Why does not TomTom feature elevation?

One feature that I miss from my GARMIN GPS is elevation

    Yes... that is a bit of a shame. I've not seen examples in any of the software implementations, so I can only come to the conclusion that it's not in the underlying map data.

    Happy to be proved otherwise though.

    Agree with you.

    It doesn't have to be in the map data. The elevation is part of the satellite triangulation. (Not as accurate than the Lat and Long but still plenty accurate for driving purposes.)

    Yes, and in GARMINs implementation you can calibrate it on a known elevation to get more accurate reading near you.

    ...but surely that's only going to tell you your elevation at the position you're currently at?

    It's not going to tell you - for example - of an upcoming gradient.

    What benefit to a motorist is that ability of a GPS to tell you what height you are at?

    I have a garming foretrexx 201 ( a sport watch of 2004 with elevation by GPS), i have free altimeter application on my smartphone ( a 200€ model) and the indication of elevation are very accurate.
    With panel in mountain pass or at the seashore, only beetween 0 to 5 meters of difference. It is a pity that Tomtom don't give this indication.

    "What benefit to a motorist is that ability of a GPS to tell you what you are at?"

    I have friends that claim that paper map is superior to GPS, I strongly disagree with them, but I will not challenge them. I have used GPS as long as it has been available for public use and have seen its development and learned to make the most of it. There are features that I do not find useful to me but know that other users appreciate them. One feature that I have valued all the time is height, not for navigation as such but similar to se buildings lakes and other thing on the screen that is hard to argue that they add benefit to motorist but add help you to se the landscape you traveling in, just like when you look at a paper map.

    I am not challenging that someone would like Elevation available on their Tomtom device my interest was what benefit do they get from that. I thought that the GPS units that do have it will only tell me what height I am at where I am I was not aware that they could also tell me what height I would be at at a particular point on the map or route.

    Right! Just to orient me in the landscape and answer the question, at what elevation are we at, not for London but driving in the Rockies or the alp this question come up frequently in my car.

    Right. If you want elevation of someplace else that's a whole different issue.
