Am I seeing this right that the new Street-O tiles don’t have a transparent background anymore? That would be a pity, the old tiles made it possible to display a real Google-Hybrid lookalike with OpenStreetMap data.
Nevertheless, great work!
That's correct - the problem is the seas and oceans. Originally I was using a special shapefile for these, which had the seas around the UK filled in and "holes" for the land. Then I could set the map background to be transparent, and the sea area covered by the special shapefile to be blue.
However, I'm now using the standard processed_p shapefile for the world, where the land is filled in - so I set the background to be blue. However, to stop the land being blue as well, the processed_p layer content is set to white.
If anyone knows how to invert a polygon shapefile then the transparent tiles will be back!
For now, you can show the layer with 50% opacity, that should work quite well.
