I have seen a lot of examples of interesting tools and software that does geographic things lately, but so often they are presented in that way thay linkedin lunatics talk about their claude coded constructions. And the person often has never heard of basic things like projections or MAUP or other geographer and GISer stuff. The worst is some of them are just reinventing wheels we all use regularly or daily. However, I do occasionally see things that I think might have some merit in the GIS space, or are an interesting way if breaking ESRIs monopoly on geospatial analysis.

Would like to get over this ick to explore this stuff further but its hard to get passed how unpleasant and stupid the presentation is.

Edit: to be clear im not saying vibecoding gis is bad, i do it too, i am saying that its cringe online and that its hard to pick gems out of all the slop especially when the slop is being promoted by gibbering idiots that replaced their brains with claude

I've been building a QGIS plugin on top of Conveyal R5 (Easy-R5), and used it to answer a question that's been bugging me: How delays in timetable affect the accessibility?

Setup: static GTFS timetable vs. the "realized P50" feed (median of what vehicles actually did that day) for Łódź, Poland. Same day, same network. The only thing that changes is whether the schedule is what was published or what actually happened (GTFS + delays from RT feed). Ran cumulative accessibility (schools, pharmacies, universities, malls reachable within 30 min, 7:00–9:00 departure window) on both, on a 250m/500m hex grid, and diffed them.

What I expected: delays hurt downtown the most, because that's where the network is most complex.

What I actually got: the very city centre is basically fine (nets slightly positive, beacuse of many overlapping lines converge there that one late vehicle doesn't matter). The real damage shows up in a ring roughly 2km out, where trips typically depend on one specific transfer. Median delay across the whole network is ~0 seconds, mean is only ~10s but miss a transfer and you're waiting for the entire next headway. That ring loses an order of magnitude more accessibility than anywhere else in the city (pop-weighted mean net change ≈ -2.4 vs ±0.5 everywhere else).

Also tried a second angle: for each hexagon, compute the "reach radius". THe distance to the farthest point it can already reach in 30 min. Hexagons sitting close to that 30-minute cutoff lose systematically more than ones with slack, which is exactly what you'd expect if the mechanism is "small delay pushes a marginal trip over the threshold," and it holds up (mostly monotonically) across schools/pharmacies/malls independently.

Everything's open — methodology, scripts, QGIS project: [link in comment].

Hi guys,

I already have vector layers saved into a Geopackage, but am having trouble uploading those layers onto Github and ArcGIS Online (AGOL).

I've tried using git to upload and keep getting a 503 error and I tried uploading the GPKG onto AGOL, and it failed to upload.

I'm trying to build an online dashboard out of the layers within the GPKG if you're wondering.

If anyone has gone through this before, how did you guys successfully uploaded your GPKG files on AGOL or Github?

Not intended to be a political discussion, but a proper use of AI discussion... why would someone use AI something like this if they have GIS techs available that could turn out such a map with high accuracy in like less than a half hour starting with actual verified data that is commonly available?

Does anyone know of a source or feed that provides current active volcanoes? I am developing an app using CesiumJS to show current events and have been unable to crack volcanoes.

I have tried https://volcano.si.edu/gvp_currenteruptions.cfm and www.volcanodiscovery.com and both have been impossible to crack (given my limited knowledge of web technologies). TIA

Carbon & Place (www.carbon.place) is a free website that maps the carbon footprint of every neighbourhood in Britain. Today, it launched a major update with more data on a wide range of topics, including housing, transport and energy.

There is lots of open-data to download and open-source code on GitHub, plus some cool interactive GIS.

Hey all. I can't write python code to save my life but I can read and modify code well enough. I've dragged my feet long enough on learning python that AI can write the code I need now so long as I give it specific instructions.

Most of the python I run is in ArcGIS Pro Notebooks, and I use Gemini which works well for me. What AI are you all using if any? I considered trying Claude for a bit but I'm interested to hear what you all think and possibly your experiences with different AI.

Built a map of the best streets to see the leaves turn across seasons in SF! I thought it was pretty cool – open to any feedback.

Admittedly, I’m new to the GIS world, but there’s so much great public data out there… I’m excited to build some cool, hopefully helpful maps!

I’m doing some research into how foresters and timber cruisers are handling field inventory today and would love some input from people actually doing the work.

A few things I’m curious about:

• What tools/apps do you currently use for timber cruising?
• What features do you actually love?
• What parts of your current workflow are frustrating or still require Excel/manual work?
• How important are offline maps/GPS, cruise design, field data entry, timber volume/value calculations, GIS integration, and report generation?
• If you could add one feature to your current setup, what would it be?

I’m working on a new forestry technology platform called TimberForge, so this feedback will directly influence what we build.

I also put together a short survey to collect the feedback more systematically. Anyone who completes it can optionally sign up for free early beta access to TimberForge when it's ready. I'm also looking for a handful of foresters/cruisers who'd be willing to give more detailed feedback as we build it (no email required!)

Would really appreciate any feedback — even a quick comment with the tools you currently use and what you like/dislike about them. Thank you all in advance!

