<p>QGIS when it opens a raster do not "attribute" any CRS, it just reads the CRS from the datasource, in this case the raster created by arcmap.</p>
<p>This is the CRS definition of the raster you attached:</p>
<p>+proj=omerc +lat_0=46.95240555555556 +lonc=7.439583333333333 +alpha=90 +k=1 +x_0=600000 +y_0=200000 +no_uoff +gamma=0 +ellps=bessel +towgs84=674.4,15.1,405.3,0,0,0,0 +units=m +no_defs</p>
<p>And this is the definition of EPSG 21781 - <a class="external" href="http://spatialreference.org/ref/epsg/21781/">http://spatialreference.org/ref/epsg/21781/</a></p>
<p>+proj=somerc +lat_0=46.95240555555556 +lon_0=7.439583333333333 +k_0=1 +x_0=600000 +y_0=200000 +ellps=bessel +towgs84=674.374,15.056,405.346,0,0,0,0 +units=m +no_defs</p>
<p>so no surprise that QGIS do not recognize it as 21781. So it seems you are right in the first place, is AM that do not use a standard definition.</p> QGIS Application - Bug report #14603: Wrong CRS attributed to a raster exported with ArcMaphttps://issues.qgis.org/issues/14603?journal_id=695852016-04-10T22:19:34ZJérôme Guélat
<ul></ul><p>Thanks for looking into this!</p>
<p>I agree that this is an ArcMap problem... but it is pretty annoying for people using both softwares in Switzerland. It also seems that other softwares using GDAL (R for instance) are able to apply the correct projection (or at least to show the data at the right place).</p>
<p>Then maybe this could be filed as a feature request instead of a bug. What do you think?</p> QGIS Application - Bug report #14603: Wrong CRS attributed to a raster exported with ArcMaphttps://issues.qgis.org/issues/14603?journal_id=702432016-05-23T06:16:02ZGiovanni Manghigiovanni.manghi@gmail.com
