Yep, at https://github.com/boostorg/geometry/blob/develop/include/boost/geometry/extensions/algorithms/dissolve.hpp . It might be worth trying to work this in.

@TimSC Now that we've got support for riverbank-style multipolygons, I've been encountering a few edge-cases with Clipper. Sometimes the 'hole' disappears from the multipolygon: I've encountered this for the islands...

Heh - nothing's ever simple... For a quick demonstration: https://map.canal.travel, you'll see the blue lake to the right of the built-up area in Oxford. At z12 it's fine (it doesn't...

https://github.com/systemed/tilemaker/commit/a748b9ef96705664a44697834ea88634515fd3a7 included a fairly comprehensive rewrite of the OpenMapTiles-compatible config.

Thanks! Feel free to leave issues for anything that you think could be improved (or even better, patches :) ).

We're writing house numbers to the layer as documented in the OpenMapTiles schema (https://openmaptiles.org/schema/) - that doesn't have a height value so I guess they'll always appear on ground level....

I think there might be a Windows compatibility issue here. Unfortunately I don't use Windows or have access to a Windows system, so I'm afraid you're probably on your own...

The default style with tilemaker is designed to be compatible with the OpenMapTiles schema. So the question is really a) is the greenery data in OSM in the first place;...

Good thinking. It looks like Boost.Geometry does have a point_on_surface implementation as well.

Interesting question! Small-scale landcover is often done from external datasets (e.g. CORINE, ESA Landcover, Global Land Cover 2000), which in some cases need to be vectorised from a raster original....
