Map rendering question

 

I was visually comparing the map rendering on my Nuvi and a Nokia E90. The Nokia uses Tele Atlas maps. It made me wonder about who is responsible for the rendering of the maps? Are the map providers in any way responsible for rendering the maps, besides just providing the data? To me the answers seems to be 'no'. But I thought I would still ask. I seem to like the rendering of the maps on the E90 even though the app is not very usable while you are driving in the car because of screen size, fonts, and menu navigation system that is provided.

I think you're right.

There are quite noticeable difference between the way my StreetPilot C510 and Nüvi 310 render the same map. (As in different colours, different objects appearing at different zoom levels etc). If you add Mapsource into the equation, you get yet another flavour, of course.

Recently I completed first serious attempt at a map of my own (a roadmap of Malta). The differences here were even more pronounced. My theory for that, was that I was making references to elements that neither unit could actually display, and they were making different substitutions.
BTW - this exercise gave me a new sense of respect for the cartographers at Navteq :-) ...

My next project is a map of one of the UK's Theme Parks...

Navteq has a video showing some of what it takes to make maps. While it is a promotional video for the company, if you watch carfully it will show part of how they make there maps.
