Hi Charles: - Do you know how often TeleAtlas physically updates their maps
for the United States. I'm finding a lot of streets in different States
which are new established communities but the new roads are still not
identified within the GPS maps. For example; I have some friends who four
years ago purchased a home in a new community outside of Chicago,
unfortunately when I tried to create a royte from O'Hara Airport to their
home, their road was not listed in the Illinois maps. In today's world one
would hope you could get gps updated data that was at least less than 4 to 5
years old, a lot of changes can occur within that time span. Thanks.

Subject: [gps-talkusers] Re: UK MAP PROBLEMS
Hello Steve,
I am sorry you feel this way.
I can assure you we spent a great deal of
development working with roundabouts and UK
specific issues with 4.0. Yes there is room for
improvement and we are always looking for ways to
do this, as you said it would be nice to have
"take the 3rd exit" when dealing with
roundabouts, this has been noted in our feature requests.
Yes there are incorrect POI data from TeleAtlas,
all we can do is report the issue and its up to
TeleAtlas to fix it, and when we get the next set
of POIs from TeleAtlas hopefully they are
fixed. Incidentally I am currently trying to get
updated POIs for the UK but TeleAtlas has changed
the internal format of these POIs so now I have
to not only just convert the POIs to our format
but now have to develop a new intermediate
conversion utility that changes their new format
into the old format my software is expecting. So
I totally agree with you that TeleAtlas's
practices are someone in question here and am
also disappointed in their data quality. Sendero
may have to look into other options, which will
present itself with a whole new set of obstacles
and may trade on set of problems for another.
Also keep in mind Steve, that prior to 4.0 the UK
only had a very limited set of POI data, now you
have over 15 times the data as before, and some
of it may be bad, that is life, all we can do is report the issues and move
on.
As far as your comments on pricing goes, feel
free to buy those other systems and let us know how that works out for you.
Thank you
Respectfully
