Hi list! (Apologies in advance for the embedded image, I couldn't write this post sensibly without it).
I had a novel request this week for calculation of buffers which respect obstacle geometries. Given input features (the red dot below, but could also be line/polygon features), and a layer of "obstacles" (the blue line, but could be either lines or polygons), then the buffer must respect the obstacles and not be allowed to cross over the blue line. Ie the desired result is the red shaded area in the attached image. Every point in the buffer should be within the buffer distance of the original geometry by paths which don't cross any of the obstacle features. There's some prior related discussion at https://gis.stackexchange.com/questions/390958/buffering-with-obstacles Is this something which could potentially belong in JTS / GEOS? Is it even possible? And if so, is it something my customer could fund the development of? Cheers, Nyall
