Hello,

At the moment, the LowZoom Tile generation works like this:
- lowzoom process takes some 12z tiles and compress them to a lower level tile

On this, or another, list, i've read about the idea to create special
12z tiles where only main routes (highway=primary) and some other
important things like big lakes/rivers/cities where rendered.

Whats the progress about this, is someone creating special style sheets?

An other idea could be a lowzoom api "extension".
With this extension, could be possible to define which objects
(nodes/segments/ways) to get. As example, only ways with tags
highway=primary or natural=water or natural=coastline or
place=village.
But it's also possible to download a much bigger area, as example 6z tile size.
With this data, lowzooom tiles could be rendred with the osmarender
and "normal" t at h clients.

What do you think about this idea?
