Hi All, I guess that many users work not only with WGS84 projection (which is set by default in QGIS) so I would like to discuss with you a change in QGIS behaviour on loading a layer.
In my opinion it would be good if QGIS: a) set the projection for a project file/working environment from the first loaded layer if it has the projection information b) prompt for projection information if the layer does not have it c) inform in a popup window when the projection of next loaded layers do not match the projection already set in the working environment (when reprojection on the fly is not ticked) Now, as I personally use metric reference systems (2180, 2176, 2177), every time I open a layer, I have to set the proper CRS and, on the other tab change units from degrees to meters. If I forget to do that, I will get strange scale and strange measurement output. At least the change form geographic to metric projection should force the change of units. Otherwise we won't be able to say that QGIS is user friendly ;) What in your opinion should be the most expected behaviour in a good GIS system? I mean in QGIS I can open now a holiday photo, go to layer properties and get an impresion from it's metadata, that it is already georeferenced: "Layer Spatial Reference System: +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs" which is of course not true. But we have to think about novice GIS users who might either go dizzy or get bad habits.
