HOW TO
The Slope tool can be used to create a slope map by identifying the slope from each cell of a raster surface. Contour lines are usually presented as line features in a shapefile or feature class (vector data). However, a slope map cannot be created directly from contour lines because the Slope tool does not support vector data as the input.
The instructions provided describe how to create a slope map from contour lines.
Note: The Topo to Raster and Slope tool require a Spatial Analyst or 3D Analyst license.
