Multipolygon Empty in "ground_geometry" for WG484 (4326) Data

[BenitThinot03]

Hello,

I have imported this CityJSON with EPSG:4326 into the CJDB database, and I see that the "ground_geometry" is not displayed correctly; it gives "EMPTY MULTIPOLYGON" instead. When I try the same CityJSON with EPSG:7415, it works perfectly.
What can be the issue.
I am using the CJDB version 2.10.
Here are the files I am working with.

denhag4326.json
denhag7415.json

I don't know why the geometries are empty, but EPSG:4326 is a 2D CRS (in degrees) and you have your z-values in meters.

It is never a good idea for 3D modelling to mix units for the 3 axis, those should be the same: You have now lat-long in degrees and meters, the solution to this is to use a projected CRS like EPSG:7415.

You could try to put the correct CRS and see what happens:
EPSG:4979
WGS84 (EPSG:4326) + height in meters
