Re: [Qgis-user] QGIS 3.22.2 import Mapinfo files

[SCHULZ Wolfgang]

Hello,
just to clarify - this was a problem on my side. I had to rename the files and 
the file names didn't match.
Sorry for the confusion and thanks for the fast reply
Wolfgang

Hi Wolfgang,

Normally I would advice you to create an issue for this on 
https://github.com/qgis/QGIS/issues
and attach a dataset with it, so other can confirm this is a QGIS issue (and 
not a mapinfo issue)

But to have a quick-fix, you could install an older (for you working) version 
of QGIS next to 3.22?
Another idea, if it is not too much data, ask others to convert your mapinfo 
files to geopackages or so? So you at least have the data?

(but please after you finished your project also create an issue (with dataset 
and expected outcome etc etc) so somebody can investigate.

REgards,

Richard Duivenvoorde

[Qgis-user] QGIS 3.22.2 import Mapinfo files

[SCHULZ Wolfgang]

Hello,
I'm importing Mapinfo files (*.mif + *.mid)  for years with all the QGIS 
versions. I recently upgraded to QGIS 3.22.2 (Win10) and realized that it is 
not working anymore. It seems that the *.mid file which is containing the data 
is not read at all because the attribute table is empty (the individual fields 
are there).
Is there another way to import Mapinfo files. What could be the reason for this 
issue?
Any help is appreciated.
The thing is that I need to finish a project today and I use this feature for 
the project.
Thanks a lot
Wolfgang

[Qgis-user] Win10 QGIS 3.2.2x64: Problem with number of colors for a raster image

[SCHULZ Wolfgang]

Hello,

I’m using QGIS 3.2.2 x64 on Win10 and I have a problem with the number of 
colors for a raster image if the modus is continuous (German Fortlaufend). How 
to increase the number of colors? Independent what I do I always have 5 colors. 
Is this a bug?

Best regards

Wolfgang

[Qgis-user] Import and reference HDF4 data

[SCHULZ Wolfgang]

Hello,
I want to import the following data (hdf format) into QGIS:
http://ghrc.nsstc.nasa.gov/hydro/search.pl?method=quick&keyword=HRFC&context=Any+field

Any idea how to georeference it?
I can import it. The interesting layer of the hdf4 file is the first layer. The 
layer should contain data -180 to +180 longitude and -90 to +90 latitude in 0.5 
degree resolution.
How can I tell to QGIS the limits of the data layer for a hdf4 file?

Thanks for your help
Wolfgang

[Qgis-user] PostGIS Layer

[SCHULZ Wolfgang]

Hello,
I'm using QGIS 2.2 (Win64) and want to add a PostGIS Layer. The data contains 
only points but with a lot of attributes. Is there a possibility not only to 
restrict the database request but to extract only some of the fields?

Thanks for your help
