Qgis is powerful and free but it’s slow, has the steepest learning curve and gets in your way. I am happy it exists but it’s not great.

If using an Apple silicon Mac, it will be way faster after if you install (compile from source) via Mac ports.

As far as learning curve, I agree, but I have had a lot of luck as a beginner asking ChatGPT how to use qgis to do specific tasks and it walked me through them in detail correctly.

QGIS is a very useful tool that I often rely on for quick exploration of datasets in my work. But dear god the UI is in desperate need of a huge overhaul by someone who knows what they are doing. Massed rows of toolbars with tiny icons, lots of unintuitive behaviour, and a few weird quirks. It's a very powerful tool, but so much of its utility is completely inaccessible without tutorials and videos to explain it.

Been using QGIS for about 6 years now for doing manual data analysis, as well as GDAL and Spatialite in C++ for creating/saving datasets and geopandas, Shapely, pyproj, etc for automated analysis. QGIS is an odd duck. Part of the complexity of using it is the fundamental complexity of GIS software. There’s way more background info that I didn’t know (what do you mean a latitude and longitude doesn’t mean anything wit…

Hard agree on it being odd in both GIS ways and QGIS ways. I just started a new job that pays for ArcGIS Pro and it’s wild how something that seemed intuitive to find on QGIS is buried under menus on Arc Pro, but conversely I’ve definitely seen things that I’m like “that was almost too easy why doesn’t QGIS have this”. And then you have the oddities of GIS

brew install --cask qgis

Unfortunately the homebrew cask is still Intel-only so it requires Rosetta, whereas the conda/mamba version has an osx-arm64 build. There are other workarounds discussed here: https://github.com/qgis/QGIS/issues/46299 and here https://geo.malagis.com/native-qgis-on-apple-silicon-solutio...

Strongly recommend apple silicon Mac (if using a Mac) and the Mac ports path. I have an m4 MacBook Pro and the Rosetta powered binary was almost unusable. Mac ports wasn’t too hard for me to figure out though the install (mostly compiling) took several hours. I have had no issues with coexistence of Mac ports and homebrew. Don’t attempt this is you are using beta builds of tahoe - Mac ports isn’t released for Tahoe yet.

Ah QGIS. Love working with it (it got me through university + 3 years of being in the planning industry w/o touching Esri)! hated managing it on the Mac admin side (no ARM native build and more importantly no notarized builds). I do hear v4 might fix both issues so I’m looking forward to that next month.

I'm acutely aware of that. The folks who hired me didn't realize I was also a hacker. I did my due diligence as well, and this was more 10.3 . And yes, it was terrible. I know that FEMA and EPA both are running their public portals as 10.8 , which is really bad. There's usually between 8-12 critical (cvss 3.0 9 or greater) per version bump. Fuck if I know how federal acquisitions even allow this, but yeahhh. Also, on…

This is horrible!

It's sadly the norm for monopolistic industry-specific software. You see the same lack of due diligence in SCADA software and the like.

QGIS is great. It's a slightly janky version of ArcMap, but ArcMap has always been janky anyway, so it doesn't matter for most things. And QGIS is super extensible. There have been so many random times that QGIS has helped me out over the years. Thanks to everyone who has contributed to it!

Do you work in GIS field and it is useful? I am trying to see how a GIS tool will help a typical audience here that may be a little interested in maps + data.

I used to work at an ISP based in the UK. They also put fibre in the ground. Their entire "design" tool was basically a huge QGIS python plug-in.

It is incredible the flexibility QGIS gives you. By paying a couple of developers the company probably saved millions in software.

I come from the ArcView 3 / ArcInfo days. I still maintain a non professional home license which is nice, however they killed off ArcMap for non-enterprise and I just cant for the life of me get into Arc Pro or QGis. Old dog, no new tricks for me I guess.

Geopandas and QGIS are my go to. QGIS for basic work, automate with Geopandas. It makes the work a lot of fun!

Any tips on smoothing the transition between the two that mean work isn't duplicated?

I work with QGIS, but until recently I’ve only skated over the surface. In the last year or so I’ve found LLMs increasingly useful as a companion to help me code automation scripts or just to ask “how can I do this?” questions. QGIS is deep and powerful but that power can be hard to access. LLMs make it a lot easier.

My wife says something similar. She's used QGIS for years, but never as the main part of her job (she's an archaeologist) and has said ChatGPT has opened up loads of stuff that would've taken her ages to work out before. It even got her using Python.

I do all my GIS work in R, and prefer it to a GUI first approach to be honest.

What R modules do you use for that?

There are quite a few. https://guides.library.columbia.edu/geotools/R I mostly used sf at uni and also preferd it to QGIS in most scenarios. Far from a pro user though.
