At each place where you can select a map layer (eg for the base, or the overlay) you need to select a category first and then the map you want. Many maps have both a description (accessed via the "?" button), and a key (accessed via the key button). Every map can be excluded for a particular
OPS. More maps, and regions, will be added over time. Thanks are due to all suppliers.
