In this tutorial you will learn slope, aspect, contour and Hillshade map using ArcGIS. With the Surface tools, you can quantify and visualize a terrain landform represented by a digital elevation model (DEM).

Download DEM data:    • Digital Elevation Model (DEM) data of...  

Aspect: Derives aspect from a raster surface. The aspect identifies the downslope direction of the maximum rate of change in value from each cell to its neighbors.

Slope: Identifies the slope (gradient, or rate of maximum change in zvalue) from each cell of a raster surface.

Contour: Creates a line feature class of contours (isolines) from a raster surface.

Hillshade: Creates a shaded relief from a surface raster by considering the illumination source angle and shadows.
