[HOT] "OpenUnpavedStreetMap", "South continents", Colombia, soon Philippines

[Mikel Maron]

This is great!

Suggestion: highlight the unpaved roads ... the rendering is very subtle now. I'd like to be able to look at a city, and at a glance, get a sense of where the unpaved roads are.

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

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

>OSM.org Mapnik layer is in the menu for easy comparison on the current
>area. A "hybrid map for mappers" - and for soon-to-be mappers who can
>see what might be missing on the map ;) - is available by overlaying a

>Google satellite imagery is also available as a reminder, by comparing
>imageries location, that it is often advised to adjust Bing offset

>The database is updated at least daily, and minutely for the next days,
>after the new coverage will have been imported.
>Tiles are available from

>The current bandwidth is limited, but if you are interested, let me know.
