The trick used in VirtualPlanetBuilder is to drop a curtain down from the edge of the tile. This hides the gap rather than fixing it. There are other techniques that require using multiple LOD's along the edges to match the triangulation, or to dynamically set up the edge to match but all a far more complicated than the curtain approach.
