int lwgeom_calculate_gbox_geodetic ( const LWGEOM geom,
GBOX gbox 
)

Calculate the geodetic bounding box for an LWGEOM.

Z/M coordinates are ignored for this calculation. Pass in non-null, geodetic bounding box for function to fill out. LWGEOM must have been built from a GSERIALIZED to provide double aligned point arrays.
