Water areas emerging from the sea are not displayed #728

Open Rub21 opened 5 months ago

Rub21 commented 5 months ago

Water areas emerging from the sea are not showing; most of them are bordered by coastlines but do not appear on the map. This seems to be a data issue, or it would be good to also check the map styles. It appears this occurs in many places.

waterareas_vsLandandOcean

Confirming that I believe this is a data issue - the data doesn't exist for some of these water areas (see above gif) - some polygons for this water area exist (see gif) but is not for entire area

I have been adding some water bodies around Brazil, using OSM data as a basis. I think we can create a task in TM to ask the community for help, or at least we can work on the most important lakes and deltas that are missing.
