The CFDT is an automated computer vision application designed to generate 3D line features representing the seacliff top, midpoint, and toe on high-relief coastal cliffs. The program also delineates 3D points on concavities and convexities across the cliff face (termed subsidiary features), which may represent talus deposits, secondary cliff tops, and secondary cliff toes. The tool package includes algorithms for automatically generating alongshore baselines (the Baseline Builder), determining landward/seaward direction, and casting cross-shore transects with little or no user intervention. The application is freely available as a script tool for Esri ArcGIS Desktop version 10.6/10.7, and generated 3D shapefiles can be reviewed in ArcGIS, converted to traditional cross-shore elevation profiles, exported as text tables, or manipulated in a 3D viewing environment such as Esri ArcScene.

Cliff Feature Delineation Tool and Baseline Builder version 1.0 user guide
Coastal cliffs constitute 80 percent of the world’s coastline, with seacliffs fronting a large proportion of the U.S. West Coast shoreline, particularly in California. Erosion of coastal cliffs can threaten infrastructure and human life, yet the spatial and temporal scope of cliff studies have been limited by cumbersome traditional methods that rely on the manual interpretation of seacliff featureAuthorsAlexander C.
