Yes, while zoomed in that property is useful, zoomed out less so.

I think you need to think a little more carefully about the geometry involved.

Sounds like you need to think a little more about the use case of these maps.

You can't really switch projections mid-zoom, because the tile coordinates wouldn't match and you'd find yourself in entirely the wrong place.

Not a big problem when zooming out from say, North America.

Wow, it's so refreshing after using Google Maps. Wikimedia Maps are just fast. Reminds me of how I remember Google Maps being. (My machine is much faster now, but GMaps just _lags_.)

The data quality is a bit weird, as if it doesn't know what things to highlight. But I'm sure this will improve over time.

I am pumped about this, especially the Wikimedia Commons use cases described at https://www.mediawiki.org/wiki/Maps/Future_Plans#Commons.

There are actually already ways to browse Commons images on a map, but they need significant work. For example, the tile at [1] depicts an area with easily 20 geotagged Commons images, but, inexplicably, none of them are shown until you zoom in another level. Or, zoom out to see the entire state, only to see Massachusetts shown as completely lacking any geotagged Commons images [2].

There is a ton of potential for awesome applications involving geotagged images and geographic maps. I'm glad to see the Wikimedia Foundation stepping up its investment here.

Nice effort, but still needs a lot of work. This view of the western US picks out four coastal cities worthy of mention: "Tijuana" (fine), "Los Angele" (sic!), "San Jose" (err..) and "Calgary" (wat). No San Francisco, no Seattle, no Vancouver... https://maps.wikimedia.org/#4/40.15/-93.38 Scripts are also all over the place. Japan is Japanese only, China is Chinese only, India is English, Bangladesh is Bengali, Pakist…

If you're going on population, San Jose is the biggest city in the Bay Area; in that sense, it makes sense to pick it as the "one that wins" in a very dense area. Calgary is around 1M people and Tijuana is 1.3M, while Seattle and Vancouver are each around 600k. Those choices seem pretty reasonable to me.

In case you're wondering what this is about: the scale of Wikipedia makes it difficult to just drop in a third-party OSM tiling service, so they're rolling their own map rendering process using OSM data. This is a beta of the rendered tiles, displayed inside Leaflet. If you're into maps and this kind of thing, I highly recommend checking out LocalWiki ( https://localwiki.org ) too!

Is their rendering process documented anywhere?

Yes. From https://www.mediawiki.org/wiki/Maps#Production_maps_cluster:

The implementation [1] has various components including:

* Kartotherian [2]: a server capable of providing map tiles in vector (pbf) or raster (png) formats, as well as static map snapshots of any size for a given location.

* Tilerator [3]: a distributed backend tile generation service with a jobque

* A flexible sources [4] system to set up the needed storage and processing pipeline

Milwaukee loses the last letter too at certain zooms. Oddly nothing but the lake to its right though.

Eh, you can. You can even do actual 3D rendering in browser.
