I would like to create a continuous raster that is a buffer around a polyline in ArcGIS. For example, lets use a maximum buffer distance of 20m.
At a 20m distance from the line, the raster value would be 0; At a 0m distance from the line (i.e. right on top) the raster value would be 1; At a distance of 10m from the line, the raster value would be 0.5; At a distance of 5.25m from the line, the raster value would be 0.2625;
I realize I could create multiple buffer polygons around the line, then convert to raster and normalize, but is there any easier way to do this that also allows for a more continuous raster?
