IFCCityJSON

Converter for CityJSON files and IFC. Currently only supports one-way conversion from CityJSON to IFC.

Dependencies

IfcOpenShell (also IfcOpenShell api is needed)
CJIO (>=0.8, <1.0)

Usage of IFCCityJSON

An extended ifccityjson tutorial can be found on the OSARCH wiki Following command will execute a conversion from CityJSON to IFC

python ifccityjson.py [-i input file] [-o output file] [-n name of identification attribute]

The example file that could be used is example/3D_BAG_example.json

python ifccityjson.py -i example/3DBAG_example.json -o example/3DBAG_example.ifc -n identificatie

Implemented geometries

TODO

CityJSON Attributes as IFC properties in 'CityJSON_attributes' pset
Implement georeferencing
Do not use template IFC for new IFC file, but make IFC file from scratch
Create mapping to IFC for all CityJSON object types & semantic surfaces
Implement conversion of all CitYJSON geometries
Implement conversion of all LODs instead of only the most detailed
