Everything You Wanted to Know About Vector Tiles (But Were Afraid to Ask) 🗾✨

https://www.openstreetmap.org/user/daniel-j-h/diary/404061

I collected my thoughts on vector maps and vector tiles after having spent some time reading the mvt spec for the first time 🦧💡

Happy year of #OpenStreetMap vector maps! 🎉

Ended up building a progress tracker for my 2024 goal #Rowing the Atlantic on a #Concept2 🚣‍♂️✨

https://github.com/daniel-j-h/rowing2024

It's updating the map on a daily basis with my rowing progress based on the official Concept2 Logbook data via the ErgData app🎉

Map data #OpenStreetMap, map sdk #Protomaps & #Maplibre, GitHub Action for the daily cron job. All very scrappy, glued together 🫣

I publish today the free software #Jekyll #MapLibre (pre-release; MIT license) – a plugin for static websites for easy self-hosting of maps.

I proved to myself that privacy-friendly self-hosted (as opposed to #GoogleMaps in the cloud) #maps for displaying locations on websites can be accomplished in a few days with minimal resources. In the future, I will consider this as my new baseline when looking at #GDPR Art. 25 (data protection by design and by default).

Hard to believe it's the last #GISchat of the year! Thanks for all the fun conversations in 2023 and here's to even more mappiness in 2024.

To celebrate, I want to hear about your favorite mappy takeaways of the year! Lessons learned, cool maps, new GIS tools, whatever!

#30DayMapChallenge, day 1: Points

Social position index of schools in France, 2021-2022. This is the second version of a map I've published one year ago, with the following changes:

• The data is more recent (2021-2022 here, previous years are coming soon)
• The map now includes all types of schools (écoles, collèges, lycéesn
• On the technical side, I've replaced kepler.gl with #maplibre.

Work in progress, feedback welcome!

#Maplibre and #Protomaps are democratizing maps right now 😍

https://protomaps.com/ and PMTiles are brilliant - you can serve up a vector tile file of the entire world (100+GB) and have it display in browsers using HTTP Range header tricks to download just the subset needed for the current area

I figured out how to create a subset tile file for Half Moon Bay (just 2MB) and serve it using maplibre-gl

I genuinely feel like #Protomaps is not nearly getting the attention it deserves

https://protomaps.com

We can drop a single file on a static host and get stylable vector maps? Magic ✨

In combination with Maplibre it's a game changer for 99% of web map use cases 👏

i recently helped create a simple interactive map of public art in vancouver

made with svelte + maplibre

check it out here :)

Hey, #gischat !

I am thinking about making some custom web maps for my org using #MapLibre or something, but I have a question.

Is anyone using a static site generator for a #gis site? I have some SSGs that I like, but they seem to be better suited for longer, scrolling stuff, not full-screen maps.

Why is generating a bunch of map tiles for a small ~10km10km area still so complicated? #MapLibre #mapping #maps

I remember doing this several years ago, and it was complicated back then, now it has a few extra steps still with vector tiles.

Map video overlays are a thing! 🗺️✨😮

It's tricky, tho! I haven't found an easy way to

• geo reference footage; eye-balling video bounds right now

• add a video that's not just overhead footage looking straight down (footage at an angle)

• work with footage from a moving camera (counteract moving camera)

• cast the magic ffmpeg spell for webm transparency

Otherwise pretty cool!! 🎉

I remember when MapBox changed their license and subsequently Open Source version @maplibre was forked. I didn't follow the project after that, as I didn't have mapping needs at the time, but now that I looked at it, it has started very well.

#MapLibre now has a governing board and it seems pretty well run for an OSS project. Gladly checking it out now! https://maplibre.org/

Donnerstag ab 18 Uhr zeigt @seb_meier im #CartoHack wie man "reaktive" Web Maps mit #svelte bauen kann und vergleicht #Leaflet, #OpenLayers, #MapLibre/#MapboxGL (und vielleicht noch mehr) 🤯

Der CartoHack wird als Zoom-Videokonferenz, die Teilnahme ist kostenlos und du bist herzlich eingeladen! Wir freuen uns übers weitersagen.

I think one area where visionOS perhaps dropped the ball is MapKit. Rendering 3D maps seems like a compelling use of volumetric apps in spatial computing, and figuring this stuff out would also necessitate providing tools for view elements to make layout decisions based on whether they're running in a flat window or a volumetric context. As far as I'm aware, there's nothing like that on visionOS. A SwiftUI Map view is just a 2D map. There's both a user and a developer story here to be told

Anyone with #MapTiler experience? How can I handle overlapping markers coming from a GeoJSON source so that they have a proper distance added to each other?
