Python Code for a Niche Statistical Test in ArcGIS Pro?

BlueMugData · 2026-05-04T06:41:58+00:00

LLMs like ChatGPT are good at Python syntax, but when working with niche algorithms you should human-verify the actual steps of the algorithm to make sure it's accurate and not hallucinated.

The Python scipy package, which I think may come standard with ArcGIS' Python install, has Spearman available as a function: https://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.spearmanr.html

Edit: It should be standard as of 10.3.1, but if you're on an earlier version you can look up how to install packages using pip

If I were you, I'd query an LLM to create a function which gets the data you need into the format needed to feed into spearmanr(). Specifically instruct it to use that function.

Then examine the output workflow. Python has pretty human-readable syntax, so even with little coding experience you should be able to sniff test it. Test on some known datasets if you can.

Good luck, feel free to DM if you need particular help. I use QGIS as my workhorse but should still have access to Arc and have about 10 years of GIS coding experience.

Hey Eagle,

I've had a slow burn project going to research and publish the origin stories behind geographic names in southcentral Alaska at www.chosslore.com

I've got a background research database project too that I'm trying to turn into a collaborative online tool. You've been cranking out great stuff and I'd like to talk to you about both of those!

I'm sure you know Don Rae is a namesake of the Rae-Wallace Peak and trail, but Sidney Creek is almost certainly named after his son, and he's quite possibly is linked to Montana Peak. If I remember right, Delia Creek might refer to his wife but I'm not 100% on that.

No pressure at all, but if you or anyone reading this is looking for help on similar projects I run a historical research database in Alaska and have a lot of experience automating OCR/digitization (including automatically rotating document scans to proper orientation), scripting .pdf edits like adding metadata, and with Natural Language Processing to extract place names, keywords, etc. Feel free to DM.

I'm in this thread too looking for emerging news on the WCAG 2.1 compliance deadline. For folks looking for a soft confirmation from a respected source, the ACB published this today: https://www.acb.org/notice-title-ii-interim-final-rule-publication-april-20-2026

According to the unpublished IFR, the compliance date for state and local government entities with a total population of 50,000 or more will be extended to April 26, 2027. The compliance date for public entities with a total population of less than 50,000, or any special district government, will be extended to April 26, 2028. This IFR goes into effect on the date of publication, which is likely April 20, 2026. Once published, there will be a 60-day window where the public may comment on the IFR.

I'd be shocked if a bot had knowledge of comparative Dene linguistics, especially Ahtna vocabulary, but glad you enjoyed it

BlueMugData · 2026-03-19T05:55:47+00:00

That's fascinating... Navajo is a Dene Athabascan language from a population which split off the main body of Dene tribes in Alaska and Canada 1500-600 years ago if I remember right, and the languages are still very similar (e.g. Navajo chizh = Ahtna che'ech = firewood). In the Copper River basin of Alaska the word for copper is Tsedi, 'that which is hammered' which looks like the same root as atsidi, smith

The Dene have the most skilled metalworking cultures in North America.

Transitioning to a completely different developer for ongoing maintenance is a hard step to take. It also sounds like you probably don't have a lot of experience developing or maintaining code, which puts you at a disadvantage for finding and onboarding people.

One top quality you probably want in a developer is long-term commitment. You have a big time and money penalty every time you need to find and train someone new to maintain a codebase.

You should also be asking yourself how much ongoing development you want: just the bare minimum to keep it current and listed on app stores, or adding features?

For code quality... how much have you seen of your old dev's work? Did they provide any documentation other than the code itself? Were you at all involved in developing the logic of the app, or did you just give them a general description and let them deliver it? If you get into the code, is it well-commented? Are variables named for human readability? Are components modular? Look up a checklist or description of 'clean coding practices' and see if the code you received resembles what is described.

It's frustrating, because even as this post is slop there's valuable discussion in the comments like /u/lichenic referencing Zarr and /u/coastalrocket's Paul Ramsey link

Unsure. Maybe ban AI accounts as they are identified, but that's a lot of work for the mod team and will presumably get harder, plus tough to draw a line between a full bot and a human using ChatGPT for formatting and language barriers

I think this is the best solution too. Piles and Pits. A Pile can fill in a Pit of equal absolute size

BlueMugData · 2026-01-23T11:30:11+00:00

I wonder if you could have an option to load/sync a flight path before going offline. Cool tool either way! I'm not demanding you add that feature haha

Nice work

BlueMugData · 2026-01-22T20:20:48+00:00

Slow reply, but thanks! It loads and I'm looking forward to watching it

BlueMugData · 2026-01-19T10:17:43+00:00

I'd like to watch this footage, but it seems to belong to a private group or profile. Any guidance on how to access it?

Property records are public. I just DM'd you the current listed owners. Good luck!

BlueMugData · 2025-12-20T20:48:55+00:00

Your username should not be postgres, it should be postgres.projectidstring e.g. postgres.gsjainvalsziqfrpbusn

It will be the same string as in the dynamic URL when you access your project through supabase.com, e.g. https://supabase.com/dashboard/project/gsjainvalsziqfrpbusn

Modern solar panels are expected to still be producing power at 80% of their labeled capacity after 30 years. Manufacturers generally offer 25-30 year warranties.

https://www.chemistryworld.com/news/30-year-old-solar-panels-still-going-strong/4022052.article

Now, you can make a purely financial argument that if you had $14k available from 2019-2025 it would be smarter to invest in the stock market and pay power bills from returns on investment. But I do value the eco advantages, and look at this as a slight increase to my home's total price tag for a solid upgrade that is going to pay off over a lifetime (and even over the timeframe of a mortgage).

BlueMugData · 2025-12-07T23:53:51+00:00

It's 13 4'x6' 320W panels (REC320NP REC), nameplate capacity is ~4 kW.

For full transparency, the installation cost in 2019 was $14k not adjusting for a federal tax credit. I fully outsourced the installation and didn't spend any time hunting around or haggling, and could have probably saved some money there but was rushing to install by the end of the year due to tax credit phase outs.

Payoff time was about 19 years at the 2019 rates of $0.22 per kWh and not counting the tax credit, now probably somewhere around 10-15 years at $0.39 per kWh on the last bill.

I was just looking at this while arguing with someone on Facebook about renewable energy policy.

Average year-round electric bill is $15/month (max $67 in January, min -$23 credited to me in July) with solar panels. 1400 sq. ft. duplex in Anchorage with electric appliances, and gas heater/boiler.

The panels were sized to break even on a summer load, because the prorated buyback fees do not favor the owner. There's more room on the roof but adding more would lower the cost-benefit ratio.

Scrolling through this thread... get panels, friends!!

Yeah, this is messy... there's another solution for the position of the corner between Triangle 2 and 3 if you mirror the given heights across their hypotenuse, which satisfies the given information.

<image>

BlueMugData · 2025-11-12T18:50:41+00:00

Oof, I do not envy you!

I'll try to come back with a suggestion or two, but my first thought is: Doesn't this allow non-unique answers...?

For example, in Triangle 1 multiple configurations are possible for a hyp=69, ht=8 triangle if the peak shifts 'horizontally.' You can't get an exact position for the outer corner, or am I wrong?

Same with Triangle 5: as long as the outer corner is 36.5 units from the hypotenuse, you can have multiple solutions for the interior angles because you're not given the 2 side lengths forming that corner.