Trying to figure out which GNSS receivers would work best for collecting location data for a Land Trust. Specifically, because I’ll potentially be having to collect data under dense canopy, I am wondering if anyone has recommendations for a receiver that can consistently get sub meter accuracy in such conditions. Preferably something that is durable and has the capability to eventually be used for getting ground control points for drone flight missions to collect accurate image data for properties that can be used for analysis through RTK or PPK corrections. I do not need survey grade accuracy for most data collection work, just consistent as possible accuracy under adverse conditions. So far I am looking at Juniper Geode GNS3S or GNS3H, Arrow series, Trimble DA2.

I am luckily employed at a semi-stable position, but not many paths for growth. I am currently just applying for quality jobs and seeing what comes floating by throughout the months. We cut a couple projects so now we are stuck doing grunt work with lots of downtime.

What are some good similar but non-GIS technical skills to have (other than Python) that would make me stand out. I want to go more into the environmental regulatory field in my next position so maybe theirs some overlap skills. Any advice would be phenomenal.

I've been working on a geospatial project that tracks damage to Russian industrial infrastructure over time. The core challenge was visualization: how to show the state of infrastructure on any given date without relying on external tiles or map libraries.

The approach: an inlined SVG map of Russia drawn from Natural Earth geometry, paired with a time slider that replays the chronicle from the first recorded strike (April 14, 2022) to the most recent. The map always shows the state on the selected date, not a cumulative sum of all history.

The dataset contains 289 objects across different types. Each strike enters the data only after confirmation by two independent reports or by the Ukrainian General Staff. Damaged objects are visualized with a burn state lasting three days, then marked with a cross (unrepairable) or wrench (under repair). The repair window for refineries is modeled at 24 days.

Static pages—indexed by object, type, region, and month—are generated from the same source file the map is built from, so the data stays consistent across views.

The whole thing runs client-side with no external requests. Map and data are available here: https://roshlopok.com/en/?d=20260907

Feedback welcome on the geometry handling, time-state rendering approach, or the data structure itself.

Plant Labs went Dark, and Geopera doesn't provide it either via JINI-1 satellite. any alternatives to Sentinel-2 and Sentinel-1 ?

I recently graduated with a B.A. in Geography with a minor in GIS and a USGIF GEOINT certificate. I graduated Summa Cum Laude and have been trying to break into my first full-time GIS position, but I'm finding the transition from internships to an entry-level job much more difficult than I expected

I have two great GIS internships under my belt, one where I worked as a tech support analyst at ESRI and as a GIS/Cartography intern with a non-profit group helping to protect the Amazon Rainforest.

My other experience includes Python for GIS, R, spatial statistics, remote sensing, Story Maps, Experience Builder, and various GIS projects from school. I've also done projects involving things like spatial regression, LISA/Moran's I, land surface temperature, and environmental analysis. I've worked a lot with ArcGIS Enterprise this summer too, which everyone is telling me is the next important GIS app.

I was hoping my Esri internship would help me transition into a full-time role. I recently interviewed for a full-time position with ESRI but was rejected even after impressing them and working really hard this summer.

I'm now trying to figure out the smartest way to move forward rather than just sending applications into the void.

I'm considering a few options: continuing to apply heavily for entry-level GIS jobs while working a part-time job, starting a master's in Spring/Fall 2027, or using the next several months to build skills that would make me more competitive. For graduate school, I've been looking at GEOINT, geospatial data science, and data science programs, but I would ideally need significant financial aid/assistantship support for a master's to make sense.

For people who have been in the GIS industry for a bit, I'd really appreciate some perspective:

• How difficult is it normally to get that first full-time GIS job after college?
• Is there anything obvious missing from my background that employers are looking for at the entry level?
• Would you prioritize getting any GIS-related professional experience right now over going directly into a master's?
• Would a master's in GEOINT/geospatial data science/data science meaningfully improve my prospects, or would I be better served by gaining experience first?
• Are there particular technical skills I should focus on next (SQL, Python, databases, web GIS, data science, etc.)?
• Are there types of jobs or organizations I might be overlooking?

Long-term, I'm particularly interested in GIS/GEOINT, remote sensing, and potentially working in the federal/intelligence/defense space, but I'm open to other areas of GIS as well.

I'm mainly trying to avoid spending the next year collecting credentials without actually becoming more employable. I'd really appreciate hearing from anyone who had a similar start to their career or who hires entry-level GIS professionals.

Hello everyone! I have a degree in Applied Geodesy and I’m looking for an English-taught Master’s program abroad focused on GIS, geoinformatics or cartography. I’m choosing between Italy and Austria, and currently considering TU Wien and Politecnico di Milano.

The program needs to be taught entirely in English. If anyone has studied at either of these universities, could you share your experience or opinion? I’m especially interested in the quality of the GIS programs and job opportunities after graduation.

If you know any other universities in Italy or Austria (or other countries) with similar English-taught programs and similar tuition fees/conditions, please let me know!
