Dear list, I have some very large geotiff-files (up to 10 GB) from satellite imagery that I need to load into QGIS. To speed up the rendering, I created pyramids on those images with gdaladdo. In QGIS 1.6 this worked very fine and the images where loaded (after adding them with "Add Raster Layer") within a few seconds.
Now, after I updated to QGIS 1.7, it takes several minutes to load the images into QGIS with "Add Raster Layer" (after being loaded, however, everything works fine and I can zoom in and out without any time-consuming rendering processes). Anyone has an idea why QGIS 1.7 takes so much time to load the images, as it was working fine in QGIS 1.6? I am using QGIS on Ubuntu 10.10 64bit. Hope someone can help Stefan -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/qgis-1-7-geotiff-problem-tp6486091p6486091.html Sent from the qgis-user mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
