OpenStreetMap data really is a godsend for such OSINT purposes. Works much better in populated areas too, with more features like roads, shops, electric lines that can be used to search.

Claude / Gemini + OSM Turbo is a crazy you can do natural language queries like "find me a bus stop in germany that's surrounded by more than 5 three story buildings"

Earlier quoted context omitted.

If you know the camera make and model, you might be able to get lens parameters and get better estimates of real world geometry from the image

yea thank u, that's another part, but mainly it would hard although knowing that, because you need to know elevation of the drone or the camera, which is also extremely difficult (I already mentioned that in the blog)

The camera make and model wouldn't tell you the lens parameters. The EXIF would, but that was already covered in the triplet.

Excellent read, I loved it. Incidentally, the image seems to be the one the resort uses on their website! https://oanresort.wixsite.com/chuuk

thanks, and yea, it should be solved easily by passing the img to google lens, the website is the first result, but I found a fun opportunity to solve it in different way

I meant the blog itself, the writeup, the steps and the walkthrough all by hand , the final code u see is llm refined, of course, I wont publish my messy and spaghetti files with much tests, failures and dead ends, also vizualizations functions to produce that green maps , and faulty versions of them but you are right, I should add that

Just by reading your actual messages it's easy to see that you didn't write the blog post entirely by hand.

ok

Excellent write up and an enjoyable read! Reminds me of the “good old times” where posts on HN were written by humans and with a specific writing style like yours. You could’ve used a little bit more of geoguessing to narrow down results, or do a brute force visual check on the last hundred or so ;-)

agree! AWESOME work!
