  • My scenario is that I have to ensure that all polygons going through a process have fewer than 2000 vertices. These polys can vary in size and complexity quite significantly. Districts, towns, counties...

I'm trying to build an expression in Generalizer's'tolerance' setting that address this in every scenario (I have a Tester for node count beforehand, so this will only have to deal with polys with 2000+ nodes). I assume it's related to the perimeter but I'm not getting very far.

 

Any suggestions gratefully received

 

Thanks

@paulc1​  Chopper has the option to break polygons by vertex count. There is also a GridChopper on FME HUB that is useful for areas with a large extent

You could use the looping function in a customer transformer to slowly increase the generalisation? This might avoid trying to build a 'smart' expression​.

ooh....good call.....
