The area covered by OpenUnpavedStreetMap now includes all of Asia, and
some European countries: those in Former Yugoslavia, Slovakia, Belarus,
the Baltic countries and Albania. This is in addition to Africa, Latin
America and Oceania that were already covered.

A new domain name, ousm.fr, can now be used as a shorter replacement for
"osm.arkemie.org/ousm" in the previous URLs, such as in the message
quoted below.

Thus the global map is available at:

Views pre-centered for some countries are available, with GeoRSS feeds

or without:

More pre-centered views could easily be added on request.
Zoom level can go up to 21.
The database is updated minutely. You can force re-rendering of a tile
with /dirty at the end of its url.
Please be patient if you are the first to visit an area that has not
been cached yet.

Best wishes,

> Following Humberto's suggestion, flood_prone areas are also rendered

> Following a suggestion from Federico, and a need that had also appeared

> Google satellite imagery is also available as a reminder, by comparing
