Function gaiaGeodesicArea

Source 
pub unsafe extern "C" fn gaiaGeodesicArea(
    geom: gaiaGeomCollPtr,
    a: f64,
    b: f64,
    use_ellipsoid: c_int,
    area: *mut f64,
) -> c_int
Expand description

Measures the total Area for a Geometry object (geodesic)

\param geom pointer to Geometry object \param a major axis of the reference spheroid. \param b minor axis of the reference spheroid. \param use_ellipsoid if TRUE will measure the Area on the Ellipsoid, otherwise on the Sphere \param area on completion this variable will contain the measured area

\return 0 on failure: any other value on success

\sa gaiaGeomCollLength, gaiaMeasureArea, gaiaGeomCollArea

\remark \b LWGEOM support required.
