Constructor & Destructor Documentation

Geoid()

TPG.Geoids.Geoid.Geoid ( string  file, bool  cubic, bool  threadsafe  )

inline

Constructs a geoid based on supplied data, with optional initial cacheing.

Parameters

file	Full path of supplied egm file
cubic	true, for cubic interpolation. Otherwise jus bilinear
threadsafe	If true, all data will be cached initially. Should not be used for 1' resolutions

Member Function Documentation

CacheArea()

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

inline

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

Implements TPG.Geoids.IGeoid.

Undulation()

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

inline

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

Calculations are based on the EGM96 grid - having a 5' resolution.

Parameters

lat
lon

Returns

Implements TPG.Geoids.IGeoid.
