[Qgis-user] Difference results from QGIS project on fly and gdalwarp for EPSG:4326 of Sentinel 2 UTM zone 32?
Hello, I always thought QGIS and gdalwarp should return same result for projecting a 2D Sentinel 2 image (e.g: T32UQD_20200421T102021_TCI_60m.jp2) from UTM 32 to EPSG:4326. What I did was: - Open the .jp2 in QGis 2.14.9 (it has same problem with QGIS 3.12.2) with 'Enable on the fly CRS transformation'. - Warp the .jp2 to geotiff by gdalwarp: gdalwarp T32UQD_20200421T102021_TCI_60m.jp2 -t_srs EPSG:4326 4.warped.tiff And then open both T32UQD_20200421T102021_TCI_60m.jp2 and 4.warped.tiff on QGIS But the output results from them look different significantly (on the left hand side with QGIS it looks rotated and on the right hand side with gdalwarp it looks aligned). Illustration of differences: https://i.stack.imgur.com/Idisx.png *So, what should be the correct result? I cannot understand why they are different.More details described here: * https://gis.stackexchange.com/questions/360919/difference-results-from-qgis-project-on-fly-and-gdalwarp-for-epsg4326-of-sentin ___ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
[Qgis-user] Catalog OTF
I have a shapefile that contains essentially engineering drawing view ports and a path to the drawing in a field. I noticed that in QGIS 3.X there is a Catalog OTF tool/window and it picks up this layer. If I hit run QGIS starts using a lot of my cpu resources and I got tired of waiting so I terminated the process. So what is Catalog OTF? How do I use it? and What is it for? I could not find a tutorial on it or a description with some limited google searches.

[Qgis-user] Removing a layer name from the legend
Hi, In previous versions it was possible to remove the layer name by clicking edit on the legend item and deleting the text, as described in https://gis.stackexchange.com/questions/130625/how-to-remove-layer-names-from-the-print-composer-legend In master, deleting the text does not delete the layer, the text can be changed but not removed completely. Am I missing something? My use case: Design a 2 column legend for a single categorized layer with 4 categories. Currently, the left column consists of the layer name and two categories. The right column contains the remaining two categories but they are not well aligned with the category entries in the left column. This is because the items in the right column are aligned with the top of the layer name. To achieve a nice alignment, I would usually delete the layer name but now it seems that I can't.

I'd be interested to hear when this changed. But the "correct" way to remove the layer heading would be to right-click it and select "hidden".

Thanks, that's it. It would be awesome to have some indicator for the existence of this feature. Maybe an eye icon like in the composer item list?
