C# Class MapAround.Geography.GnomonicProjection

Gnomonic projection. This class, unlike MapAround.CoordinateSystems.Transformations.Gnomonic, is designed for internal use.

Public Methods

Method	Description
GetCenter ( IEnumerable points, double &centerLat, double &centerLon ) : void	Calculates the longitude and latitude of the projection center for an array of points on the ellipsoid.
GetCenter ( double latLonSequence, double &centerLat, double &centerLon ) : void	Calculates the longitude and latitude of the center of projection to the passed values of latitudes and longitudes.
GnomonicProjection ( double centerLongitude, double centerLatitude ) : System	Instantiates GnommonicProjection.
Project ( double latitude, double longitude, double &x, double &y ) : void	Calculates the coordinates of the point in the projection plane.
Unproject ( double x, double y, double &lat, double &lon ) : void	Calculates the latitude and longitude points.
