Hi all No there's no standard about non-Webmercator usage of vector tiles. TileJSON spec. leaves open how CRS is handled which was a wise decision. So it's up to us to come up with a proposal.
But what's bad is, that TileJSON is not even up-to-date to describe vector tiles. At least MBTiles spec. recently got updated to 1.3. I'm a bit frustrated about Mapbox having "no time" not even to update the MVT specs. It's just delaying innovation. :Stefan 2018-02-13 10:39 GMT+01:00 Even Rouault <even.roua...@spatialys.com>: > On mardi 13 février 2018 02:06:47 CET jratike80 wrote: > >> Even Rouault-2 wrote > >> > >> > On lundi 22 janvier 2018 23:40:55 CET Even Rouault wrote: > >> >> Hi, > >> >> > >> >> > P.S. @Even: Any news on a GDAL/OGR MVT reader? > >> >> > >> >> Yes, a new OGR MVT reader has just been committed in GDAL trunk: > >> >> http://gdal.org/drv_mvt.html > >> > > >> > And the writer part (for MVT and MBTILES) driver is now in trunk > >> > > >> > http://gdal.org/drv_mvt.html > >> > http://gdal.org/frmt_mbtiles.html > >> > > >> > Even > >> > >> Hi, > >> > >> At the moment we create MVT tiles from PostGIS with ST_AsMVT to suit with > >> the national gridset that is based on ETRS-TM35FIN (EPSG:3067) coordinate > >> system.
