Re: [Qgis-user] hide vector under raster?
Hi, If you are having crashes, try on 2.18 to see if you have the same problem. Are you using on the fly reprojection? If your vector file is not in the same format as the raster, the reprojection is probably taking all the time. Try saving in an other format like spatialite that is more efficient than shp. Copy the file on a local disk and not a file server. Make a new project with only the raster and the vector files to make try and isolate the crash problem. Disable all plugins. Perhaps the control rendering order in the layer order panel can help? Not sure, I don’t use that.

There's no difference between no symbols and simple renderer.

Re: [Qgis-user] hide vector under raster?
Hi Tobias, I did not really get what you want to achieve. Let me put it in my words (this is what I understand) 1) You have a vector layer with _many_ features 2) You do not want to have it rendered because it takes so long to render 3) You want to query this layer 4) When you zoom out QGIS crashes when using the no symbols renderer Questions: What kind of layer is this: DataProvider? geometryType? Which version of QGIS are you using? Does QGIS crash when zooming out while you use a simple renderer?

Hi! How about using the no symbols renderer in the style tab in Layer properties? Wouldn't that do? Regards Karl-Magnus Jönsson -Ursprungligt meddelande- Från: Qgis-user [mailto:qgis-user-boun...@lists.osgeo.org] För Tobias Wendorff Skickat: den 29 maj 2018 13:08 Till: qgis-user@lists.osgeo.org Ämne: [Qgis-user] hide vector under raster? Hi there, is it possible to hide a vector layer under a raster layer? The "click through" identify function allows to query data from the vector, but on each zoom the vector layer gets rendered completely again. Sure, it makes use of an spatial index, but since there are many vector elements, it takes a while. I tried to hide the vector layer using visibility at fixed scale, but then it's not possible to query it...
