Projection is in NAD 83- units of measure in meters.
I have major roads NC vector data overlaid on Forsyth county in North Carolina.
Next, I converted the major roads raster from miles to meters using calculator (divided by 0.0006213). To find the cost surface, I input Forsyth county as source data, major roads raster as input cost raster, and I received an output cost map with unrealistically high values. If I can get help to find the correct cost map that would be great.
