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).</P><P></P><P style="font-family: arial, helvetica, 'helvetica neue', verdana, sans-serif; color: #3d3d3d;">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.</P><P></P><P style="font-family: arial, helvetica, 'helvetica neue', verdana, sans-serif; color: #3d3d3d;">Thanks!</P></BODY></HTML> Thu, 31 Mar 2016 16:11:44 GMT https://community.esri.com/t5/spatial-data-science-questions/how-do-you-predict-coastal-erosion/m-p/640975#M1445 katiewarn 2016-03-31T16:11:44Z Re: How do you predict coastal erosion? https://community.esri.com/t5/spatial-data-science-questions/how-do-you-predict-coastal-erosion/m-p/640976#M1446 <HTML><HEAD></HEAD><BODY><P>Your first stumbling block...
