There are some times when the libraries can run out of memory if a raster is very large, so you can have something that something like a graphics editor e.g Gimp can open OK but Qgis coujld have trouble opening it. On 17/06/22 14:22, Firstname Lastname wrote: I think that there is something wr

I think that there is something wrong with the Tif file I was using. I had the same problem with a couple of files but I went back to the source file and redid the referencing and it is ok. On Thu, Jun 16, 2022 at 7:46 PM Patrick Dunford via Qgis-user < qgis-user@lists.osgeo.org> wrote: > This i

This is a generic answer, as more information would be needed to determine exactly the situation you are experiencing. If you zoom to the layer, is it then displayed in the same place as the rest of your map? My recollection of the georeferencer is it produces a world file to go with the lay

Hi, Depending on what you are doing and what kind of results you are looking for, could you simply use "Polygonize" and then clean those results.  If your map are in RGB only, you could do a raster classification analysis before hand.  Line would follow pixels at first but those could be fixed

Hi, Look's like there's a problem with the georeferenced layer or perhaps the CRS or the coordinates of the base map. The first thing would be to look at the layer CRS to see if it's good.  Then, right click on that layer in the layer panel, go to Layer CRS and then select "Set Project CRS f

Once you start building a layout add your map frame. Make sure it's selected and to the right you should see the item properties panel for the frame. Scroll down and you'll see "grid" - that will let you add a grid with a different crs and different style of grids and tics. Disclaimer - I've ov
