Many users of OziExplorer accumulate a large quantity of the maps, but it is not always possible to say quickly, is there a map of one or other region. Definitely, you can use function "Find map at cursor" in OziExplorer. But it is much more convenient to create coverage track on the existing maps with MapList, and then load it into OziExplorer above the index map. So, it is possible to clearly see coverage of a region and even to determine the scale of maps. For example, the screenshot below clearly shows map sheets of scales 1 : 1 000 000, 1 : 500 000, 1 : 200 000 and 1 : 100 000.
