I have used it in the past, it is excellent.
aduffy•3h ago
QGIS is the shit. I absolutely love it, great for visualizing GeoJSON, GeoTIFF files, open data feeds, etc. My one gripe is that their macOS installers have been out of date for ages now, the best way I've found is to actually install from Conda Forge directly:

> brew install micromamba

> mamba install qgis

It's really crazy the number of open geospatial data feeds that exist out there from NASA, NOAA, and ESA. If you're interested in checking any of this stuff out, I highly encourage following Mark Litwinchik's blog, this guy is a legend and he does most of his work with open tools like QGIS and DuckDB

https://tech.marksblogg.com/

vincnetas•3h ago
brew install --cask qgis
perrygeo•3h ago
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...
aanet•44m ago
Thanks...

Do you absolutely need `mamba` / `conda`??

Can you use `uv` instead to install QGIS? Any experiences to share?

Thanks!!

aerzen•3h ago
My wife uses this a lot. ArcMap used to be de-facto software in her field, but QGis has overtaken that completely. It might not be as polished as ArcMap, it's missing a few guardrails that would prevent you messing up, but it has more features, extensions, better platform support and is free as in beer.

For folks working on QGis: thank you

vincnetas•3h ago
When I have to do anything with geo data i think this is a one of the first tools i reach for. Integrates with lots of formats, storages. Have lots of plugins and scripting functionality. And it's free like in speech.
ageitgey•3h ago
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!

mirchiseth•2h ago
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.
larodi•1h ago
its good for teaching, otherwise it may be super clumsy with large layers and this is unsolvable in the near future. ref. ticket.

even so, we must admit, is still the most comprehensive opensource something to compete with esri.

thirtygeo•57m ago
So weird to see this comment. QGIS powering government GIS groups and used by major geoscience and mining companies.. working with national sized vector and raster data.
markstos•1h ago
I taught myself QGIS for spatial analysis of map data-- coming at it from a coding perspective. It has great Python integration. It's also surprisingly useful as a spreadsheet alternative for certain tasks because it supports a SQL-like interface into CSV data, so you can join CSVs with spatial data or with each other, create views and virtual fields, and so on. Overall, very impressed with the depth, breadth, and ease of use considering how powerful it is.
thirtygeo•59m ago
Arcmap is sooo janky. Looks like a refugee from Win 3.1 era with minor cosmetic updates (although I know the engine received big updates 2010-2020).

If people want QGIS to be pretty, just become a member and sponsor that initiative.

admaiora•52m ago
QGIS is janky? It's quite possibly the smoothest and best running GIS software available today. Most built-in tools run way faster than AG Pro, and once the move to QT6 with 4.0 is complete this october, we'll finally get native builds on M-series Mac as well.

I couldn't even know where to start listing the upsides compared to ESRI offering, fron PostGIS integration all the way to the simplicity of plugins.

showcaseearth•37m ago
>It's quite possibly the smoothest and best running GIS software available today

lol, the bar is not high. It can be both the smoothest and extremely janky at times. Let's be honest with ourselves here. (and I do agree, it's among the best running... but also janky).

4ndrewl•2h ago
I have nothing but good things to say about QGIS.
0cf8612b2e1e•2h ago
Is this on its way to pushing out the incumbent proprietary solution and becoming the standard a la Blender? Or is this more LibreOffice -it’s there, but missing so much functionality/polish that an expert will immediately find blockers vs the status quo?
Qem•2h ago
Probably closer to the first situation. It curb stomped ArcGIS in the geographic information system community. When I started working with GIS at work, expensive ESRI products were default in this market, a la matlab in another field. Most coleages of mine had not heard about QGIS. Now QGIS is ubiquitous. It did to ArcGIS and its countless paid add on modules what scipy/numpy did to matlab.
ingenieroariel•2h ago
The scipy/numpy to matlab is a good example. In my opinion it is on its way but in many places the timing is more like 2010-2013 where a lot of people knew python was the future but universities still used only Matlab.
snypher•2h ago
>It curb stomped ArcGIS in the geographic information system community

Maybe for home or casual use, sure. I use a ~$4500/y Esri license level and it's worth every penny.

