Passport Parameters Classification

NOTES:

1. Generalized Map Type:

1 - Topographic,

2 - General Geographic,

3 - Special Space Navigation,

4 - City Topographic Plan,

5 - Large-Scale Site Plan,

6 - Aeronautical,

7 - Nautical Navigation,

8 - Aviation;

9 - Blank Chart.

The dependency between the map type and other passport characteristics is as follows.

Map Type:	Topographic	General Geographic
Ellipsoid	Type Krasovsky	Krasovsky
Vertical Datum	Baltic Sea	Baltic Sea
Projection	Gauss-Krüger	Other than Gauss-Krüger
Coordinate System	1942 System (SK-42)	Rectangular
Frame Type	Trapezoidal	Depends on projection

Map Type:	Space Navigation
Ellipsoid Type	Krasovsky
Vertical Datum	Baltic Sea
Projection	Special Cylindrical
Coordinate System	Not Defined
Frame Type	Rectangular

Map Type:	Topographic Plan	Large-Scale Plan
Ellipsoid Type	Krasovsky	Krasovsky
Vertical Datum	Baltic Sea	Baltic Sea
Projection	Gauss-Krüger	Not Defined
Coordinate System	1942 System (SK-42)	Local
Frame Type	Rectangular	Rectangular

Map Type:	Aeronautical
Ellipsoid Type	Krasovsky
Vertical Datum	Baltic Sea
Projection	Conformal Conic or Simple Modified Polyconic
Coordinate System	Local for each sheet
Frame Type	Trapezoidal

This classification of passport parameters is not exhaustive and may be supplemented in the future.

2. Coordinate System:

1 - 1942 Coordinate System (SK-42, Rectangular),

2 - Universal Transverse Mercator (UTM) System (USA),

3 - National Grid of Great Britain,

4 - Local Rectangular Coordinate System (for large-scale plans),

5 - 1963 Coordinate System (SK-63),

6 - Conventional Rectangular for overview maps; depends on the projection type, values of the standard parallels, and the central meridian.

7 - Geodetic coordinates according to the ellipsoid type.

3. Vertical Datum:

1 - Baltic Sea Height System (zero of the Kronstadt tide gauge);

6 - Mean Sea Level in the English Channel (Great Britain);
