PolygonPatch builder

Hi,

 

 

GML MultiSurface can be created from an aggregate feature with the GeometryExtractor. I'm wondering if it can be modified into GML Surface through some XML and/or String operations.

 

 

Or, use the GeometryExtractor to create GML Surface for each single polygon; extract PolygonPatch element form the resulting Surface; and then construct the required GML Surface that contains multiple PolgyonPatch elements.

 

 

Anyway, some transformers in the XML category might help you.

Takashi,

 

 

I already made Surface using this approach in PythonCaller. But it is 'slow' because it uses string concatenations, xml fragmentation and so on.

If there is no FME built-in transformer, I'll optimize mine a little bit more.

Thanks anyway!

Python is also good, but I think XML transformers are also worth to try.

 

e.g.

 

 

 

XQuery Expression parameter (XMLXQueryUpdater)

declare namespace gml='http://www.opengis.net/gml/3.2';

 

<gml:Surface>

 

<gml:patches>

 

{//gml:PolygonPatch}

 

</gml:patches>

 

</gml:Surface>
