C# Class SharpMap.CoordinateSystems.Projections.LambertConformalConic2SP

Implemetns the Lambert Conformal Conic 2SP Projection.

The Lambert Conformal Conic projection is a standard projection for presenting maps of land areas whose East-West extent is large compared with their North-South extent. This projection is "conformal" in the sense that lines of latitude and longitude, which are perpendicular to one another on the earth's surface, are also perpendicular to one another in the projected domain.

Public Methods

Method	Description
DegreesToMeters ( SharpMap lonlat ) : SharpMap.Geometries.Point	Converts coordinates in decimal degrees to projected meters.
Inverse ( ) : IMathTransform	Returns the inverse of this projection.
LambertConformalConic2SP ( List parameters ) : System	Creates an instance of an LambertConformalConic2SPProjection projection object. The parameters this projection expects are listed below. ItemsDescriptions latitude_of_false_originThe latitude of the point which is not the natural origin and at which grid coordinate values false easting and false northing are defined. longitude_of_false_originThe longitude of the point which is not the natural origin and at which grid coordinate values false easting and false northing are defined. latitude_of_1st_standard_parallelFor a conic projection with two standard parallels, this is the latitude of intersection of the cone with the ellipsoid that is nearest the pole. Scale is true along this parallel. latitude_of_2nd_standard_parallelFor a conic projection with two standard parallels, this is the latitude of intersection of the cone with the ellipsoid that is furthest from the pole. Scale is true along this parallel. easting_at_false_originThe easting value assigned to the false origin. northing_at_false_originThe northing value assigned to the false origin.
LambertConformalConic2SP ( List parameters, bool isInverse ) : System	Creates an instance of an Albers projection object. The parameters this projection expects are listed below. ParameterDescription latitude_of_originThe latitude of the point which is not the natural origin and at which grid coordinate values false easting and false northing are defined. central_meridianThe longitude of the point which is not the natural origin and at which grid coordinate values false easting and false northing are defined. standard_parallel_1For a conic projection with two standard parallels, this is the latitude of intersection of the cone with the ellipsoid that is nearest the pole. Scale is true along this parallel. standard_parallel_2For a conic projection with two standard parallels, this is the latitude of intersection of the cone with the ellipsoid that is furthest from the pole. Scale is true along this parallel. false_eastingThe easting value assigned to the false origin. false_northingThe northing value assigned to the false origin.
MetersToDegrees ( SharpMap p ) : SharpMap.Geometries.Point	Converts coordinates in projected meters to decimal degrees.
