Plugin not working with latest LTS 3.34.x #2

Open gcapnias opened 7 months ago

The plugin returns with an error on QGIS v3.34.4 - Error: Algorithm saga:polygonselfintersection not found.

I presume the error is due to the new SAGA provider.

Trying to search about the issue Copilot come out with this, which I do not know if it stands:

  • To address the 'Algorithm saga:polygonselfintersection not found' error in QGIS when using the 'Buffer Without Overlaps' plugin, follow these steps:\n\n1. Ensure that SAGA is installed in your QGIS.\n2. If you have installed SAGA Next Generation, change the algorithm ID from 'saga:polygonselfintersection' to 'sagang:polygonselfintersection' in your Python code.\n3. Try running the plugin again after making this adjustment."

Hello George

I downloaded version 3.34.3 of QGis, and verified that it is not necessary to make any changes to the plugin "Dissect and dissolve overlaps" Ver: 0.3, which works correctly with this version of QGis if the adjustments indicated in the file "saga4qgis.zip" (attached) are made. This file is contained in the SAGA GIS version 9.3 installation ZIPfile "saga-9.3.1_x64.zip".

The instructions contained in "saga4qgis.zip" can be a little complicated to follow, so I attach this instruction file with some notes written by me.

If, after these adjustments to QGis 3.34, the plugin does not work correctly, please contact me.

Best regards, Antonio Almeida

Hi Antonio,

For some reason I did not receive the attachment. Can you please point me to the page you download the file with the changes for the SAGA GIS?

Thanks, George J.

Hello George

The readme text in the the file "saga4qgis.zip" just say this:

The generated tool interface makes it possible to use this SAGA version in QGIS.

*SUMMARY:

You can download saga-9.3.1_x64 from this link:
