  12. Select each of the rectangles on the selection layer which represent buildings.
  13. Make sure black is your foreground color. Select the new layer. Now go to Edit ¦ Stroke Selection.
  14. Select Stroke Line, with a Line Width of 4, and select Solid Colour.
  15. Now click on Stroke. A thick black line will appear along the line of all your selections. This will depict the area near buildings and roads that collects dirt and grime, also an element of shadow.
  16. Make this look more real now by blurring the line. First remove your selection by going to Select ¦ None.
  17. Go to Filters ¦ Blur ¦ Gaussian Blur. Leave the settings as default (5 pixels) and select OK.
  18. Now reduce Layer opacity to 30%. You can see the effect, subtle but important, in the next image:

What just happened?

You just learned how to create and manipulate selections in GIMP to add shadow or fill areas with texture. The shadow/dirt effect is subtle but important, as you will now see in your map texture. It has more feeling of depth, doesn't it?
