Hello to all of you people of mastodon! 🤗
This is my #introduction
Here I will share stuff and links that I would like more people to know, I will also try to write some reflexions and though on my projects. I live in Normandy, France. My current topics of interests are various: #programming #bike #osm #climatechange #selfhosting #freeSoftware #linux #maps #openstreetmap #wikidata #rust #python
I speak french 🇫🇷 and english 🇬🇧 .

If you're into map making geekery, this is a great Ted Talk about the biggest mistakes cartographers have made about the Earth's geography.

New Greater Northshore and MEGAMAP (Northwest King County) bike map update!
This version is very 1 Line light-rail focused, not just adding 1 Line stations but upgrading street labels for better wayfinding. It contains several other updates and two contributions as well.

All previous advertised permalinks remain valid.
I love that Kamala's pick for vice-president is a data and maps nerd. This makes me very, very happy. 👇

Finally finished implementing the classic 15 puzzle game but using the standard #OpenStreetMap tiles as the sliding pieces! 🗺️🧩
While there are many implementations of this game (some even let you upload your own image), as far as I know, not one directly uses OSM slippy map tiles for the pieces. I figured this would be a nifty side coding project and it was fun to do! 💪
Currently you can play any of 20 map locations. Enjoy! 🎉

There's been talk on the Fedi about why online maps like OSM and Google use the Mercator projection, and I think it needs a bit of clarification. (Do NOT snitch tag.)
Online maps are _mostly_ used at small scales, of a district or a city. At these scales, the earth is approximately flat, so users expect a map that is _conformal_, one that preserves angles and shapes.
Online maps are continuously zoomable from continents down to your house. They usually aren't rendered on your browser straight from vectors, but are batch-rendered offline into square tile images. If you're on a slowish Internet connection, you can see them loading individually.
As you zoom an online map, tiles get replaced with higher-resolution ones, and as you scroll, tiles get filled in to fill the gaps. You could theoretically scroll and zoom forever, so the map needs to not have a magically special reference latitude or longitude. These constrains mean that the map needs to be _equatorial_, so that no point gets special treatment, and _cylindrical_, so that meridians are vertical and lines of latitude are horizontal.
And which is the map projection that is all of equatorial, cylindrical and conformal? Mercator!

Last week we published a set of three in-depth #map reports covering territorial control across #Somalia's claimed territories from 2023 to present. The June 2024 report is free for all readers, and shows the height of "#IslamicState" (#ISIS/#ISIL) control in the country:
