 No-intersection edge detection. primem0ver11-Nov-17 6:19 primem0ver 11-Nov-17 6:19
 I am developing a project that is meant to improve feature smoothness in heightmaps that represent terrain from multiple maps at different resolutions from satellite imagery. I know how to use the data in the maps to detect the shorelines. What I want to do however is turn shorelines into edges (lines) that do not intersect at all so that I can smooth them from the blocky look they have outside the USA where satellite resolution is not as good. Most of the time this is fairly straightforward but the lack of good resolution on some of the height maps may result in islands touching the coastline. I want to make sure that the coast on the island follows the outline of the island while the main coastline stays the main coastline. Basically I believe this would boil down to making sure they don't intersect. This area of programming is completely new to me. I want to understand the best algorithm for 'untangling' intersections when more than one coast line happens to touch.
