Persistent blank space in Landsat 8 and 9 LST data

2 Upvotes

I am looking at surface temperature data for an area in the UK. I have downloaded 5 years of summer months and everyone one of images has missing data in the exact same area. The exact location is x: -1.36350 y: 53.26817 and you can see it here Esri | Landsat Explorer. If I look at the QA Pixel file that area returns 21824, which is clear land (no clouds). I don't understand why there is this persistent gap. The AIs tell me it could be linked to Landsat Collection 2 Surface Temperature data gaps due to missing ASTER GED | U.S. Geological Survey

Python I built an open source tool that lets Claude run Google Earth Engine for you

17 Upvotes

I do remote sensing work and got tired of writing the same Google Earth Engine boilerplate for every project, so I built an open source tool that connects Claude to Earth Engine and runs it for you.

You ask in plain language and it does the analysis on Google's servers: a cloud-free satellite image of any area for any year since 1972, vegetation indices, statistics, land cover classification, exports. It picks the right satellite for the year, cloud masks, and harmonizes the bands automatically. For anything custom it can run arbitrary Earth Engine code.

Everything runs locally with your own Earth Engine credentials. Free for research, MIT licensed.

Repo: https://github.com/prahaladuk2208-arch/geeflow

Would this be useful for your workflow, and what would you want it to do that it doesn't yet?

Seeking feedback on OASIS, an AI assisted system I developed to translate climate questions into climate data analyses and geospatial outputs

Post image
5 Upvotes

TLDR:
I built OASIS, an AI-assisted system that translates climate research questions into reproducible climate data analyses and geospatial outputs. It started as a tool to simplify my own thesis workflow, but I am exploring whether this approach could help other researchers and domain experts work with climate and spatial data more efficiently. I would appreciate honest feedback.

Hey everyone,

I recently finished my integrated master's thesis in Crop Science, where I mapped climate risk for olive cultivation across Greece.The results of this research have been submitted to the scientific journal Climate (MDPI), and a preprint version is also available for anyone interested.

Coming from an agricultural background rather than computer science, I had no previous experience writing code or working with large-scale climate datasets. To overcome this, I started using AI to help me build the scripts I needed, both for Google Earth Engine workflows and for processing downloaded Copernicus climate data. However, as the research questions became more complex, I found myself repeatedly adapting the code, changing data paths, modifying parameters and rebuilding similar workflows for each new analysis. This process became very time consuming and shifted my focus away from the scientific questions I wanted to explore.

To solve this frustration, I started building a prototype called OASIS. The goal was simple instead of repeatedly prompting an AI with what I wanted and having to manually validate every single time whether the generated code was actually correct, I wanted a more structured approach where I could describe the analysis in natural language and let the system handle the heavy lifting safely.

The way it works is straightforward. I have already downloaded the climate data needed and the analysis for generating the code is handled either locally through Ollama or via OpenRouter using free models. The system uses rules and validations to correctly handle temporal and spatial parameters for environmental and climate indicators so the AI doesn't have to guess formulas. Each generated analysis is accompanied by the underlying code, allowing users to inspect, validate, and reproduce the workflow if needed.

I also understand that the current implementation is mainly focused on climate data, which may not directly apply to everyone here.

I recently put the technical overview of OASIS on Zenodo (Technical Architecture and Workflow Record) and started realizing that this approach could be useful beyond my own research, especially for domain experts, scientists, and consultants who need climate insights but may not have the technical background to build these workflows themselves. Managing large climate datasets and setting up the required processing environment can be a significant barrier, especially for those who are not familiar with coding or data infrastructure.

My long-term vision is to evolve OASIS into a more scalable platform, potentially through a cloud-based infrastructure, making climate and geospatial analysis more accessible to a wider audience, while simultaneously ensuring it is faster and much easier to use for those who are already actively working with these workflows.

Before taking this further, I would really appreciate some honest and critical feedback from this community.

