Then, adjust the contrast of that layer Until all the water is black and the land is white, and adjust the brightness, until the coastlines look right.</li> <li data-xf-list-type="ol">Now, you'll have some left over bits -- labels and roads and such -- to clean up.  Just set the background color first to black and use cut box and eraser to clean up the water, then set the background color to white and do the same for the land. You should now have one layer with a basic outline with black water and white land, and another white background layer.</li> <li data-xf-list-type="ol">Use the magic wand to select the black area, and delete it.</li> <li data-xf-list-type="ol">Use the stroke function to outline the shoreline with a heavy black line (~4 or 5 pixels, location: outside, 100% opacity, Mode: Dissolve).</li> <li data-xf-list-type="ol">Stroke the shoreline layer again with a thin white line (1 pixel, location: outside, 100% opacity, Mode: Dissolve), and then again with a thin black line (pixel, location: outside, 90% opacity, Mode: Dissolve). Continue alternating 1 pixel wide white and black strokes...  all the white stripes should be at 100% opacity, but the opacity of each consecutive black line should decrease by 5% or 10% (Until you reach 0%). Using the Dissolve mode with the decreasing the opacity creates the dashed shading along the shorelines.</li> </ol></blockquote>
