Re: [Qgis-user] SAGA Next Gen for MacOS
Hello Lorenzo, Thank you for your help! I tried both QGIS 3.30.x and 3.32, but I do not have Providers under Processing. QGIS 3.32 has SAGA Next Gen plugin already installed, but it is version 7.2, not 7.8 as you say, and it still says "Requires manuaö installation of SAGA 7.2 binaries." I installed SAGA 9.0.2, and it is a standalone software package. I suppose that I could perform the analyses in SAGA 9.0.2, export the results in geotiff, and import them into QGIS to continue working, if I cannot get SAGA Next Gen work as a plugin inside QGIS. My Mac is old (7-8 years old), not the newer Apple processor. Thank you for your help!

Re: [Qgis-user] SAGA Next Gen for MacOS
Hi Etsuko Inside QGIS 3.30.x for macOS there are still the old libraries of SAGA version 7.8 and so the SAGA Next Gen plugin works without providing any paths. I use this system. If, on the other hand, you want something more such as using SAGA 9, the latest version, where there are many new algorithms, you need to download SAGA for Mac, currently 9.0.2, directly from the SAGA website: https://sourceforge.net/projects/saga-gis/files/SAGA%20-%209/SAGA%20-%209.0.2/ It is a normal application that you drag into Applications. Then in QGIS inside Processing > Providers > SAGANG > SAGA folder enter the path: /Applications/SAGA.app/Contents/MacOS Press OK and you have all the algorithms in the latest version of SAGA 9: QGIS works fine. For those who have the Apple Silicon processor, however, better install QGIS3, currently 3.28.7, from MacPorts. QGIS3 is native with all the native external libraries (including SAGA, GDAL, Grass, etc.) and the performance is spectacular.

[Qgis-user] Measuring Map Rendering Time using PyQGIS
Hi,
I am looking for a way to audit a QGIS projects in terms of layer rendering
time.
I was able to measuring the rendering every time I refresh the the map
canvas, change layers or change extent, using the following code (inspired
by Anita code):
from datetime import datetime
def get_time():
t1 = datetime.now()
print('Rendering time:',t1-t0, 'seconds')
def reset_time():
global t0
t0 = datetime.now()
canvas = iface.mapCanvas()
canvas.mapCanvasRefreshed.connect(get_time)
canvas.extentsChanged.connect(reset_time)
canvas.layersChanged.connect(reset_time)
Now, I wanted to programmatically zoom in, zoom out, enable and disable
layers, etc... but If I give two or more of these commands together, each
command won't wait for the other to finish rendering, therefore I am unable
to measure the time.
For example:
iface.actionZoomFullExtent()
canvas.zoomByFactor(0.5)
Only returns the time for the last zoom to render.
I have tried using time.wait() but that stops the rendering all together.
Thanks,
Alexandre Neto

[Qgis-user] SAGA Next Gen for MacOS
Hello the QGIS community, I wish to use SAGA Terrain Analysis - Lighting Topographic correction in QGIS. I installed the SAGA Next Gen plugin, and it says it requires a manual installation of SAGA 7.2 binaries. I see a folder for SAGA 7.2.0 under SAGA GIS on Source Forge, but there are no binary files for Mac for this version. I ran Topographi Analysis despite the lacking file, it seemed to have run fine but was not able to save the resulting output. I contacted the SAGA help and was instructed to follow the installation instructions here https://sourceforge.net/p/saga-gis/wiki/Compiling%20SAGA%20on%20Mac%20OS%20X/ However, the program failed to compile at the very last step and generated this error.

Re: [Qgis-user] Request for Guidance on Using 'Dissolve' Tool in QGIS with IUCN Data
There is Vector Geometry --> Aggregate algorithm in the Processing Toolbox that can summarize values while dissolving features.
