Hi, what does this mean? E:\citygml-tools\citygml-tools-1.4.0>citygml-tools to-cityjson FZKHouse.gml [22:14:36 INFO] Starting citygml-tools. [22:14:37 INFO] Initializing application environment.

It simply means that citygml-tools cannot automatically derive the EPSG code from the string urn:adv:crs:ETRS89_UTM32. You can pass the EPSG code manually using the --epsg paramter (see citygml-tools to-cityjson --help). So, in your case, use the following command:

$ citygml-tools to-cityjson --epsg=25832 FZKHouse.gml

Many thanks. This removed the error but did not include the information from the GML. Is Energy ADE export supported? And if yes, what is the correct procedure? many thanks

No, the CityGML Energy ADE is not supported by default. There is no "Energy Extension" defined for CityJSON, so how should the energy data be mapped by citygml-tools?

citygml-tools is built on top of citygml4j. Thus, if citygml-tools should support a specific CityGML ADE, then you need a citygml4j module for this ADE. In case of the Energy ADE, there is in fact such a module: https://github.com/citygml4j/energy-ade-citygml4j. You have to put the module into the ade-extensions folder of citygml-tools, then it will be automatically loaded when running citygml-tools. All CityGML-related operations will then account for the Energy ADE data.

If you want to be able to also map a CityGML ADE from and to CityJSON, then you need the following in addition:

  1. A CityJSON schema mapping the ADE to a JSON representation
  2. A CityJSON extension module for citygml4j

There is no schema and no module so far.
