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

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

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

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
