GeoJson with multiple feature collections

diffmarc — Fri, 08 Dec 2023 15:24:41 GMT

Hello,

I want to create a data pipeline for a public geojson, which contains multiple feature collections, with different geometry types.

The resulting feature layer should only contain one of said collections.

Is it possible to filter for this?

For the moment, when I built a data pipeline for the geojson file, I get only one of the feature collections into my layer, but it is always the very first one (which I unfortunatly don't need).

Thanks a lot.

Hi Romain,

Thanks for the question!

Can you share a link to the public data so we can investigate the structure? Is it a single file, with a top-level array of feature collection objects? Such as:

[ {"type": "FeatureCollection", "features": []}, {"type": "FeatureCollection", "features": []} ]

Best,

Max

Hello Max,

thank you for replying.

This is the the link to the collection: https://download.data.public.lu/resources/plan-cadastral-numerise-pcn/20231211-045325/pcn.geojson

The data is structured the following way:

{"layer1":{"type": "FeatureCollection", "features": []},

"layer2":{"type": "FeatureCollection", "features": []},

...}

Best,

Romain
