Anderson, M.G.; Judd, C., and Marcoe, K., 2012. Rapid characterization of shorelines using a georeferenced video mapping system.

Mapping shoreline resources is crucial for coastal planning, yet current approaches are limited in ability to characterize remote areas or detect small features. Documentation using video mapping may provide a rapid and repeatable method for assessing the current state of the environment and determining changes to the shoreline over time. In this publication, we compare two studies using boat-based, georeferenced video mapping in coastal Washington and the Columbia River Estuary to map and characterize coastal stressors and shoreline condition. The coastal Washington study in Clallam County was completed in 1 day and covered a distance of 70 km, whereas the Columbia River Estuary study was conducted over a 10-day period and covered 1030 km. In both areas, multiple features were mapped along the shoreline. The position and orientation of the camera allowed for characterization of vertically oriented features such as shoreline armoring, and smaller features such as pilings and large woody debris. These types of features could not be consistently detected using traditional aerial photo interpretation. In addition, end users noted that the georeferenced video provides a permanent record to allow a user to examine recorded video anywhere along the boat transect.