Also, plenty of people are still using matlab!

thirtygeo•1h ago
I totally disagree. I switched off this license, and also ALSO saved additional because Spatial Analyst costs extra (all included by default in QGIS)
hyperman1•57m ago
Interesting. I see a lot of people around me using QGIS and all kinds of both free and paid gis tools. I never worked with ArcGIS, except for importing their files, but it seems to be universally loathed around here, even if licensing and money is not the problem. So what are the places where ArcGIS does better?
ZunarJ5•2h ago
It is becoming more and more Blender. Europe relies on it more than Americans, but most GIS specialists use both this and ESRI.
ingenieroariel•2h ago
I think the answer depends on the country: In places where the government uses QGIS it is like Blender. In places where ESRI has a stronghold it is like LibreOffice.
larsiusprime•2h ago
I work in the mass appraisal space, and I use QGIS all the time. The professional alternative is ESRI's ArcGIS.

A lot of shops I know (private and public) will use ArcGIS still, but I'm noticing an increasing number of people (particularly younger researchers/analysts) who are exclusively using QGIS.

QGIS is powerful and full featured, but it is admittedly a bit rusty around the edges, especially when working with very large datasets. If they keep working on fixing some of the sharpest edges I think it will go on to have a good future. Just in the past few years I've noticed significant improvement.

In many ways it feels like Blender -- long ignored and dismissed, but slowly but surely improved over time, and then suddenly became quite a big deal.

thirtygeo•1h ago
If companies that use ESRI cancelled one license a year and instead sponsored qgis development with the money... https://qgis.org/funding/
n8cpdx•2h ago
LibreOffice vs Office 365/Google Drive is probably the more relevant comparison.

I won’t comment on market share, but even if theoretically QGIS totally displaced ArcGIS Pro/ArcMap/ArcGIS on the desktop, the arena of competition has shifted to ArcGIS Online and its competitors. And once you’re in ArcGIS Online, Pro becomes the convenient choice for desktop editing.

LibreOffice could be miles better than Office on desktop, but the competition is lost because Office on desktop is just an accessory for Office 365 (which competes with Google Docs/Drive).

Disclosure: I work at Esri.

duncanfwalker•1h ago
That's an insightful nuance. I've seen you just create divisions in organisations because while it is a really fully featured desktop application, it implies a way of working that doesn't play well with the cloud, which creates barriers between experimenting and production.
mapmeld•19m ago
I work at a university and we do a lot of moving data around, inspecting the files and columns, scripting, etc. so we have everyone use QGIS. Governments and other major consumers have open-ended long-term contracts for whatever Esri products they can think of, so those are solid.

For me the real ongoing question is the role of MapBox, MapLibre, to some extent Google Maps API, and other web-first solutions. It's difficult for Esri to connect with the average web developer or researcher who just wants to start with clickable pins on a map.

dbacar•2h ago
When you mention QGIS, you should also mention GDAL, JTS, udig, geoserver, open stree maps, open scene graph, FWtools etc. Open source GIS has awesome list of projects and people, QGIS being only one of them. It really fascinates me.
Qem•2h ago
I think it did to GIS what Sagemath did to free/open source mathematical software. It integrated everything in a nice package, freeing the users from the burden of dealing with countless disparate packages.
motorest•2h ago
> When you mention QGIS, you should also mention GDAL (...)

GDAL should be front and center. It's the xkcd 2347 of earth observation and geographical information systems

larodi•1h ago
and of course the king - PostGIS

and also that qgis installs 1g+ of all these goodies tied together.

okok3857•21m ago
Fun fact: QGIS was originally written just to view PostGIS tables.
boxerab•2h ago
QGIS is fantastic - it's the only OSS viewer I know of that can consistently and efficiently display multi-GB TIFF images without crashing. It has been a long journey - 20 years to capture ~8% of the geospatial market. ESRI still rules the enterprise, with 40-50% of the market share. More generally, there are so many excellent open source geospatial projects like Geoserver, GDAL, Geonode, Map GL Libre, kepler.gl, Martin, Mapserver, .... but they still have not managed to disrupt ESRI. I think because they are still too fragmented, and still mostly stuck on the desktop, while everything is moving to the cloud.
awesan•2h ago
We are running mapserver in production in the cloud (AWS lambda) to visualize lots of different data using WMS. We're also doing lots of processing using GDAL in the cloud as well. Compared to ESRI it's amazingly cost effective even considering Amazon's high prices.
boxerab•54m ago
nice. If you aren't already familiar, you might be interested in this platform for Dutch geospatial data: https://github.com/PDOK . They use mapserver on the cloud at massive scale, and all of their infra is open.
Tarq0n•12m ago
I do all my GIS work in R, and prefer it to a GUI first approach to be honest.
otter-in-a-suit•2h ago
I adore QGIS. I just built a map (and corresponding GeoPDF file for offline use) for two local wildlife management areas last weekend (and subsequently used them while on them).
kabes•2h ago
Qgis is great on the desktop. On the browser side I find openlayers to be a well thought out gis framework.

