Oops, including the list. Also, having now written the response and re-read your question, I would guess that the coordinate system you are using is causing the distortion you see in the result. I'd be curious to see what others on the list might suggest as the best option for crs as I think

Hi Aqshems, To help move this along, I'd recommend opening a fresh qgis instance, making a new user profile, and then dragging in your data source and rebuilding the symbology. If you get what you expect without any problems, I would then copy the layer and paste it into the original qgis file.

Glad it worked out! As long as you rename every file in the shapefile renaming shoukd be fine. Renaming just the .shp file will cause problems. You might consider: http://switchfromshapefile.org/ Thanks to whoever on this list shared that originally. On Wed, Aug 23, 2023, 2:20 AM Gómez

Hi Sandra, When you say "data" are you referring to spatial data saved in something like a shapefile geopackage etc, or the actual qgis file ending in .qgz or .qgs? If it is the actual qgis file itself that you are seeing corrupted, I would not expect a qgis file created by a newer version to be

Hi Martin, I don't use grass with qgis much but I do have a guess. When you look at your installed programs, is it possible there are options for "qgis" and then also a listing specifically for "qgis with grass". Different operating environments might explain why you can't import from grass as

Hi, the two things I would try are 1, Saving the file as a .qgs file instead of .qgz and 2, saving to a simple filepath like desktop or downloads if you are not doing so already. It might also be worth trying to save the file to a geopackage instead of as a stand alone file. On Fri, Jul 28,

Thanks all for the conversation and helpful thoughts. I finally had time this morning to read through and try things in qgis. For a polygon or multipolygon in the symbology settings, the random Marker fill seems to meet the need well. That should save me a lot of time! Have a good weekend all.

Hi all, Sometimes when working with data, especially points, I'll have a stack of several points in the same location, usually when the accuracy of the x/y values is low. In a lot of cases, if I'm selecting a point in a "stack" it will not appear selected since it's covered by another point. My

to follow up as I continue to work on this, I mistakenly understood the attribute type "binary" as a Boolean, but I think it's in fact an arbitrary value stored as binary. That is to say, not necessarily True/False or 0/1 but a series of 0/1's storing a value. If I can save it to the shapefile
