Hello Lahmer Belkacem

Thank you for the data. I had a look at the DEM TIF you provided.

The issue is, that it uses a geographical coordinate system for georeferencing.

Unfortunately CityEngine only supports Cartesian coordinate systems for terrain layers.

Please export the DEM again using "WGS 1984 UTM Zone 31N" coordinates (same as OSM file) for georeferencing.

City Engine Help: Importing Georeferenced Data

"No reprojection nor rotation is applied to image data on import. The image's coordinate system is used only as reference system for location, extent and unit (translate and scale transformation) for the image data during import. It is therefore important to have image data ready in the target coordinate system before importing into CityEngine."

I have only a tiny bit of knowledge about CityEngine, but some general ideas about coordinate systems. Does the DEM have a defined coordinate system? There are ways that it could overlay in ArcMap without a coordinate system, but not work in CityEngine. What is the DEM's coordinate system?

Hi Lahmer,

I have the same problem with you. I alread georeferenced both the DEM and Building footprints in the same cordinate system named "WGS_1984_UTM_Zone_50N". Everything is ok when representing in ArcGIS. However, when I input those data into CityEngine, I got the same error that the data is located too far. Could you please help me to know how to solve this error?

Thank you very much.
