the application and its capabilities (render, navigator, etc..) but more for
the completeness of the informations that, indeed, coudl drive any kind of
application.
Looking from a more high point of view is a kind of life-loop: data exists
because there are applications that use them, and applications could exploit
new features only if the map data are adequately detailed.

Oggetto: Re: [OSM-newbies] Speed Limits
The most practical use of maxspeed on maps is to estimate the "travel
time" of a particular route in a gps map of a navigational device, rather
than just warn you if you are above the speed limit.
It's always better to use the conservative value (lower speed limit) to
estimate your travel time (so that the gps device can calculate and show you
that fastest route without breaking the max speed)

Howdy,
I'm trying to use maxspeed to put in speed limits for roads in my local
area.
One of the roads has a speed limit of 55mph if you are northbound, but
50mph if you are southbound.
Another road has a speed limit of 70mph in the daytime, but 65mph at
nighttime.
How should these be entered?
Is there a web-page that specifically explains how to enter these
situations into the editor?
