Re: [Geoserver-users] Vector-tiles: zoom-dependent generalisation

[Edward Mac Gillavry]

Hiya,

Thnx for your feedback. Indeed, we're working with the Mapbox vector 
tile format. Will investigate further whether the client library is 
actually requesting the tiles at the wrong resolution. Buildings are 
losing their right angles and disappear altogether at smaller zoom levels.


Cheers,

Edward

Hi,

Mapbox vector format is in integer-ized pixel coordinates, so doing 
more than that wouldn't affect the output.


For the other formats (i.e. geojson), you can use the 
overSamplingFactor so it gets better resolution.


If you need to change these, you're probably requesting tiles at the 
wrong resolution for what you're drawing.


Thanks,
Dave

Hi all,

Although 'Support on the fly geometry simplification' has been turned
off on the Store, there's still some kind of zoom-dependent
generalisation going on for vector tiles. Can the amount of
generalisation be adjusted for each zoom level? Is it the
overSamplingFactor? Can this be adjusted somehow as well?

Thanks in advance for your suggestions!

Cheers,

Edward
