dug VS maplibre-gl-js

Just joined the sub after coming across it dozens of times while learning things to help my homelab. My first post is a shameless plug for a CLI tool I made that quickly helps users get an idea of how much their DNS has propagated. I use it all the time for my self hosted stuff (recently when i was playing with external-dns) and wanted to share to see if it can help anyone else. https://dug.unfrl.com https://github.com/unfrl/dug

For people who want to understand, learn about, or stay on top of their, DNS check out dug. Its a cli tool I made to help visualize DNS propagation but is a great learning tool.

Good article, totally correct that that is how to definitely 100% get the correct answer.

The bottom of the article, with 'other ways' got me thinking that another way to get what is very probably the correct answer is asking a bunch of other DNS servers what they think the correct answer is.

Using dug (https://github.com/unfrl/dug) like: dug -q NS jvns.ca

Gotta post this every time theres a big DNS issue, which seems daily now.

Check out Dug! Its a global DNS propagation/monitoring toolon the CLI: https://github.com/unfrl/dug/

This release is primarily focused on the 'Watch' feature (-w, --watch) which allows users to monitor their DNS propagation in realtime.

(.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
