[Qgis-developer] Unknown CRS problem

Agreed, even (apparently) simple changes can have unexpected consequences. The discussions on this topic have been very interesting, but back to the point. At present, QGIS reports the CRS of a layer whose projection it cannot determine as the QGIS default CRS. It would be very helpful if the CRSs of such layers were reported by QGIS as 'unknown'. At present, right-clicking on a layer and going Properties -> General can produce downright wrong information on the CRS of the layer and I think this is undesirable.

Hi! definitely correct .. speaking of my own experience it's not just keeping the data without the .prj files .. I've also seen a lot of companys (including governments) sending shape files just as the ".shp" And i always wonder how ArcGIS is the job of correctly open the files .. but thats another story .. still hope that raster reprojection on the fly will work soon! good luck and many thanks to radim for doing that job!! regards Werner Am 11.01.2011 09:19, schrieb Paolo Cavallini: Il giorno mar, 11/01/2011 alle 00.43 +0100, Martin Dobias ha scritto: Ideally if all the data from government is in the same CRS, no reprojecting will happen - because the project CRS will be the same as the CRS of individual layers (thus no warning would be issued).

Even though reprojection is expensive, it's probably better to reproject the layer than to render it misaligned :-) Anyway reprojecting every single point using the coordinate transform formulas wastes a lot of processing power and should be done more wisely.

I'm concerned that such a warning could scare newbie users who don't know about spatial reference systems at all (and it will be one of the first things they see if the datasource crs is not recognized.

I don't think that they do. Which ever option is selected there are problems. If the user doesn't know the CRS for the layer or if QGIS can't determine the CRS for the layer the result is confusion either way. To be honest, this isn't a problem for me because I know just enough about CRSs (and the need never to trust them without checking) to get me through. The trouble is that newcomers to QGIS get confused when things don't work as they expect and it's very easy for them to mutter something like "typical open-source" and walk away from it. They can't understand why, when they right-click on a layer and go Properties -> General, QGIS might tell them something that is downright wrong about the layer CRS.
