Example 17. It is often difficult to blend two different gridded data sets on one map. A solution is to use coastline clipping. Here, a geoid grid is imaged in color, before pscoast is used to initiate clipping, followed by a gray-shaded topography. Note that both images fill the entire map, but the coastline clipping only lets the images show where we want them to be valid.
