#hexagons

0 posts0 participants0 posts today

Have begun making tiny hexagons for my stupid mental health, as the meme goes. I'm really enjoying them so far.

Not sure what I'm making with these, but I think it'll be a new case for my power bank. My last one went a bit wonky in the wash because the wadding detached. Whoever made it really did not think that part through (it was me, I made it).

3. Generate centroids from the output of #2 (either using the Centroids algorithm or Geometry generators).
4. To speed up and automate the process, I created a model that runs steps 1-3 above.
5. Style the output of 3 using: marker = hexagon, size = depends on population, color = depends on hazard level (Var). Utilize data-defined overrides/Assistant.

30 DAY MAP CHALLENGE 2024 | DAY 4 - HEXAGONS

Population ⬡ Flood Hazard
- larger hexagon = more people in the area
- redder color = higher hazard level

DATA
> Population density for 400m H3 Hexagons [Kontur] - data.humdata.org/dataset/kontu
> Flood hazard (100-year rain return) [UPRI/Project NOAH] - drive.google.com/drive/folders

@mdione I’ll see if I can explain why I personally like H3:

1. “Hexagons are the bestagons!” —CGP Grey

2. Icosahedral grid is based on Buckminster Fuller’s Dymaxion map, which I like.

3. H3 cells are more-or-less the same area across the globe which can’t be said for plain hex grids overlaid on non equal-area projections.

4. While H3’s levels of resolution are not 1:1 composable with adjacent levels, they did design it so that the cell vertices stay fixed.

#30DayMapChallenge Day 4 #Hexagons comes from @haavardaagesen showing the locations of geotagged Tweets from cross-border movers in Europe during 2021–2022. The data is used in the #BORDERSPACE project lead by Olle Jarv to study cross-border mobility.

Study of the mobility is crucial in the #EU as the #Schengen agreement allows for free mobility between member states resulting in little official data on the characteristics of cross-border mobility.

🗺️ Day 9️⃣:

Here is a stylized map of the former (), famous for its hexagonal architecture. This airport had been Berlin’s main airport until it was replaced by the new (and long overdue) Berlin Brandenburg Airport (BER). Coincidentally, TXL had its last commercial flight on 8 November 2020, almost exactly 3 years ago. The site was then repurposed as the Urban Tech Republic, a tech hub and startup incubator: urbantechrepublic.de
