I have converted two vector polyline datasets to raster format. One represents streams, and one represents roads. I need to create a third raster layer that contains cells where there are stream crossings.
I was going to use a simple boolean AND function to create a raster of stream-road junctions. However, at about 10% of the junctions, the raster lines intersect, but do not overlap. See the figure below.
Is there a tool or established method that edits the road raster to make sure that all road crossings actually have overlap with raster streams dataset?
