maplibre-gl-js VS mapbox-gl-js

(.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

Good. Brave's fiddling with WebGL causes >50% of my bug reports from 1% of users.

Laravel and Mapbox GL JS

It originated as an open-source fork of Mapbox-gl-js before they switched to a non-open-source license on 8th December 2020.

Do you have programming skills? MapboxGL JS is a great library for stuff like this, you can really easily add a layer of GeoJSON data to a map. If you're looking for something less technical Google map lets you create custom maps where you can add a bunch of pins.

From the latest commits (not released/stable yet): git clone https://github.com/mapbox/mapbox-gl-js.git yarn install yarn run build-prod-min yarn run build-css Then use the generated mapbox-gl.js and mapbox-gl.css files. See CONTRIBUTING.md for more details.

> too bad it doesn't come with some code

Mapbox changed the license of their code last year I think to a proprietary one. https://github.com/mapbox/mapbox-gl-js/blob/main/LICENSE.txt

It requires a mapbox user license with billing enabled to use this code, let alone make modifications. But the source is viewable on github.

The software stopped being open source from v2 onwards. The new licence makes it merely shared source.

This GitHub issue where this change is announced provides a number of more in-depth explanations why this is a bad thing for most users of the software: https://github.com/mapbox/mapbox-gl-js/issues/10162

It's a bummer mapbox isn't open source anymore, now you're (and lots of other peoplare) are stuck pre-2.0.0 :(
