Is the receivers::Delaunay_grid function very very slow? about noisemodelling HOT 7 OPEN

Hi,
Can you give us more details, in particular which tutorial you used ? Are you talking about this one ?

from noisemodelling.

You probably put a veryyyyy short propagation distance? Did you change some default parameters ?

Ok. I guess you followed the tutorial Noisemap from point source ?
If so, I just repeat the exercice and I takes less than 1s to produce the triangulation

Maybe your problem comes from the SRID associated to the input files ? This dataset has to be 2154 (french legal one)

I did it with reference to this example

Can you upload your files

from noisemodelling.

Hi,
I used:

• buildings.shp which is in the folder .../NoiseModelling_4.0.2/data_dir/data/wpsdata/
• Point_Source.geojson, which is in the folder .../NoiseModelling_4.0.2/data_dir/data/wpsdata/TutoPointSourceDirectivity/

If you try with your own dataset, you just have to be sure that both files are in the same (metric) projection system
