Menu contains four basic items: for saving maps and file operations, selection map source, selection map resoution and creating selected area on map.

Map sources are grouped by their origin, for example all maps from the same web server are grouped into one submenu. If maps contains layers those are selected by checking particular menu item.

Save map to file is possible only if some part of map is selected. Selection mode can be activated from menu and after selection is done it must be deactivated. Selected area is created by clicking on the polygon points. It is possible to drag any point of the created polygon to change selection. Selection can be cleared with selecting menu item.
