QGIS Vector Tiles – Filtering OpenInfraMap Vector Tiles by Layer Name in QGIS

openstreetmapqgisvector-tiles

When I load the OpenInfraMap vector tile service in QGIS 3.28.1 (https://openinframap.org/tiles/{z}/{x}/{y}.pbf), how can I filter the data by layer name?

OpenInfraMap uses different layers as we can see in the TileJSON file.

Unfortunately, the Vector Tile Reader plugin doesn't work anymore with OpenInfraMap.
I get the following error: The field 'vector_layers' is required but not found. This is invalid TileJSON.

Sometimes you can't see the forest for the trees! The answer was so near. We can filter the layer directly in the layer properties symbology dialog:

2 years later but I've had some success doing what I think you want done using the tile-join tool in mapbox tippecanoe. It's opensource.

https://github.com/mapbox/tippecanoe#tile-join

Tile-join is a tool for copying and merging vector mbtiles files and for joining new attributes from a CSV file to existing features in them.

It reads the tiles from an existing .mbtiles file or a directory of tiles, matches them against the records of the CSV (if one is specified), and writes out a new tileset.

If you specify multiple source mbtiles files or source directories of tiles, all the sources are read and their combined contents are written to the new mbtiles output. If they define the same layers or the same tiles, the layers or tiles are merged.

    r = requests.get(url)

    # ------------------------Decryption------------------------
    response = r.content
    decoded_data = mapbox_vector_tile.decode(response)

Import relevant modules to your sript, parse the URL to your specific tile at specific zoom level for example;

https://abc.com:8080/buildings/16/4059/6568.mvt

Here 16/4059/6568 are zoom level X and Y numbers of your requested tile id. After that you can print decoded data to see the decoded JSON of your tile.
