Show HN: Interactive 3D Visualization of the Shared Mobility Traffic in Berlin
Hello HN!
Over the last year, I crawled and stored the position of all available bicycles of a large shared mobility provider in Berlin, Germany once a minute (~2.1 billion data points). Subsequently, I calculated 713,562 trip routes as they were likely taken by customers of the provider. The web app linked above provides more background information and visualizes some patterns I find interesting.
All 3D map layers are implemented with deck.gl (https://deck.gl) and projected on a MapLibre base map (https://maplibre.org). The base map uses self-hosted OpenMapTiles vector tiles (https://openmaptiles.org). I store all data inside a Timescale/PostgreSQL database (https://www.timescale.com) and perform most transformations via standard SQL. All of this is self-hosted on my bare-metal server at Hetzner (https://www.hetzner.com).
The source code and a short demo video is available on GitHub: https://github.com/laurids-reichardt/berlin-shared-mobility-...
I’d love to receive feedback and answer your questions!
DISCLAIMER: Searching for collaboration opportunities for my master thesis.
I'm currently completing my master’s degree at HTW Berlin and would like to collaborate with an innovative company on an exciting problem or business case for my master thesis. I’m open to both remote work or on-site in Berlin.
If you could imagine providing an exciting opportunity in the fields of data engineering or data analytics, or have a tip who might, I'd love to get in touch with you via any of the contacts listed below.
Alternatively, leave a comment with your e-mail or contacts, and I’ll send you a message.

Protomaps – A free and open source map of the world
(.shp .gpkg ...) | ogr2ogr -> .geojson | tippecanoe -> .pmtiles
for OpenStreetMap data there's planetiler[4], and and openmaptiles[5] styles that work with Maplibre
with those combinations you've got a great start to something you can host for pennies on AWS S3+CloudFront or Cloudflare R2, with an open source data pipeline

New Map APIs from Google
Does anyone else have a solution for the satellite layer? I was using MapLibre [0] then needed direct-on-the-ground images which made me convert to Google Maps.

Use 3D map library with API key function of Amazon Location Service
When using the Amazon Location Service, I recommend MapLibre GL JS, which I introduced in my previous article, "Amazon Location Service and AWS Amplify to Use Various Map Library," but you can also use any map library you like, including iTowns this time. I hope you will choose the map library of your choice, including iTowns!

Using Lidar to map tree shadows
Your browser has a very powerful image decoder built into it, offloading the PNG decoding into Javascript is very resource hungry.
Using maplibre (or any map viewer) you can load blobs of image data out of a tiff and use `Image` or `Canvas` to render the data onto a map.
Its even easier if the tiffs are already Cloud optimized as they perfectly align to a 1-to-1 map tile and they don't need to be rescaled, you can then just render the images onto the map. eg here is a viewer that loads webps out of a 15GB tiff and uses Canvas to render them onto a map [1]
Unless you are trying to layer all your maps together, you also could stop reprojecting them into webmercator, or if your goal is to layer them, then storing them in webmercator would save a ton of user's compute time.
There are a bunch of us that talk web maping and imagery in the #maplibre and #imagery slack channels in OSMUS's slack [2]
