The map navigation is pretty much the same as many cartographic web sites:
- Move : put the mouse pointer on the map, then hold left button while dragging around.
- Zoom : use the magnifiers buttons or your mouse wheel.
This will show a screen divided in two sections: the first one is intended to reach a location by latitude / longitude, whereas the second allows you to search for a location name.
This second type of search can be restricted on the currently visible map (try the check box button for that). Moreover, you can specify the kind of location you are looking for. In this example, we are displaying only lakes.
