[mapserver-users] Status of MVT vector tiles?

[Miha Požauko]

I found that pull request before thanks, will play around with it some
more. When you say it relies on WMS requests does that mean it generates
raster tiles or vector tiles in PBD file format? I don't have mine mapcache
example working yet so i don't know what to expect.

About canceled requests i found related "issue" discussed on leaflet forum:
https://github.com/Leaflet/Leaflet.VectorGrid/issues/136
But i don't see a problem with that because all entities are loaded on my
map.

I will have to find that secret souce yes, will try to optimize my map file
for different scales. Pregenerated vector tiles would also help.

Thanks for your answers. Will track your github for further updates.
