Geographic map nomenclature (OGK)

The standard map sheet nomenclature is composed from the subsystem code or the Mid-latitude subsystem block, the scale code and the sheet number.

Codes of subsystems, Mid-latitude blocks and scales are as follows:

Subsystem (zone) or the

block Title (name)

Subsystem code

Scale

Scale coding code

The Mid-latitude

Subsystem Blocks:

Europe

Asia

Pacific ocean

Northern America

Atlantic ocean

Northern polar subsystem

Southern polar subsystem

Equatorial subsystem

Sheet number includes number of Longitude and Latitude zones, which intersection it is located on. Numbering of both zones starts at 0 and rises from bottom to top (Latitude) and from left to right (Longitude).

Nomenclature template looks like:

99 - 99 - 99 - 99

12 34 56 78

1 symbol . Means the block or the subsystem, accepts values

From 1 up to 8.

2 symbol. Means the scale, accepts values from 1 up to 5.

3, 4 symbols. Number of Latitude zone, Longitude zone of subsystem, accepts values from 00 up to 24.

5, 6 symbol. Number of Latitude zone, Longitude zone of the scale

1:10 000 000, 1:5 000 000, 1:2 500 000, 1:1 000 000 maps.

Accepts values from 00 up to 99.

7, 8 symbol. Number of Latitude zone, Longitude zone of the scale

1:1 000 000, 1:500 000. Accepts values

From 00 up to 11.
