So i'm doing a project on coastal erosion. I have historical maps (1846, 1903, 1943) and also a present map, a map of the geology of the area (sands and gravel mainly), urban areas, lakes, woodland ect. From 1846 to present the coast (at the cliffs in Dunwich, Suffolk) has receded by about 105m (used the measuring tool in ArcMap 10.2.2).
I'm not the best at GIS, but I want to excel in this and have no clue how to go about it. A simple but sort of accurate approach would be preferred.
This answer is coming late but Keith VanGraafelland, Esri's Oceans Content Lead, will present a demo in the Technical Plenary at the 2017 Esri Ocean GIS Forum on detecting coastal change. His demo will be available as a video on Esri videos shortly (http://www.esri.com/videos).
