Hello R people I want to create a buffer around shapelines that would go around obstacle like shown in that figure:
https://www.dropbox.com/s/8qhkj6atkfllzky/unreachable_buffer.jpg Here is the idea: I have field teams that cannot walk more than 1.5 km away from a road. I need to know what part of the territory is accessible and what part isn't. I cannot do a simple buffer as the other side of the lake isn't really accessible by walking. Anybody knows if it's possible to do in R? It's been done a couple of years ago in ArcINFO but we can't know how because the code is hidden. However it was using raster, so it's maybe a hint of a solution. Any ideas would be greatly appreciated! Thanks! Bastien Ferland-Raymond, M.Sc. Stat., M.Sc. Biol.
