I'm making a grad student making a deductive habitat, and I'm trying to figure out how can I go about removing roads from my habitat layer that I've constructed. What I'm saying is that I have a raster layer I've generated through various variables of potential habitat. I have another lines layer of roads. I'd like to remove any of the road area as potential habitat. I've tried rasterizing the roads from lines and then using map algebra to remove, but I'm not getting useful results. Perhaps I'm doing the map algebra wrong, but I feel like I've tried every possible combination. Any other ideas?
