Belgium: parcels
Hi,
I have a few questions on providing (Belgian) parcel data:
-
Is this a supported feature or still in beta ? The documentation (https://github.com/openaddresses/openaddresses/blob/master/CONTRIBUTING.md) still mentions
Valid layers are addressess. In the near future parcels and buildings will be supported
But there are already a few parcel sources available, so I assume we can just mimic what e.g. Canada is doing ?(https://github.com/openaddresses/openaddresses/blob/master/sources/ca/bc/port_moody.json) -
I assume the structure/source does not have to follow the structure of the addresses (ie.: the Belgian addresses are provided by the 3 Regions, but the parcel are published by the federal level as 1 single nation-wide source)
-
Is there a size limit per source ? The compressed download is a 2.5 GB zip with Shapefiles (8 GB uncompressed)

@ingalls has built support for parcels so you can add them now. Documentation still needs to be updated, feel free to put forward a PR for the docs if you'd like to help.

You can have a separate countrywide.json
file just containing the parcels, it doesn't need to be in the same json file for each region which contains the addresses.

You can try. I uploaded a 1GB zip for au/qld parcels.
drafting updated docs at #5542
Thanks, I'll give it a try early next week.
Looks like the shapefile containing the Belgian parcels also contains other layers (e.g. administrative borders), so I'll have to ask them to make a separate set containing just the parcel data...

The system can download the whole thing and pick just the parcels. It'll take less time if they are broken up, but it should be possible.
Ah that would be great... but if I read the documentation correctly, the layer
property is currenly only supported for GDB, not for shapefile ?
Since each shapefile is a "layer", you can accomplish the same thing by specifying file
when processing Shapefiles.
Makes sense, thanks.
And contrary to what I first thought, the zipped file contains a separate shapes for each region, so it could somewhat follow the same structure as the addresses...
