mouse-scroll-wheel-acceleration-userspace VS maplibre-gl-js

If you want to have mouse scroll wheel acceleration, you might be interested in a small project of mine: https://github.com/albertz/mouse-scroll-wheel-acceleration-u...

I'm using this all the time on non-Mac platforms. Once you get used to this, it's hard to get back.

But I'm still waiting that such a feature gets more built into the core, e.g. libinput or so.

Regarding quickly scrolling around in a large document, there is also scroll wheel acceleration, i.e. the users finger scroll speed is not just a linear function mapped onto the software scroll speed but rather it can accelerate.

MacOS, iOS and Android have this anyway, and a few custom software as well.

I implemented a cross platform user-space variant of this, to get mouse scroll wheel acceleration. You can even use this in addition to the native scroll wheel acceleration on MacOS.

Turn on adaptive acceleration. Enable gestures. Look into this project that ports macOS-style scrolling acceleration to X11 and Wayland: https://github.com/albertz/mouse-scroll-wheel-acceleration-userspace

I never had an iPod, but I wonder, did it use some acceleration scheme? I.e. your physical scroll speed was not just linearly mapped to the virtual scroll speed but some quadratic or even exponential scheme?

Because I know that they do the same on OSX for scrolling, i.e. scrolling has an acceleration scheme, which I very much enjoy, and always miss when I'm on other operating systems.

For that reason, I implemented such scroll acceleration in user space. Some further details and references are in the README. https://github.com/albertz/mouse-scroll-wheel-acceleration-u...

Workaround: https://github.com/albertz/mouse-scroll-wheel-acceleration-userspace. Enables inertia in Chromium and Qt apps, but breaks it in GTK apps (fun!).

Good video, but I find https://github.com/albertz/mouse-scroll-wheel-acceleration-userspace a much better solution.

(.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
