A comparison of the level of detail and simplification for Belgium in the Natural Earth 10M data (shown in red) and in the World Bank official boundaries in blue

Interesting characteristics of this data set: periodically updated, explicit disputed areas and digitized at 1:250k scale. This level of detail makes it a lot more detailed than the 1:10M Natural Earth we are all using, and makes it suitable for country maps 3/4

Outlines of the Admin0 level administrative boundaries from the World Bank official boundaries, shown in blue

Outlines of the Admin1 level administrative boundaries from the World Bank official boundaries, shown in blue

Outlines of the Admin2 level administrative boundaries from the World Bank official boundaries, shown in blue

The first data set I presented were the World Bank official administrative boundaries, at admin levels 0 (country level, 263 features), 1 (3587) and 2 (39355). Already interesting to look at just like that, if you ask me :) 2/4

Waw. Where did you find this?

Machinery and vehicles are scattered across the terrain, with a central excavator near the middle. Dirt roads and linear patterns mark the landscape, indicating active industrial activity

A satellite picture of a large open-pit mining site with terraced layers of excavated earth forming curved and parallel patterns. The upper area shows light-colored terrain, while the lower sections reveal darker, systematically mined zones. The scene illustrates industrial-scale resource extraction.

Absolutely delighted to catch up with Xenographics, an initiative of @maartenzam.bsky.social. It was a big thing on Twitter some 4-5 years ago and I wish that the conversation would carry over on Bluesky. 📊

Hi. It's me. 2 weeks later. This is done. 58 frames over 3 seconds, *50* layers in the final image. WOO. This was a long edit, felt like ACTUAL work so unless I get it again with the actual sunset I doubt I'll be editing more like this. Psyched for the final piece tho! 🪶
