Hi Brett,
In some cities TeleAtlas data is far superior to Navteq data, plus we
have over 12 million POIs from TeleAtlas in North America which is
about 5 to 10 times the amount of POIs than Navteq, so this is
currently why we are getting our maps and POI data from
TeleAtlas. Besides there is licensing fees to pay so we can't just
get our maps from one company and the pois from another. There are
also other issues where they won't sell their pois unless you also
purchase their maps. So yes if we really wanted to buy both sets of
maps and POIs but then we would then have to pass on the cost to end
users and you would be paying a lot more which wouldn't fly
either. So as they say we are between a rock and a hard place.
Thanks
Charles.

Hi,
Just curious, if TeleAtlis seems to have quite a few mapping and POI
problems, Why is NavTech not considered or used, since consensus
seems to be that Navtech is more accurate, according to reviews I have red.
Cheers,
Brett.

Subject: [gps-talkusers] Skewed POI Data
Hi All,
Sadly, the Version 5 POI database is still very skewed in my home
area. My church, for example is about 500 feet off from the POI
data. My home is at the wrong end of the block. Starbucks should
be on the corner of 1st and Main, but when I go to 1st and main in
virtual mode, Starbucks is 107 feet away. Loney's Harvest Food on
South 2nd is more than a block away from its actual location. If I
place my virtual location at 2nd and Morton, the real Loney's is on
the southeast corner of that intersection. True enough, the actual
store is set far back from 2nd Avenue with its parking lot in front
of it. However, the GPS POI places it north of Maple, 782 feet
north of itself.
The POI data for my Hair salon, Special FX, is in close
approximation with the POI data for Loney's and this is also far
off. In reality, it is near 2nd street in the Loney's parking
lot. the POI is, indeed, near Loney's, but this puts it more than
a block away from itself.
The YMCA is on the southeast corner of Birch and Park. The POI
data puts it >100 feet away, North of Birch on park.
some businesses seem to be close to their actual location but on
the wrong side of the street.
The map indicates that Birch Street does not go through at 2nd. It
indicates that the intersection does not line up, but in reality it
does. There are many streets that do not line up here, but this is
not one of them. I would still say that the database is still so
confused here that it makes the GPS POI data of little value. What
can be done to correct this? I thought that Tele Atlas was to have
come here to check things out.
Would it be helpful if I visit several businesses that I know to be
off and set a user POI and send the file to Sendero, would this
help fix the problems?
Please know that these are not isolated samples. They are just
places where I am vary familiar and can easily visit them in
virtual mode. I purchased this upgrade very hopeful that the
anticipated corrections had been made to the map for my area.
