Hi,<br>I notice the add of the Polyhedral Surface to GML.<br>It is very interesting.<br><br>But I have a little question:<br>see-ing the code I notice the srsDimension of posList is ="2".<br>I will think the correct value was "3".<br>
Certainly the value of coordinate used are of a 2D dimension.<br>But I don't understand why a Polyhedral surface must have a definition on a 2D universe.<br>Or it is the 2D envelope of a Polyhedral Surface ?<br><br><br>
