Re: [Qgis-user] gridding with a polygon
Hi Byron As far as I can tell, you could create a negative sized buffer from the extent of the primary geologic dataset (use square and mitre results, not rounded, for buffering), then clip the primary dataset using the negative buffer to remove the unwanted zero contours.

Thomas Schüttenberg thomas at qgis.de Thu May 2 07:12:35 PDT 2024 All findings described below refer to QGIS 3.34.6. I am affraid it is connected to the extensive updates liste here https://lists.osgeo.org/pipermail/qgis-user/2024-April/054334.html ? Thu May 2 05:44:11 PDT 2024 "Unable to unzip file ''" is displayed and the project does not open. Hi Thomas, AFAIK the error message is displayed when the zip_open function of the libzip library, used by QGIS, fails to open the .qgz project file. Are there other related error messages in the Log Messages panel? Since you think the issue may be related to the recent OSGeo4W packages update, have you tried to downgrade the libzip library using the OSGeo4W Setup program to the previous version? Best regards.

Re: [Qgis-user] gridding with a polygon
Hi Byron: If I understand this correctly, you are concerned with how the contours will be generated at the edge of your raster data. If I have this correct, I would grid the data that you have based on the attribute you want to contour. Create a vector clip layer for your study area that is at least 1 grid cell smaller than the the boundary size of the original vector data. Then create the contours from this new raster and you should be good to go.

Re: [Qgis-user] QGIS 3.34 and QGZ on network drives
Update on "Unable to unzip file ''": This issue does not appear with QGIS 3.34.5. All findings described below refer to QGIS 3.34.6. I am affraid it is connected to the extensive updates liste here https://lists.osgeo.org/pipermail/qgis-user/2024-April/054334.html ? Anyway, still interested to hear, if someone experienced something similar.

[Qgis-user] QGIS 3.34 and QGZ on network drives
Hello everyone, I am currently preparing the rollout of QGIS 3.34.6 for our administration and have encountered a strange and very inconsistent behaviour when opening project files from our network drives (Windows): When double-clicking on such a project tile on the welcome page, the error message. "Unable to unzip file ''" is displayed and the project does not open. If you try it via the selection in the menu 'Project - Open recent' you get the same result. If you use 'Open project' (Ctrl+O) to open the Windows File Explorer and select the QGZ in question, it works. If you close the project and then click again on its 'Recent projects' entry on the welcome page or in the 'Recently used' menu, this also works now. However, if you wait a while (approx. 1-2 minutes) before clicking on a recent link, it does not work any more! The time can also elapse while the project is open, i.e. closing the project and then clicking on the recent link does not work (any more). First I thought, that saving or re-saving a QGZ with QGIS 3.34 would solve the problem, but today I encounter the same phenomenon on 3.34-QGZs, which I saved a few days ago. Furthermore, if the link to a project on the welcome page does not work and I then touch (i.e. single click) this qgz-file via the Windows file explorer, the recent link in QGIS works afterwards. User profiles or age or version of the QGZ do not seem to play a role. All of this cannot be reproduced with QGIS 3.28 using the same project-files. So, there seems to be a strange interference between QGIS 3.34 and the access to our network drives, which could become quite a blocker for our rollout. Only local QGZ are not affected. What do you think, has anyone heard of similar phenomena? I am grateful for any ideas!
