Hi @zahabia,
this version of component does not work anymore.https://discourse.ladybug.tools/t/why-my-terrain-generator-does-not-work/5138
You need to provide an API key to use Google API.
Could you test the new one and please make sure you have enabled correctly a Google Project and an elevation API service too.
Make sure that you do not receive a message like this:
Connect a panel to new version of component see response from service.
Otherwise, you can use JawgMaps. It is easy to set.
Regards,
Antonello
