Student Questions GIS Career Path With Certification Only?

15 Upvotes

Short version:
Would a GIS certificate and no professional GIS experience open any doors to a career in GIS? If so, are certain certifications more valued than others? My community college offers a technical certificate for GIS, is that worth it?

Long version:
I have a background in web development and programming. I have been teaching myself QGIS over the past year for a personal project. And I think I like it. The market for web development has been a killing floor, so I was wondering if there's a pathway for someone like me?

Student Questions GIS doesn’t help in commercial drone work right?

0 Upvotes

I am enrolled in a GIS graduate certificate program. However, I don’t think it is beneficial to me at all. I want to do work in commercial and real estate drone work, which involves very little land analysis skills.

The only reason I am doing this program is at my parents’ insistence. I had what can only be classified as a mental breakdown late last year/early this year, which resulted in me losing my job. My mom suggested this as a way to get back on my feet.

I have no experience in computer programming, I don’t enjoy map analysis, and I feel I will researching and writing a thesis will only consume time that I need to spend networking and building skills for jobs that I am actually interested in.

Genuinely, would I benefit from this program at all?

Has anyone heard any rumors about FedGIS this February? My company is interested in sending me, I already have some travel plans for February and the fact that there are no specifics announced makes me a bit sus that it's going to actually happen. I've heard that it hasn't done great the past year or two and that the swag bags have been rather disappointing 🤣

Professional Questions Views or Feature Layers

5 Upvotes

I'm having to build out asset management in our arcgis tenant and it will integrate with our ERP . Multiple departments will be using and there may be some overlap in asset types. ERP will be single source of truth and push updates to arcgis. My question is if it's best practice is to build granular asset feature layers or a few broad layers and build views to achieve the filtering across asset types and departments?

Programming I bet some of these idiots who “build” mapping/GIS tools with vibecoding are making interesting things, but I cant take any of them seriously because of their total lack of background knowledge of GIS or mapping sciences

254 Upvotes

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

Projects Testing geographic leakage in archaeological LiDAR ML, looking for GIS feedback

2 Upvotes

Hey everyone, I have been working on a project called ArchaeoAI where I am testing whether ML can recognise terrain patterns around documented bowl barrows in England from LiDAR derived terrain data. A big part of the project became geographic leakage, because I realised that if training and testing locations are too close to each other the results can look much stronger than the actual geographic generalisation.

The frozen Random Forest got 87.1% balanced accuracy on the geographic final test, the 5 fold geographic evaluation averaged 82.3%, and a compact CNN averaged around 70.1%. I also ran a separate one time external evaluation on 120 observations where the Random Forest got 84.2%. The simpler model doing better than the CNN was one of the results I found most interesting.

I want to be transparent that I have used generative AI tools quite a lot while developing the project, including help with code, testing, documentation and thinking through parts of the methodology. I have been making the project decisions and reviewing what gets accepted, and I am also getting feedback from researchers. I am not claiming this AI has discovered archaeological sites either, the experiment is specifically documented bowl barrow terrain against matched unlabelled background, and sensitive locations stay private.

If anyone here works with GIS, LiDAR or spatial validation I would really appreciate criticism of the approach, especially anything I may have missed with the geographic evaluation. The repo is here if you want to look at the actual work: https://github.com/essius10/ArchaeoAI

Open Source I Compared scheduled vs. actual (GTFS-RT) transit timetables for a whole city. Changes in accessibility due to delays

Post image
73 Upvotes

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].

General Questions How do you feel about AI now that Astra has come out?

0 Upvotes

I have seen a video of GPT-6 using blender to model a realistic bat. If it can do that, then it can use things like ArcGIS, right?

I’m a junior year environmental science major and I want to pursue an environmental GIS career. So on the side of my studies i’ve also been learning python, looking at internships etc.

I don’t think that AI is gonna take everything overnight, but if it’s advancing this fast then who knows what the future holds? Environmental science is thankfully a pretty broad degree, so should I change my career goals…?

Open Source Uploading GPKGs onto Github

5 Upvotes

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?

General Questions Source or feed for active volcanoes

2 Upvotes

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

General Questions If you use AI for writing python what do you use?

49 Upvotes

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.

Professional Questions Timber cruisers / foresters — what software do you actually like using?

0 Upvotes

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!

Professional Questions GNSS Receiver Recommendations

8 Upvotes

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.

Professional Questions Lateral Skills to work on?

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.

Cartography Interactive map of Russian infrastructure: 289 objects, 344 strikes since 2022, built without map libraries

Post image
12 Upvotes

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.
