At zoom 8 our area threshold for labels is 500,000,000 (was 200,000,000) and for polygons it's still 20000000.
Under the earlier system 5 meet the area threshold, but after only 2 do. So the changes here make sense to me.

This should be for low zoom tiles as well, so 8 > 0.

I'm seeing basin and dock label points very early still in London, and strait along the English Channel.
The full list of water kinds is:
basin, bay, canal, ditch, dock, drain, fjord, fountain, lake, playa, reef, river, riverbank, strait, stream, swimming_pool, water
But perhaps it's too brittle to have a full list (since values will come and go), when the measure should just be that we generated a label_placement for it at all?

Perhaps:
where: >-
(properties is not None and properties.get('label_placement') is True)

Also drop boundary which randomly appears when a river is also forms part of an administrative boundary.

This where clause doesn't seem to work.
There's another pattern we can switch to, like:
# no lake labels at zoom 0-3:
# https://github.com/tilezen/vector-datasource/issues/1730
- fn: vectordatasource.transform.drop_names
params:
source_layer: water
start_zoom: 0
end_zoom: 4
geom_types: [Polygon, MultiPolygon]

The larger range of min_zoom remappings is working for features are in the allowlist, woot!

Only the 'label_placement': True point should have names at this early zoom, and the min_zoom on that should probably be a different value besides 2 (like 7)?

Switched to geom_types param instead of where clause.

I expanded the list of kinds in this section based on QA where I saw low zoom basin, dock and straight points around London and the English Channel. Now it has every water kind.

Final QA over Sweden checks out, all remaining issues resolved. Ready to merge. |
|
two new failures: |
Closed
|
Those look like they should be updated, but don't show a problem with the new logic. Let's keep tracking that with #2038, but merge this now. |
