Hi!

 

I have a question that I can't figure it out myself.

 

I have a CityJSON (v1.0.1.) building data set which contain surfaces with type both "RoofSurface", "WallSurface" and"GroundSurface". How can I read or filter my data based on these types? Does FME support this when processing CityJSON, like it does for CityGML?

 

I have tried eg. to extract geometry parts and deaggregate buildings, but none of these helped.

 

Thank you a lot!

Hi @alpoturunen​,

You can use the GeometryPartExtractor to extract the parts of the geometry where the geometry Name = WallSurface, RoofSurface, etc.
