[Qgis-user] GTiff compression issues
Hi, I am using QGIS to try and compress hi-res drone imagery. I am using GDAL tools, such as 'Clip Raster by Extent' . In the command line parameters I am adding the following: -co COMPRESS=JPEG -co TILED=YES --config GDAL_TIFF_INTERNAL_MASK YES. The original image is RGBA. Compression is significant (which is what I need) and visually there is not much of a difference. However, when zooming further in (1:200), I noticed that some raster cells have turned white. When inspecting, it appears that the compression is changing the data of one or more of the bands to nodata. How can this be resolved? I am using QGIS 3.10.8 Thanks Yury Zammit ___ 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] Error: unsupported locale setting
Hello,
I am not sure when this happened but I am getting this error for the HCMGIS
plugin. I am running QGS 3.10.8 on Windows 7.
Here is the python message

Re: [Qgis-user] Loss of data
Windows has a feature called previous versions. Locate the shape files on explorer, look for the dbf file, right click, properties and see if you have any previous versions that you can restore.

Re: [Qgis-user] Installation of QGIS 3.4 continually crashes
An update, and this is really really weird. So a colleague of mine save a QGIS3 project on our work network. If I double click on it, then I manage to open QGIS 3.4. I copied it on my PC and I managed again to open the project in QGIS3 by double clicking. Then if I close, and try to open QGIS via the Start menu, it crashes. Why? Would really like to solve this.

Yes it is in a separate directory. Tried 3.8 via osgeo and same thing happened. On Tue, 2 Jul 2019, 13:22 Phil Wyatt, wrote: > Hi Yury, > > Are they installed in seperate directories?

I cannot get QGIS 3.4 LTR to work on my PC. I have QGIS 2.18 installed and it works fine. But after I installed 3.4 and started the program, it crashes on the splash screen, just after *Starting Python *shows up. Help me please!
