bramble VS maplibre-gl-js

I've been looking into Nix a lot lately (but have yet to take the leap - I'll probably start with devshell)

But a couple of projects have come up lately that piqued my interest wrt syntax and alteratives (Since I am not sure about Scheme anymore than Nix (as a langauge) :-)

An alternative to Nix that uses Starlark (python syntax) instead of a purely functional programming language: https://github.com/maxmcd/bramble

I struggled to climb the steep learning curve of Nix/NixOS and wondered what it would be like with a more familiar (to me) syntax.

It's been very rewarding to write. I was able to implement some ideas from the initial Nix paper that aren't present in Nix. Nix is also quite dependent on the use of the /nix/store path, but I was able to allow a user to use almost any path for their build store without sacrificing on the potential for a shared build cache. I also want to have better native support for things like building docker images, among other features.

I'm currently implementing sandboxing and finalizing some of the build structure, but hoping it'll be usable sometime soon.

(.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

MapLibre GL JS v3.3.1

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.

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!

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]

The map is rendered by https://maplibre.org/, you can see how it is used here https://github.com/anvaka/map-of-github

Kudos to https://maplibre.org/ - amazing library
