runs.geojson doesn't include connection pistes

[rodrmoya]

Connection pistes (piste:type=connection) provide the connections between lifts and ski
runs, but are missing in the runs.geojson.

Been trying to test a patch to include them, but been unable to run the data processor, running
always into an out of memory exception:

This happens even when selecting a smaller dataset via the BBOX env variable.

Hi @rodrmoya, it makes sense, I think I tested out connections at one point but decided to not include them because I didn't find a good visualization.

I suspect the OOM issue might be due to your BBOX="[0.5253, 42.5893, 0.6092, 42.541]" - the bottom latitude is above the top, that might cause the bbox to ignored. The project doesn't easily work for the whole world anymore due to the high memory usage.
