Yes it is possible, the option "on-the-fly reprojection" does just that. Choose the main CRS as the project CRS (it will be used for distance calculations, etc.). Then when you add a layer you can choose its CRS individually, QGIS will do the transformation.<br><br>Regards,<br><br>Leyan<br><br><div><div id="SkyDrivePlaceholder"></div><hr id="stopSpelling">Date: Fri, 21 Sep 2012 09:08:05 +0200<br>From: joni8135@gmail.com<br>To: qgis-user@lists.osgeo.org<br>Subject: [Qgis-user] gfx in WSG 84 added to another CRS (EPSG:3021)<br><br>Hi.<br>I can transform gpx file from a GPS (WSG84) to an old swedisch CSR EPSG:3021 (RT90 2,5 gon V metric coordinate system)) shape file, but I whant to let the program transform on the fly.<br><br> I know that year 1999 Silicon graphic had it on there 'super coomputers' and GIS-softwate, and I also see that QGIS have under menue:<br>

Now Sweden is in transition from RT90 to SweRef99 (very near WSG84)<br>
<br>Is it possible to add vector files with other CRS, or even rasters to a project without transform it?<br><br>/Cheers<br><br>
