Quantum GIS Training Manual, Release 1.0 A standard color dialog will appear. • Choose a grey color and click OK. • Click OK again in the Layer Properties window, and you will see the color change being applied to the layer. 3.2.2 Try yourself... Change the rural layer to a new color that you associate with rural farming areas. Check your results 3.2.3 Follow along: Changing symbol structure This is good stuff so far, but there’s more to a layer’s symbology than just its color. Next we want to change the color of the farms (the rural layer), but we also want to eliminate the lines between the different farms so as to make the map less visually cluttered. • Open the Layer Properties window for the rural layer. 18 Chapter 3. Module: Creating a Basic Map
Quantum GIS Training Manual, Release 1.0 Under the Style tab, you will see the same kind of dialog as before. This time, however, you’re doing more than just quickly changing the color. • Click on the Change... button below the color display: The Symbol properties dialog will appear. • Change the color inside the polygons in the layer by clicking the button next to the Color label (if you haven’t done so already during the previous lesson). • In the dialog that appears, choose a new color (that seems to suit a farm). • Click OK, but only once. Next, we want to get rid of the lines between all the farms. • Click on the Border style dropdown. At the moment, it should be showing a short line and the words Solid Line. • Change this to No Pen. 3.2. Lesson: Symbology 19
