Hello, At Camptocamp we don't have any plan yet, but we are interesting in this subject.
The pbf mapnik-vector-tile seam to be a good chose :-) CU Stéphane 2016-06-19 10:10 GMT+02:00 Marco Hugentobler < [email protected]>: > Hi Nikolai > > Oh sorry, was reading the mail in a rush and meant raster tiles. > > I don't have much experience with vector tiles.
