Hi,
I have just started by learning how to use Bluekenue and Telemac 2D.

I plan to merge 5 models to make a single model on BlueKenue. But I have a projection problem. Three of my models are in Lambert 93 and two others in Lambert III.
I would like to reproject them to have them all in Lambert 93 but I don't know how to proceed. I've tried to do it on qgis before bringing them to BlueKenue but it doesn't work.
I would be very happy if someone could tell me how to proceed.

Thanks

Good morning Soniel,
As it was mentioned just before you can use python scripts to project your slf file.
Whenever you want to do pre-treatment on selafin file, you can check in the notebooks or directly in the python scripts included in TELEMAC-MASCARET.
For your problem, you can just use this command:
"run_telfile.py alter input_file outputfile --proj="EPSG:xxxx/EPSG:xxxx" --force"

The first xxxx should correspond to the EPSG of Lambert III and the second or Lambert 93.

Best regards,
Jean-Paul
