base map 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 accompanies the coverages and defines attribute accuracy, data development, and any use restrictions that pertain to the data.
