Determines whether an area is above ground or not.
Area to determine whether is above ground
Returns AREA_ABOVEGROUND if the area oArea is above ground, AREA_UNDERGROUND otherwise.

The above/under-ground status of the area is set in the area's properties under the advanced tab.
AREA_ABOVEGROUND is declared as 1 in nwscript.nss, and AREA_UNDERGROUND as 0. So you could also say that the function returns TRUE if the area is aboveground, and FALSE otherwise.