A lot of things are evolving though in the gis world. You can now, even in the browser, render huge datasets with geoparquet, geoarrow, wasm and webgl.

jokoon•2h ago
I had geo data to find a new city to move out, with lat lon, population, price, etc

I just used leaflet, it was fine

spatialite is also good enough as a spatial database

unless you are doing complex stuff with GIS data, I don't see the point of using such a large software

rcarmo•1h ago
leaflet is a tile rendering library. You can't edit or massage the data in any way, and most GIS work is not that complex--but it does require handling paths and other things that leaflet cannot really do.
rthnbgrredf•1h ago
If you are in an enterprise setting and you currently evaluate ArcGIS vs QGIS, pick QGIS and thank me later. ArcGIS Enterprise is a piece of software that feels straight out of the 90s and has no native linux binary (can be started with wine). It is expensive as hell and resource hungry.
thirtygeo•1h ago
YES. I made the switch 10 years ago and my professional life improved overnight
atoav•1h ago
My brother is a GIS expert and does this for a living. At his workplace (trans-european electrical project) they use ArcGIS and privately he uses QGIS. He said he'd pick QGIS over ArcGIS every single day.

ArcGIS is very polished, but everything costs extra. QGIS has less polish but is supremely hackable and there are plugins for nearly everything.

Having used QGIS as a non-expert to extract mountain heightmaps from a border region between two datasets from different national bodies and looking up some property borders I can really recommend it. Took me less than an afternoon to get started

showcaseearth•41m ago
+100. There is very little QGIS cannot do as well or better than ArcGIS. For any shortcomings, there are generally other specialized tools that can fill the gaps. It's really just a training issue more than technical one at this point imo.
detourdog•19m ago
What about GRASS?

https://grass.osgeo.org

adeptima•1h ago
QGIS is a gold standard to verify you tools works fine and data is in a correct format ...

if you are a web based first, you have even better options to build and extend

kepler, protomaps, maplibre-gl-js

https://kepler.gl

https://protomaps.com

https://github.com/maplibre/maplibre-gl-js

the rest can be found on great Qiusheng Wu’s (aka @giswqs) Geo/GeoAI tutorials channels and repos

https://www.youtube.com/@giswqs/videos

https://x.com/giswqs

but what really amazed me is how geo spatial support is growing inside of databases recently

https://duckdb.org/docs/stable/core_extensions/spatial/overv...

all mighty postgis https://postgis.net/docs/manual-3.5/postgis_cheatsheet-en.ht...

https://sedona.apache.org/latest/

https://geoparquet.org/releases/v1.0.0/

and many unlocked dataset compare to other industries

https://docs.overturemaps.org/getting-data/duckdb/

https://www.openstreetmap.org/

https://hub.arcgis.com/search

lot great webtools are comming for sure and you still can be 100% of most of your geospatial pipeline

p.s. want to extend the above list with self-hosted tools with minimum or none dependencies on paid APIs, and recommendations are greatly appreciated

throwawayqgis•1h ago
I’ve worked in the GIS space for a while, developed mapping services on the backend and frontend, the whole thing.

And yet I’ve never been able to get into QGIS. I’ve used the ogr libraries, I know that there’s an incredible amount of smart work behind these tools. 100% all due respect to everyone involved.

But I’ve found the ui so daunting that I’ve never been able to use it.

I want to be proven wrong. Are there gentle/great tutorials/guides?

I know this isn’t a “vpn software before tailscale” kind of situation. But, you know?

NoboruWataya•19m ago
It sounds weird but QGIS is one of those projects that I don't use but I love that it exists and wish I had reason to use it more. A bit like Blender.
Fwirt•2m ago
As a hacker, a really fun thing to do with QGIS is locate your local government’s GIS data portal. At least in the US, most data is freely available and can be pulled into QGIS as layers. Fun things like lidar surveys, flood zones, property boundaries. If you’re at all interested in geography and want to explore your locality it can be great fun.
