So I have an Image Mosaic Coverage store for the whole country, from this I have published 2 layers with restricted bounding boxes - A & B in this image:
[image: tiles.png] These are distinct layers and when requested in QGIS they only display what is in the declared native bounding box. When I place the two layers in a Layer Group so I only need to add one layer in QGIS, the declared bounds are ignored and data for the whole of the layer group bounds is returned (possibly in both layers?) What I expected GeoServer to do was extract the required data from Layer A and a Layer B draw it as a single image and return it to QGIS with nothing in between the two layers. This is all vanilla GeoServer with no GeoFence added (though I have thought of trying that next).
