tippecanoe VS omapsapp

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.

There is a beta of Organic Maps for Linux. Check out bottom of this page: https://organicmaps.app/

I would still want to to know if I can selfhost something of similar, low complexity in my home network.

I live in a country in Europe where roaming is prohibitively expensive, so use offline OpenStreetMap abroad a lot, with different apps, mostly https://organicmaps.app

https://organicmaps.app/ is well suited for (completely) offline routing.

Personally I am using [organicmaps](https://organicmaps.app/) which is using OpenStreetMap data, and it works really well.

... right now your bookmarks aren't synchronised anywhere so if you lose your phone all your bookmarks are gone.

When that's working I'll change over in a second!

Organic Maps is offline until it needs to download updated map information from Open Maps data.

Search just finds whatever matches sorted by distance so it may not fit one's needs.

Maps.me (iOS, Android), or the 'non-commercial' version of it Organic Maps (iOS, Android). Both apps are free.
