No transformation available: JGD2011 + JGD2011 (vertical) height

Hi there. I just started using citygml-tools to convert various CityGML data to CityJson. I am dealing with mainly Japanese building data and the CRSs are usually based on JGD2011. So, when I tried to reproject my Japanese data to a different CRS, I get following error message. I am guessing that the JGD2011 is missing from the library. PROJ 7.2.0 includes the Japanese
GSIGEO2011 geoid (https://www.osgeo.org/foundation-news/announce-release-of-proj-7-2-0-and-proj-data-1-3/).

Is there anyway you can include JGD2011 to reproject Japanese data to a different projection?

Thank you!!

This is an issue of https://github.com/citygml4j/citygml-tools and not of the specifications of CityJSON, I suggest you open an issue there.

An option is perhaps to convert to CityJSON and then use https://github.com/cityjson/cjio reproject operator?

HI @hugoledoux . You are right. Sorry about my posting here. I will contact to the citygml-tools community.
Thank you for getting back and your suggestion!!

Best.
