    Has anyone played with Delorme Street Atlas? This does turn by turn, not had a chance to look at SDKs though.

    i had rerouting all done. You just touch a button and it would plot a new route

    Ok.... So let's go back to the beginning here. I think most people agree that Mappoint is one of the better products. The reasons against Mappoint were:

    I have decided that mappoint sucks too much to even be part of mediaengine. Its unreliable, the maps don't match current roads, and sometimes it looks like you are driving off the road out in the grass somewhere.
    1) It's unreliable
    2) The maps don't match current roads
    3) Sometimes it looks like you are off the road

    ...1) What is unreliable? It's database is the widest used and therefore is going to the most up to date available.
    ...2) The maps don't match current roads. Obviously using version 2004 we would hope that it is pretty up to date. With the web services, up dates should be available.
    ...3) Sometimes appear off the road. This is a general GPS inaccuracy, GPS is not allways going to be accurate to a couple of meters. Agreed, Mappoint does not have a snap to road function.

    So, let's gather requirements. Reading through so far, I think we are wanting:

    - Turn by turn instructions
    - Voice
    - Rerouting
    - Accurate maps / updates download
    - GPS:
    * Current location (state / road / etc.)
    * Current location Long., Lat., Alt.
    * Speed & Heading
    - Distance to next turn
    - Next turn graphical indication (i.e. graphic showing fork left, fork right etc.)
    - Support multi countries (US, UK, Canada, Europe)

    Skippy i would say you just about summed it up. Two things regarding voice:

    Voice recognition - terms like "where am i" "what is my next turn" etc...
    Voice prompts - (ability to enable or disable) "turn left at next intersection - Smith st." etc

    Also when voice prompts come on, music volume is brought down (should be a fairly simple addition)

    the reason why carcomp is not using my mappoint code is mainly because of turn by turn. As of this point it just doesn't work 100%. I believe when he was out testing it wasn't even switching to the next turn even though he made the turn. I did a few 8 hour road trips with it and it was about 85% accurate in knowing when the correct turn was made.

    Ok, so how can we make it more accurate? What machanism is used in your code to determin when a turn is made? Maybe we can improve upon this or even think of another mechanism. I guess that this turn detection functionaliy is implemented in your code as it does not exist in Mappoint. Therefore, the way I see it (at the moment) is we are dependent on:

    1) Reliability of the GPS
    2) Reliability of the Maps
    3) Sensitivity and accuracy of the turn detection system

    1 & 2 we do not have any control over, however, we could take a look into 3...???

    Regards,

    Andrew

    I agree with that i don't see how things could be off if we are using our own app and not mappoint itself. Mappoint is the most extensive mapping system around to my knowledge. note: mapquest.com is based on mappoint.

    Back in 1997 / 1998 I used a product called GeoConcept. This (at the time) was the best product around in terms of SDK and functionality in the cartographic world. Shall not go into too much detail, but I was developing a soil analysis system for the French Goverment.

    This is very widly used, however, with our needs, we need both a substantial database, good SDK and good route finding functionality (plus all the other sutff I mentioned above).

    ryguy: Any chance I could take a loook at what you have developed? Maybe discuss with you the way you've designed it and see if we can come up with any mods etc.
