The Tools menu provides commands for modifying, analyzing, and synthesizing images.
Parameters are the number and width of the contour lines.
If the input image is an elevation model, the result of the Contour Map command is an image showing equal-elevation contours. Each pixel from the input image is assigned to one of those classes. The spatial boundaries between the classes form the contour lines. The Shaded Relief command produces an artificially-shaded view of an original image. If the input image is an elevation model, the result of the Shaded Relief command is an image simulating a topographic view of the terrain.
