Member Function Documentation

CacheArea()

bool TPG.Geoids.IGeoid.CacheArea	(	double	latmin,
		double	lonmin,
		double	latmax,
		double	lonmax
	)

Cache data from the externally supplied file for the entire region of interest. Recommended for speed optimization.

Parameters

latmin	Minimum latitude
lonmin	Minimum longitude
latmax	Maximum latitude
lonmax	Maximum longitude

Returns

Implemented in TPG.Geoids.Geoid.

Undulation()

double TPG.Geoids.IGeoid.Undulation	(	double	lat,
		double	lon
	)

For given latitude(lat) and longitude(lon), returns the geoid undulation (geoid height above the ellipsoid) at that point with respect to the wgs-84 ellipsoid.

Unless otherwise specified, calculations are based on the EGM2008 grid - using a 5' resolution.

Parameters

lat
lon

Returns

"geoid height above the ellipsoid, or double.NaN if invalid lat,lon

Implemented in TPG.Geoids.Geoid.
