tippecanoe VS Leaflet

This is awesome. Such a great use case for nix.

I do a lot of geospatial processing in the cloud and I've been using Tippecanoe a lot to create vector tiles. It pairs well with PM Tiles for storing on the cloud. It seriously increases the web app performance for massive data sets. I queue these up with ECS tasks to process our json/csv/parquet input and create optimize vector tile outputs.

Tippecanoe would be a great addition to your nix packages. I've been thinking more and more about how Nix could fit into this pipeline.

Great work!

I'm the author of a few of the tools mentioned in this post!

A convenient new development is instead of using tippecanoe -> go-pmtiles to create PMTiles archives, you can now output .pmtiles directly:

tippecanoe -o bks2.pmtiles mainroad.geojson ...

This is available in Tippecanoe (https://github.com/felt/tippecanoe) v2.17 and later.

Thanks to Felt (https://felt.com) for supporting this open source work.

Things I have tried so far: - Just using native vector tile conversion as it involves feature simplification. Doesn't work since smallest feature just disappear, resulting in blank regions instead of "averaged" regions. - Using tippecanoe's built in features to drop/merge in densest zones. Results are disappointing because of unexpected (and too big) differences between each zoom level. - Rasterizing the map, sieving, then vectorizing with smoothing. Doesn't work because pixel information are mixed. I would need a way to rasterize while preserving the land-cover category (with some kind of majority filter ?), but haven't find a way to do this with any QGis built-in or plugin feature.

Take a look at Tippecanoe, which is under active development again[0]. The original developer, Erica Fischer (who is wonderful to work with), has a fork[1] where new work is happening.

9. Leaflet

Leaflet is the most famous open-source map library, with lots of plugins. 2 of them are used to animate a marker on the map:

Leaflet stands out as one of the top open source JavaScript libraries for crafting interactive maps. Optimized for both mobile and web devices, it is relatively small (around 42KB) and offers a ton of features, plugins, and a straightforward API. It works across all browsers and platforms.

Finding maplibre 'better' was more valid at the time than today, and is also subjective. The creators and maintainers of both libraries have done some great work (and are still doing so).

Back in January 2022, the stable version of leaflet, v1.7.1, was from September 2020, and was affected by some small bugs degrading the user experience. Although the release of following version seemed close, there was no clear schedule for it, and I had concerns about how maintained the library would remain.

As of today, the bug from 2015 where there is some white space between map tiles on fractional zoom levels [0] is still open.

Also, leaflet was a pain to integrate in Svelte Kit framework, because it depended on `window` and-or `document`, not available at server side.

Maplibre, on the other hands, with a feature set roughly equivalent to Leaflet, benefited from much more frequent releases, and seemed more stable across browsers and devices. It was also easier to make it work in Svelte kit.

For a personal project, I had to use Leaflet with Svelte, and I faced some problems during development.

Do anyone have any workaround on how to get leaflet js to work inside notion, either as an embed or as code, or widget? https://leafletjs.com/

None of those things are what most in the GIS space would consider "complex", so you could go with any of the options you selected. For lightweight maps, I like Leaflet

https://leafletjs.com

I have a special place in my heart for Leaflet and it’s documentation: https://leafletjs.com

Its suppose to be free: like with map data providers there's Leaflet, OpenStreet Maps and many more which are all for free.
