OpenTopoMap VS maplibre-gl-leaflet

Have been using https://opentopomap.org for this for a while, and depending on what you're looking for it still has some advantages: does show the numbers on all height lines (osm only does the 50m one in my area for some reason, leaving you to guess whether the next one is 40m or 60m since that is not always obvious - seems like a key thing for a topographic map), does show the house numbers.

For example OpenTopoMap looks very similar to most maps that were in my school atlas. I like the MapTiler renderings too.

https://brouter.damsy.net/ The topo map is provided by https://opentopomap.org/ Alternatively, if you have an OSM account, you can go into edit mode on OSM website and drag GPX traces into the window to display them. You can't get elevation profile this way but you can use topographic map background or a better range of satellite imagery, and you can use Bing imagery without an API key.

The chances of the problem not having being already tackled with deterministic algorithms is the thinnest - and in fact, yes, there do exist tools, as expected.

See the sections about 'hillshade' at the OpenTopoMap "from scratch" instructions, at https://github.com/der-stefan/OpenTopoMap/blob/master/mapnik...

I have generated and hosted locally an instance of OpenTopoMap covering South America. Now I want to create a set of MBTiles for each individual country. Using the Raster tools -> Generate XYZ tiles (MBTiles) I can do that for a rectangular extent (drawn on map or calculated from layer). Can I do it for an irregular shape? I downloaded a .shp file for Argentina, for example - https://i.imgur.com/3IGJ88A.png

At my day job we’re heavily invested in Leaflet for historical reasons, but toward the end of last year added Maplibre as a layer on top of it via the excellent https://github.com/maplibre/maplibre-gl-leaflet. This has allowed us to begin transitioning gradually instead of being forced to jump all at once.

It’s hard to beat the simplicity of Leaflet, but neither it nor OpenLayers can handle Mapbox Vector Tiles in a performant enough manner, so Maplibre is the future for us.

On the Leaflet front, if you look at the plugins list, you'll see Leaflet.VectorGrid (made a long time ago by yours truly). And if you search for a bit, you'll find maplibre-gl-leaflet, which places a Maplibre instance inside a Leaflet map pane.

https://github.com/maplibre/maplibre-gl-leaflet exists!

It's not perfect, and you don't see the full benefit of a WebGL renderer, but if you want to keep using a Leaflet API, it's great.

Seems like MapTiler is maintaining an open source full stack vector alternative, and OpenLayers[0] looks good as well, so maybe it's time for legacy libraries to add vector support, or for users to switch libraries? There's even bindings from Maplibre GL to Leaflet [1].

I at least would find it interesting to see the two compared by someone other than me ;).
