C# Class SharpMap.CoordinateSystems.Projection

The Projection class defines the standard information stored with a projection objects. A projection object implements a coordinate transformation from a geographic coordinate system to a projected coordinate system, given the ellipsoid for the geographic coordinate system. It is expected that each coordinate transformation of interest, e.g., Transverse Mercator, Lambert, will be implemented as a class of type Projection, supporting the IProjection interface.

Method Details

EqualParams() public method

Checks whether the values of this instance is equal to the values of another instance. Only parameters used for coordinate system are used for comparison. Name, abbreviation, authority, alias and remarks are ignored in the comparison.

public EqualParams ( object obj ) : bool
obj	object
return	bool

GetParameter() public method

Gets an indexed parameter of the projection.

public GetParameter ( int n ) : ProjectionParameter
n	int	Index of parameter
return	ProjectionParameter

GetParameter() public method

Gets an named parameter of the projection.

The parameter name is case insensitive

public GetParameter ( string name ) : ProjectionParameter
name	string	Name of parameter
return	ProjectionParameter
