We all have seen the small watermarks in the corner of many web maps in the past. But what does this all mean?
NAVTEQ and TeleAtlas are the main players. They both provide mapping data to GPS manufacturers and online mapping services.
GPA Magazine has a very good discussion of them.
Fletch concludes that NAVTEQ is the better choice (in the USA). It is a bit more expensive to the GPA manufacturers.
Frankly, when choosing a navigation device, I can hardly think of anything more important than having current and accurate maps! Until I hear otherwise, I say NAVTEQ is the way to go.
Here is a good blog article about Google decision to move to TeleAtlas.
