<br>
<a href="https://lists.osgeo.org/pipermail/qgis-user/2024-August/054721.html" rel="noreferrer noreferrer" target="_blank">https://lists.osgeo.org/pipermail/qgis-user/2024-August/054721.html</a><br>
<br>
And now the open data vector tiles of the Netherlands, do not work anymore in QGIS (in dutch):<br>
<a href="https://geoforum.nl/t/bgt-vectortiles-in-qgis-zijn-niet-meer-compleet/9731" rel="noreferrer noreferrer" target="_blank">https://geoforum.nl/t/bgt-vectortiles-in-qgis-zijn-niet-meer-compleet/9731</a><br>
<br>
Their conclusion is: in the standards the OGC winding order is different from the MVT winding order, that is why QGIS (thinking QGIS choose for OGC), is not rendering the MVT tiles anymore...<br>
<br>
So my question is:<br>
<br>
- anybody aware of changes of the winding order?<br>
- or do we do things 'better' now, breaking older functionality?<br>
- or are the pdok mvt tiles wrongly ordered?<br>
<br>
In the case of MVT tiles (haven't looked into the specs though), but it seems that the reader of the data would respect ordering differences between standards?<br>
