DataSets[Builtin][WorldMap]

  

SetProjection

  

specify the default projection for a WorldMap object

 

Calling Sequence

Parameters

Description

Examples

Compatibility

Calling Sequence

SetProjection(m,proj);

Parameters

m

-

a WorldMap object

proj

-

the name of a projection, optionally including parameters if applicable

Description

• 

The SetProjection command sets the default projection of m.

• 

This projection is the one that is used by default when calling Display, and when printing a world map object. It is also the projection that is considered when using ResetView.

• 

proj must be the name of a valid projection (see the full List of Projections), optionally including parameters if applicable (for example, CylindricalEqualArea(37.5)).

Examples

mDataSets:-Builtin:-WorldMap

mPLOT...A map of the worldprojection: MillerCylindrical

(1)

When the map is displayed after setting the center, it now uses the LambertAzimuthalEqualArea projection.

SetProjectionm,LambertAzimuthalEqualArea

PLOT...A map of the worldprojection: LambertAzimuthalEqualArea(0,0)

(2)

This projection is also the one now used by default with the Display command.

Compatibility

The DataSets[Builtin][WorldMap][SetProjection] command was introduced in Maple 2017.
