<div>is type 0 for LWGEOM occupied by anything or could it be an idea to use it for empty geometries. </div>
<div>Then it would be easy to create any emtpy geometry. Like a generic empty geometry.</div>
<div> </div>
<div>Or is there another way that I have missed.</div>
<div> </div>
<div>When I have identified the empty geometries, in shortestline and it buddies I need to communicate that an empty geometry should be returned and the datatype is LWLINE and LWPOINT for st_closestpoint. I'm tempted to just make an LWGEOM with type 0. Is it a bad idea. </div>
<div> </div>
<div>#define EMPTY 0</div>
<div>#define POINTTYPE 1<br />
#define LINETYPE 2<br />
#define POLYGONTYPE 3</div>
<div>and so on</div>
