GOM - the Global Overlay Mapping System

An Overview of Available Maps

An easy to way to see which maps are available in the Global Overlay Mapper, to find out their coverage, and to select them with a single click, is contained in the Overview page. To load this, click 'Locate > Overview' on the main toolbar.

The page that opens shows 2 world maps; the upper, smaller one for the 8 continental maps, and the lower, larger one for the 29 sub-continental maps. To see the available maps, move your cursor over the screen. As you do so, the coverage area of the map will illuminate in green, and the map-information (name and borders) will be displayed in the box below. To select any map, simply click on the green area.

The one map that can't be selected in this way is the World Map. To select this, click 'World' on the main toolbar.
