What the hell, here are a bunch of half-baked ideas that I haven't made time for because I'm lazy and stressed out and exhausted:

1. Designing a protocol and air interface for an amateur radio cellular network. This started out with some spread spectrum experiments and an interest in low-probability-of-intercept (below the noise floor) communication. The idea I have now is sort of a cross between APRS and DMR using modern modulation techniques. The network would consist of amateur rooftop "cells" with internet connections, and mobile transponders that communicate with those cells. There'd be some sort of callsign or key based addressing scheme and IP-like network topology discovery. Everything will be authenticated. I'd love to have an encrypted mode, but unless the laws change, it probably isn't going to happen.

2. Open-source firmware or gateware implementation of a USB PD controller that supports entering/exiting alternate modes properly. Inspired by Kate Temkin's Luna project [1]. I got the impression that PD was out of scope for LUNA, at least for the time being, but it would be really nice to have both a USB and PD stack that could be integrated onto a small, inexpensive chip without the proprietary mess.

(.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