  1. Which groups do you think would benefit most from this approach? For example, researchers, consultants, decision-makers, or other domain experts who may not have a strong coding background or simply want to speed up their workflows?
  2. If you already work with large climate or environmental datasets, would you personally use a system like this? Would having cloud access to ready-to-use datasets and analysis workflows be valuable, instead of downloading and managing everything locally?

If anyone is interested in the research background behind the use case, I would also be happy to share the preprint of the climate risk assessment study.

Thank you for any feedback, positive or critical!

Processing 2023 Sentinel-3 OLCI data into a zoomable pseudo-daily global map. Is this useful, or just a fun hobby?

4 Upvotes

I’ve been working on a hobby project processing Sentinel-3 OLCI and GFS data and wanted to get some feedback from the community. I’m mostly doing this for the love of the visuals and the challenge of data compression and GPU shader optimization but I’m curious if this has actual, practical utility for anyone else.

Currently processing all Sentinel-3 OLCI data for 2023 across 9 color channels (Oa03-Oa08, Oa10-Oa11, and Oa17). Atmospheric correcting using Eric Bruneton's precomputed scattering model, deglinting and then removing clouds in a sliding window using an algorithm from the paper "Global clear sky near-surface imagery from multiple satellite daily imagery time series" extended with more color channels, Gaussian weighting of images around a central day and smoothly fading weights to zero at swath edges. I've got SLSTR data too, but don't know if / how to include it.

Ultimately I'll create 12 multispectral JPEG XL tile pyramids for web use. There's a really fast small custom Wasm and WebGL -based decoder that makes them already work in browsers. They're not just crossfaded, there's extra daily information stored tracking how close each pixel should look like to either endpoint of a month, so it captures changes in daily resolution (as well as it can after cloud removal with some weighted medians over a multi-week sliding window).

This is intended to complement weather data in a proof of concept web app already at openpla.net

I could extend it from 2023 a bit more to the past, and then to the present and future if this is useful for something. For pretty pictures and a portfolio, one year might be enough. I could also potentially fuse Sentinel-2 data for some areas of interest. Taking only high frequencies from it should make the BRDF stripes disappear, which is why I originally started the whole project.

Now that I know the names, bounds and times of all Sentinel 3 granules, and their deltas from clear sky, it could also show very quickly what granules cover some area and time, with grayscale thumbnails showing only cloud cover to judge their utility. Or identify the Sentinel 2 tiles like "T35VLG" that cover some spot.

Any ideas or comments would be really welcome. Does this sound useful, or would sound with changes?

Normalization of data in deep learning

4 Upvotes

Hey everyone,

I have recently started my DL journey after attending a course in the university.

For my project, I have decided to do a binary segmentation using satellite imageries with 4 channels (Red, Green, Blue and Near Infrared) using Unet. I have divided the data to training, test and validation dataset. I would like to know what is the best strategy to normalize my dataset.

Someone told me to calculate minimum and maximum values or mean and SD across all 4 channels in **Training dataset only and use these values to normalize the entire training, test and validation dataset.** My current approach is normalizing individual images with its min and max values for all dataset. Is thing wrong approach?

Thanks for any feedbacks!

Transitioning from MRI

3 Upvotes

Hey everyone, I am an MRI physicist who has always enjoyed climate physics, earth observation, oceanography, satellites etc and I've grown a bit bored with MRI for the time being. I have a PhD in MRI physics and I am currently doing a post doc as well.

As a next career step, I'd like to apply my imaging expertise in a different field...in my research about where I could fit, I came across things like remote sensing or cal/val or SAR or RF signal processing but I worry about breaking into this field as someone with years of experience applying imaging to lungs instead of working with the type of equipment and topics that would be relevant to this field.

