The #30DayMapChallenge is an incredible project that runs every November. Participants create & share maps on 30 themes.
A well crafted visualisation can transform a "boring" section into something that really sticks with the reader, so I'll be checking our this year's entries for inspiration!

That said, I do recommend "Psychology of Intelligence Analysis" by CIA vet Richards J. Heuer Jr. It’s timeless for metacognition, perception, and avoiding bias. And you can access it for free at the CIA website: www.cia.gov/resources/cs...

Got a questions? I may have some answers.
I updated the text on the "Frequently Asked Questions", and on the "List of OSINT Exercises" pages on my website. Added new info, and removed some.
Improved? Who knows 🤷♀️
I think it looks better at least.

Last week I attended the #SIRIUS conference at the #Europol Headquarters at The Hague.
I talked about geolocation and all the exciting things we can do with it. It was great talking and listening to so many people interested in #OSINT. I just love all of it.
I even got a gift 😍

Over 50 photos of fugitives added to the #Europol website.
Maybe you've seen some of those faces around, or maybe you can use your #OSINT skills to track them down (and inform the police, don't contact them yourself!).
Some even come with rewards.
Happy weekend, happy hunting ❤️

Alternatively, you can also ask ChatGPT to create an overpass turbo to display them.
The top image below shows my request and the code. The bottom image is the script on overpass turbo showing the same electricity towers as previously seen in the f4map.
Both options are great.

f4map is an amazing tool which has 3D mapping of lot of structures, including power lines. I use it whenever I need to track them down quickly.
You can see the comparison between the f4map (top) and Google Earth (bottom) of the same location. Much faster to locate them using f4map.

I still haven't been able to get anything with "filetype:cvs", but it's just a matter of time.
