Question

gml_id and geometry issues in extending citygml 3


Badge +3

Hello everyone,

I am a beginner with CityGML and am currently trying to convert a dataset to CityGML 3 with generics extensions using FME Workbench. However, I am encountering a couple of issues:

  1. Warning about inheritance relationship: The output gives a warning indicating no inheritance relationship. I have used AttributeMerge to add gml_parent_id, but the system does not seem to recognize it.

<GML_2 Writer> - '12482' orphaned features found, XML comments representing these features will be present in the output file: <!-- orphaned feature - parent id:'...', id:'...', type:'...' -->

  1. Geometry export issue: It does not export correctly after setting up the geometry. In the Inspector, the data appears as a table without geometry.

Additionally, the original dataset complies with the CityGML 3 standard, and its geometry's encoding is Name (encoded: UTF-16LE). Could this encoding be affecting the process?

My settings and the transformer export are shown in the attached image.

I would greatly appreciate any help or guidance on resolving these issues.

Thank you in advance!

 

Jenny