I'm currently based in the UK but I am a Canadian citizen. Any advice for me? Has anybody seen in their workplaces people who have transitioned into this field and if so what are ways I could do this?

interested to hear your thoughts! industry capability development for Earth Observation

10 Upvotes

HI ive gone out on my own and passionate on Earth Observation + Education. I see a rather frustrating trend in the industry today - in trying to address it, I also do not want to waste time on Earth Observation training content that goes under utilized, spend my time in the real problems

Graduates aren't entering fast enough to keep pace with how quickly the tech is moving. Meanwhile, people are arriving from adjacent fields, never formally trained in GIS/Remote Sensing, but doing real geospatial work every single day. Organisations are asking everyone to do more with less.
So how do these people get trained? Two options, really. Generic online courses that don't go deep enough, or training that only teaches one specific tool, taught behind sales incentives for that tool.
Either way not giving the industry the technology agnostic, thought driven capability development it deserves.

When someone's only training is tool specific, they're locking themselves into a platform. They start pressing buttons because they can, not because they understand why. We get vendor lock in as it's too hard to re-train on something else, and we get users who can operate software but not the reasonings we were taught in university behind it.

I'm not saying industry training should replace university training. University trained practitioners stay vital. What I'm saying is there's a need RIGHT NOW that isn't being met: true capability development. The transferable kind. Technology agnostic, faster paced, and built to evolve, without the sales incentives that bend tool specific training out of shape.
We need a space where everyone's learning different tools for the same job - not just tool specific communities as we see now - so we can grow and change and adapt in the industry known for change.

So I'm trying to build it. The problem I am facing however is the platform and engagement - coursera and other training platforms seem quite siloed - i want something more engaging with students. SKOOL has been the closest so far - good balance between user engagement but also course structure. The engagement i see here on Reddit is absolutely amazing but its not really a platform where someone could engage and retain focus along a course? So my question - is it valuable if i push out free content free community but then only white label to departments or businesses my polished course content? I see the need out there in Earth Observation but lacking means to address an audience to get the knowledge out there, effectively any suggestions here would be appreciated. Just a solo consultant trying to get EO out to a broader audience

Novice prospector with 300+ ha gold claim in Zvishavane, Zimbabwe — can remote sensing help me find oxide zones or gold signatures without expensive equipment?

Post image
16 Upvotes

Hi all,

I hold registered mining rights to a greenstone belt property of just over 300 hectares in the Zvishavane area of Zimbabwe (Midlands province, part of the Mberengwa Greenstone Belt). I’ve done what ground exploration I can — walking the claim, identifying outcrop, taking photos and rock samples — but I have zero budget for trenching, IP/magnetic geophysics, or commercial remote sensing services.

What I’m hoping to learn from this community:
1. Can red/iron oxide zones (gossans) actually be picked out reliably from free or low-cost satellite imagery (Sentinel-2, Landsat, etc.)? If so, which band combinations or indices would you suggest for someone just starting out?
2. Is there any way to get a rough read on alteration zones or possible gold-bearing structures from satellite data alone, without ground-truthed spectral libraries?
3. Are there any free or open tools/platforms you’d recommend for a complete beginner trying to do this on a shoestring?
I’m not expecting satellite imagery to “find gold” — I understand its limits — but if it can help me prioritize where to focus my limited ground sampling, that would be huge.

For reference, here are my registered claim boundary coordinates (UTM, Zone 36S):
Claim E:
• A: 813082.17 E, 7769641.64 N
• B: 814137.58 E, 7768185.70 N
• C: 813510.24 E, 7767513.95 N
• D: 812581.76 E, 7768995.22 N
Claim F:
• A: 812581.00 E, 7768994.91 N
• B: 812569.91 E, 7768500.57 N
• C: 812611.31 E, 7767981.32 N
• D: 812800.13 E, 7767980.13 N
• E: 812779.76 E, 7768501.56 N
• F: 812697.72 E, 7768626.03 N
• G: 813509.91 E, 7767612.63 N
• H: 812750.86 E, 7766617.60
• I: 811911.11 E, 7768243.47 N

Happy to share imagery too if anyone’s willing to take a look.
Appreciate any guidance, even pointing me toward beginner resources.

In my first picture, the final prediction output after applying deep learning to satellite imagery shows a blocky pattern. How can I solve this? Can it be solved internally without using any filters or windows?
Note: I created patches during training
and used the second picture for the deep learning process.
