The utility MapList is created for simplifying the work with the topographic maps in OziExplorer format. Two problems appear when working with the large collections of maps. First problem is the map calibration, second one is the visual representation of the arrangement of the sheets. At present a large quantity of the scanned topographic maps can be downloaded from the Internet. Unfortunately, the significant part of these maps is not calibrated - i.e., it does not contain information about the position of sheet on the coordinate grid. OziExplorer allows calibrate maps manually, however, it is necessary to understand the essence of the question. Otherwise the difference in the coordinates on the map and the locality can reach hundreds of the meters. Furthermore, calibration requires accuracy and certain time. MapList substantially simplifies and accelerates this process. Parsing name of file, MapList determines scale and position of the sheet and create map file. Of course, the calibration points will not exactly fall into the map corners, however, after loading map into OziExplorer, it is possible to rapidly move its into the necessary place. Thus, it is not necessary any more to input coordinates of the calibration points and parameters of map projection. 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 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.
