Concretely, if you have the geographical coordinates, for example, 48.231554 (lattitude) or 35.736298(longitude),and you need to define the range of maps - the list of nomenclature:

1: 1 000 000 M-36
1: 500 000 M-36-4
1: 200 000 M-36-36
1: 100 000 M-36-144
1: 50 000 M-36-144-1
1: 25 000 M-36-144-1-4

This feature can be useful for surveyors, GIS-specials and, may be, just students.
