A number of different kinds of ground cover were deemed potentially helpful for users of this map to locate and orient in the image above.
These features were captured as polygons and stored in a feature class called Locales. Several kinds of features were captured, including areas of open grass, parks, parking lots, and so forth. These features were captured after the block outlines were captured because in many cases some of the edges of the locale features were coincident with block edges. This allowed us to take advantage of the Editor's trace tool, to create the locale polygons quickly.
At one point it was thought that this map might be printed in large format and to add some extra detail trees were captured. The trees layer is included in the map document available in the data download. ArcGIS Desktop includes many cartographic TrueType fonts that contain marker symbols, including some for trees, which are in the ESRI US Forestry 2 font.
