Topographic map nomenclature

Nomenclature (map sheet title) of topographic maps depends on their scales. There is a list of standard scales of topographic maps below:

   - 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 1:10000 map looks like:

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

1 . 2 - 34 - 567 - 8 - 9 - 10 . 11

Dot or dash may be used as delimiter.

1 symbol. Means northern or southern hemisphere and

fccepts value:

0 - northern;

1 - southern.

2 symbol. «Latitude zone»  or Row (Latin character from A to U). Numbering is starting from equator

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

5,6,7 symbols.  Number of 1:100 000 map sheet (1-144) or number of 1:200 000 map sheet (1-36)

( 5,6 symbols accordingly)  or number of 1:500 000 map sheet (1-4) ( 5 symbol accordingly).

8 symbol. Number of 1:50 000 map sheet  on 1:100 000 map sheet

Accepts values from 1 up to 4.

9 symbol. A  scale 1: 25 000 map sheet place at an interchart (sheet division)

a scale 1:50 000 map sheet, accepts values

from 1 up to 4.

10 symbol. Number of 1:25 000 map sheet  on 1:50 000 map sheet, accepts values

from 1 up to 4.

11 symbol. Sheet type (latin charactecs A - D) can be one of following:

- single (A, B, C, D);

- double (A, C);

- four sheets in one (A).

Sheet type depends on latitude zones:

- zones A - O    - single sheet;

- zones P – S    - double sheets;

- zones T - U     - sheets «four in one».

Characters 8, 9, 10 depending on sheet type assigned following values:

1,2,3,4 if  single sheet

1,3 if double sheet

1 if «four in one» sheet

Character 8 is optional
