Thnaks for taking the time to think about this. > There is a problem right now that some z12 tiles are built wrong. > Sometimes a land tile is colored as sea, and vice versa.

I created the first version of oceantiles.png and it was basically the output of my render script for the PGS data. The errors are primarly of the form: - coastline that was wrong in PGS obviously converted wrong and when someone fixed the uploaded coastline you get a difference. - oceantiles is misleading, since it also needs to register large lakes, since they also need to be blue. Any lakes not in PGS are thus wrong. - People shifting the boundary between the sea and the river leading to it. PGS was essentially computer generated and didn't know the difference, but when OSM mappers shifted the boundary of the coastline to near the coast it sometimes left a gaps of incorrect tiles. Distribution of the data was a problem considered at the beginning but never really solved. I'm glad you're thinking about it.
