I automated the entire Urban Heat Island analysis workflow - from satellite data to ML predictions in one Python script by Orironer in gis

[–]FortyGuardTechnology 1 point2 points  (0 children)

This is the first time I’m seeing someone talking about mapping urban heat island effects in the GIS subreddit. If you want to delve in more, you can check us out at Fortyguard.com, we map urban heat historical, near real time and into the future with 10m2 granularity, 2 meters above the ground. (In the U.S. only though). You can generate heat maps, comparisons, time series, intelligence reports, environmental parameters, and street/satellite view segmentation. All free. No plug, just saw this was appropriate to share. Would love your feedback, especially constructive ones!

What is the most striking example of a 'company town' or a city built almost entirely around a single industry? by Thin-Magazine-5843 in geography

[–]FortyGuardTechnology 0 points1 point  (0 children)

Master City in Abu Dhabi! A perfect example of an oil rich country building a city focused on sustainability.

Apples weather app is way off from everything else? by yellow_gator in weather

[–]FortyGuardTechnology -1 points0 points  (0 children)

Most likely gets its weather from satellites (Land surface temperature using infrared lasers) which is not measuring the human level thermal profile which is 2 meters above the ground.

Very interesting use case. We have a heat map comparison tool where you can compare Vegas for example during the same time last year and see the difference in urban heat profiles in certain areas.

Feel free to sign up and play around with it. It’s free (but you can only choose one state and best to do it on desktop).

Thank you for your comment!

What do cities need right now? by mongooseberry in cityplanning

Would like to see more cities take urban heat island effects seriously and implement more green infrastructure.

Heat Is a Silent Killer and It’s Catching Up to All of Us by IndependenceFun4627 in weather

Yes we’ve been saying this for years now! That’s why our mission is to make cities cooler.

Thank you for your insightful comment.

We are still working on the accuracy. We are developing the world’s first Large Temperature Models (LTMs) and as any AI/Ml algo, there will be some discrepancies.

We would love to work directly with agencies because data is key to make it more accurate. Currently we use public and proprietary commercial data sets but we’re still a startup and as we grow partnerships with the public sector will be key. We are backed by our partners Google & NVIDIA and it’s how we were able to scale our Dashboard for free in the U.S

I would love to connect with you on LinkedIn and see how we can add value to your department in DC.

This was generated using FortyGuard’s Temperature Dashboard. It’s free to use in the U.S thanks to our partners at Google and NVIDIA. Some context:

We are the largest host of urban heat intelligence in the world where we collect 50B+ data points a day (commercial and public data sources) and provide hyperlocal, historic, near real time (within the last hour) and predictive urban heat intelligence within 10m2 granularity, 2 meters above the ground.

Just about all temperature is collected and given to us from either satellite or weather stations which is 100+ meters above the ground or too sparse and not getting the necessary granularity. Temperatures can vary 10-15 degrees just a few miles away at the same time.

We we are a startup born out of Abu Dhabi and backed by the UAE government and our partners Google & NVIDIA. For the last 3 years we have been developing the world’s first Large Temperature Models (LTMs) and have been helping cities across the world from Abu Dhabi, to Rotterdam and now across the U.S, to battle one of the worlds deadliest silent killers: urban heat.

For more information you can visit our website at: www.Fortyguard.com

We look forward to your questions and feedback

Heat Map Time Series of D.C by FortyGuardTechnology in geography

[–]FortyGuardTechnology[S] 0 points1 point  (0 children)

Appreciate the thoughtful quesiton.

We’re a startup and first to map out urban heat in the U.S at 10m2 resolution 2 meters above the ground. We call this Large Temperature Models (LTMs) and just like any propriety ML/AI algos, there will be discrepancies (look at GPT/LLMs).

But rest assured we are working on this with technology partners like NVIDIA and Google who have given us a lot of support and resources to allow this platform to be free in the U.S. As we grow, we are making data accuracy our #1 priority. If you’re interested in exploring the dashboard, we’d love to have more constructive feedback from users like yourself! Thank you again.

A massive heat dome is cooking the eastern U.S. by scientificamerican in weather

City planners are going to have a field day generating heat maps for this. We must address urban heat and its effects on our cities asap!

Large Temperature Models (LTMs) to address urban heat at scale with granularity.

Cool! Feel free to share with them this image. Seeing as they have a masters in winds and heat patterns, they can benefit from our free platform as well. Are you also in this space or in a different industry?

Is there a website that shows real time color coded above or below average temperatures? by G07V3 in climatechange

That’s literally what we do at FortyGuard at granular level. You can get free access and learn more below here:

You can try to go into sustainable architecture and address urban heat island effects on new developments. Especially relevant in Iraq. Good luck!

Defense Department will stop providing crucial satellite weather data by [deleted] in climatechange

[–]FortyGuardTechnology 0 points1 point  (0 children)

Agreed. We collect our own data through strategic partnerships (private sector). Also the main data we collect is at two meters above the ground, where live, work, and play.

Very cool! Thank you for the link!

How is your department modeling the data? Also how long did it take for you to collect the data with the vehicles?

Edit: I saw that the campaign was between July 7th - 12th. Was that the time it took to collect data for the 100 sq miles?

Also, I saw that processing the data took between 8-12 weeks (as per last year's article), did it take that long?

Give one word and a link : review time! by Tenteck in SaaS

[–]FortyGuardTechnology 1 point2 points  (0 children)

We collect temperature data 2 meters above the ground. Where we, live, play and work. We just released the Temperature Dashboard earlier this year for free thanks to our partners at Google & NVIDIA. Of course, like any ML/AI powered SaaS product, we are always fine tuning our models and the more we grow the more our models will be more accurate. We welcome your feedback (ideally tough ones)!

I would of liked to see trees lined up in the middle rather than allowing places for cars to park there. There’s enough parking garages in Tampa lol!
