Mathematical elements for maps of scale 1 : 1 000 000

I. Geographic coordinates grid.

Meridians are drawn by direct lines:

         through 1 ° from 0 ° up to 64 °

         through 2 ° to the north of (to the south of) 64 ° parallel.

Code - 13110000, type (character of localization) - line, characteristic - 19. Geodetic coordinates - longitude L.

Parallels are drawn through 1 ° (everywhere).

Parallels are represented by broken lines with points of a break in places of crossing with meridians.

Code - 13120000, type - line, characteristic - 19. Geodetic coordinates - latitude B.

Dashes of meridians lines on sheets are drawing:

through 10 ' from 0 ° up to 64 °

through 20 ' to the north of (to the south of) 64 ° parallel.

 Code - 13430000, type - line, characteristic - 19. Geodetic coordinates - longitude L. Length of dashes - 4 mm. Dashes divisible by 30 ° from 0 ° up to 64 ° and divisible by 1 ° to the north of (to the south of) 64 ° parallel are drawn by length of 6 mm.

Dashes of parallels lines are drawn through 10 ' everywhere.

Code - 13440000, type - line, characteristic - 19. Geodetic coordinates - latitude B. Length of dashes  - 4 mm. Dashes divisible by 30 ' are drawn by length of 6 mm.

II. Rectangular (kilometer) grid.

Rectangular grid is designated through 2 cm by pieces of lines from an internal frame. Length of a piece is 2,5 mm. For every 6 ° zone the own system of rectangular coordinates is given.

Vertical lines.

Code - 13210000, type - line, characteristic - 17. Rectangular coordinates - Y.

Horizontal lines.  

Code - 13220000, type - line, characteristic - 17. Rectangular coordinates - X.
