Nomenclature of topographical map

Previous Top Next

Nomenclature (map sheet title) of topographic maps depends on their scales. The following scales of topographic maps exist:

- 1: 1 000 000,

- 1: 500 000,

- 1: 200 000,

- 1: 100 000,

- 1: 50 000,

- 1: 25 000,

- 1: 10 000.

- 1: 5 000.

 

Template of Nomenclature of 1:10 000 map looks like:

9 . Z - 99 - 999 - 9 - 9 - 9

1 . 2 - 34 - 567 - 8 - 9 - 10

 

Dot or dash may be used as delimiter.

1 symbol means northern or southern hemisphere and accepts value:

0 - northern;

1 - southern.

Symbol 2 denotes "Latitude zone" or Row (Latin character from A to U).

3,4 symbols. "Longitude zone" or Column (Integer from 1 to 60). Numbering is starting from meridian of 180 degrees.

Accept the values from 1 to 60,  increasing in the direction of the east.

Symbols 5,6,7 denotes the number of the map sheet of scale 1 : 100 000. If the map sheet of scale 1 : 1 000 000, accepts values from 1 to 144.

If the map sheet of scale 1 : 200 000, accepts values from 1 to 36 (respectively 5,6-th symbol).

If the map sheet of scale 1 : 500 000, accept values from 1 to 4 (respectively 5-th symbol).

Symbol 8 - a location of a map sheet of scale 1: 50 000. At ruling a map sheet of scale 1:100 000, accepts values from 1 to 4.

Symbol 9 - a location of a map sheet of scale 1: 25 000. At ruling a map sheet of scale 1:50 000, accepts values from 1 to 4.

Symbol 10 - a location of a map sheet of scale 1: 10 000. At ruling a map sheet of scale 1:25 000, accepts values from 1 to 4.

 

Examples of nomenclatures of topographic maps are given in the table 1.
