However, if you are trying to create a realistic impression on your map, this symbology works against you. In the real world, we rarely see lines around areas, and the inside of those areas is rarely the same color everywhere. <!--more--><\/p>\n<p><img decoding=\"async\" src=\"http:\/\/downloads2.esri.com\/MappingCenter2007\/blog\/Feb12Images\/Polys_Intro_NoRealism.png\" border=\"0\" alt=\"Polygon Fill Symbols - No Realism\" hspace=\"5\" align=\"middle\" \/><\/p>\n<p><em>Figure 1.

That is a great solution, but in our next two blog entries, you will see how to use picture and marker fill symbols to add variation as well. You will also see how you can use cartographic representations to create fill symbols that do not clip at the edges of the polygons.<\/p>\n<p>This example is a map of southwestern Oregon in the Crater Lake area (figure 3). On this map, there are a variety of features to experiment with, including dry lakes, intermittent lakes and swamps\/marshes.<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/downloads2.esri.com\/MappingCenter2007\/blog\/Feb12Images\/Polys_Intro_SWOregonMap.png\" border=\"0\" alt=\"Polygon Fill Symbols - No Realism\" hspace=\"5\" width=\"600\" align=\"middle\" \/><\/p>\n<p><em>Figure 3.
