This
page is used to control the types of features that appear on the map, and which
type of features can be selected on the map.
- The Layer Categories are groupings of
related layers. These categories
are used to simplify the display of the layers. Click on the “+”
sign next to the Layer Category to see all of the layers in that category, or
click on the “-“ sign next to the Layer Category to hide all of the layers in
that category.
- Within each Layer Category, you may see
one or more map Layers listed.
Each layer is a different type of map feature that can appear on your
map. The checkbox next to each
layer indicates whether the features in the layer should be shown on the map.
If you want to hide buildings
from your map, for example, uncheck the box next to the Buildings layer and
then click on the Refresh link.
To make it available again, check the box and click on the Refresh
link. Sometimes the checkbox will
be disabled because the layer cannot be viewed at your current scale (some
layers can only be viewed at larger scales because they are relatively
inaccurate or cover large areas, and some layers can only be viewed at smaller
scales because they have a lot of features).
- The Legend shows what the map features
look like on the map.
