I have an old colleague (a retired geologist and remote sensing guy) who is desperate for qgis help. Qgis is unable to find GRASS or PCraster, maybe a dll problem. He's working with his wife on a Sicilian archaeology project. DM me if willing to help. #QGIS #GISCHAT

Installing QGIS3 using Macports to get GRASS and PCRaster tools to function - install fail due to missing XCode installation?
I am attempting to re-install QGIS3 on my laptop running Mac OS Tahoe 26.5.2 with the goal of getting GRASS and PCRaster tools to function again (they used to...what happened I don't know?). I am experiencing the following error, after which the QGIS3 install fails: * Error: Port py314-pyqt5 requires a full Xcode installation, which was not found on your system. * Error: You can install Xcode from the Mac App Store or https://developer.apple.com/xcode/ * Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_python_py-pyqt5/py314-pyqt5/main.log for details. * Error: Follow https://guide.macports.org/#project.tickets if you believe there is a bug. * Error: Processing of port qgis3 failed Thus far I have run the following commands with no issue: * sudo port selfupdate * sudo port upgrade outdated * sudo port install saga * sudo port install py311-pysaga QGIS3 install ultimately fails after I run: * sudo port install qgis3 +grass I have Xcode installed on my machine in the default location. Does the Xcode location need to be changed in order for the QGIS install to proceed? If so, can anyone point me in the right direction? I am not technical (pretty obvious) and am stumbling through all of this command line stuff - just need to get my QGIS back and functional for the earthworks I design and implement. Thank you in advance for any help!

What is the best method for catchment delination?
I am trying to delineate a catchment of a particular water basin, and I am getting unexpected results. I am not sure what the reason is behind it, and I have followed so many tutorials that now I am more confused about which one is better. So, as far as I have learned, there are three major tools that you can use to delineate catchment. * PCRaster * SAGA next gen * GRASS Even before I figure out what the issue is with my process. Can anyone tell me which one is better and which one is more reliable to use? My AOI is a Lake in the Ladakh region of India, and I have used CartoDEM, CopernicusDEM and ALOS.
