[Qgis-user] Apparent bug or undesirable behaviour in QGIS (2.6.1/2.4.0)

[Trudgett, David]

The following behaviour manifests itself when adding a WMTS layer to a blank QGIS project.

When you add any WMTS layer and zoom to extent, what it actually does is zoom to the TileMatrixSet extent and not the layer. The layer is correctly advertising the WGS84BoundingBox but QGIS is ignoring it. If it used this value instead, zooming to layer for WMTS would make a lot more sense.

<Layer>
<ows:Title>Surat_Basin_Area.ecw</ows:Title>
<ows:Identifier>P1_Surat_Basin_Area.ecw </ows:Identifier>
<ows:WGS84BoundingBox>
<ows:LowerCorner>150.045708962027 -26.693037874264</ows:LowerCorner>
<ows:UpperCorner>150.447045150312 -26.243579854007</ows:UpperCorner>
</ows:WGS84BoundingBox>

So when you add, say, a layer in googlemapscompatible or globalcrs84pixel it will request the root tile index of the global tilematrixset, which for localized imagery will mean the dataset is rendered at the sub-pixel level (not shown!)

Is it possible to get QGIS to use the WGS84BoundingBox values?

David Trudgett
