wmm_location_t

Geographic location type.

Synopsis:

typedef struct  {
    double latitude_deg ;
    double longitude_deg ;
    double altitude_meters ;
}wmm_location_t;

Data:

double latitude_deg
Degrees north of equator (Geodetic) [-90,90].
double longitude_deg
Degrees east of IERS Reference Meridian [-180,180].
double altitude_meters
Meters above earth reference ellipsoid.

Library:

libwmm

Description:

This structure describes a spot on the Earth with respect to a reference ellipsoid. Currently, the WGS84 ellipsoid is used. More precise ellipsoids may be used in future models.

Note that additional conversions are required to find AMSL (Above Mean Sea Level) or AGL (Above Ground Level).
