MapProxy and TileCache don’t support them either. TileStache can produce vector tiles out of OGR datasource, but in GeoJSON format, which is way heavier than PBF, even gzipped.</div><div class="">So the good way to go would be to use the OGR MVT driver, but unfortunately it’s not released and the status of it’s development is unknown. While web is moving fast towards in-browser rendering (OpenLayers3 and Mapbox GL already utilise WebGL for that) it’s becoming clear QGIS server should support vector tiles at some point. Should I start with a feature request maybe?</div><div class=""><br class=""></div><div class="">Regards,</div><div class="">Nick</div><div class=""><br class=""></div>From: Marco Hugentobler <<a href="mailto:marco.hugentobler@sourcepole.ch" class="">marco.hugentobler@sourcepole.ch</a>><br class="">To: <a href="mailto:qgis-developer@lists.osgeo.org" class="">qgis-developer@lists.osgeo.org</a><br class="">Subject: Re: [Qgis-developer] Any plans for implementing vector tile<br class=""><span class="Apple-tab-span" style="white-space: pre;"> </span>generation on QGIS Server?<br class="">Message-ID: <<a href="mailto:5765066C.3000905@sourcepole.ch" class="">5765066C.3000905@sourcepole.ch</a>><br class="">Content-Type: text/plain; charset="utf-8"; Format="flowed"<br class=""><br class="">Hi Nikolai<br class=""><br class="">Most vector tile generators can work with any WMS in the background. <br class="">E.g. using MapCache with QGIS server should be perfectly possible.<br class=""><br class="">Regards,<br class="">Marco<br class=""><br class="">On 06/18/16 10:13, Nikolai Bezdna wrote:<br class=""><blockquote type="cite" class="">I’d like to know if there are any plans for enabling serving vector <br class="">tiles from QGIS Server, so they can be used in client libraries like <br class="">Mapbox GL afterwards.
