  • Ditching Mappoint.

    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.

    I am going to support destinator as the embedded gps, and also allow the user to launch any GPS program of their choice (although it won't be embedded in the app).

    Here is a screenshot of current progress. I need help knowing if I have the latest version (2.0.6 for PC) NOT PDA... I know they are releasing 3.0 soon but will what I write "now" work with 3.0? If you know the answers please respond. If you are not sure, don't bother answering these questions. I need definitive answers for this or i'm not going to be able to get anything done.

    No answers to any of your questions really, but just a question of my own. Why does it show the red dot as driving "out in the grass somewhere"? I thought you said that was the fatal flaw of mappoint but now I'm seeing the same thing with destinator on your screenshot...

    I'd say overall good decision though, considering mappoint doesn't support automatic rerouting and voice nav by default (without plugins). And the text is kinda small when you wanna configure it or enter addresses. Haven't tried Destinator though so maybe I'm speaking too soon...

      GPS error

      For the most part any gps software i used on my computer was always off. This is the way almost all public gps units come. Only military spec gps units are dead on accurate. My pioneer gps software actually uses a secondary program to lock you on the road you are driving on.

      I would blame it on the software yet, we need to "calibrate" the gps unit to correct the prgrammed error. A friend of mine said that they sell gps units that take the gps signal and also triangulate off signals from cell phone towers to get dead on accuracy.. any ideas?

      I got the same thing on Streetatlas, Ms Mappoint.

        The reason the above image is off is because i did not have a GPS unit attached to the PC when I took the screenshot. I didn't even pay any attention to where the dot was. Also, Destinator has a "snap to road" feature similar to Copilot.

          All new GPS equipment is dead on accuracte, has been for a few years now. It used to be only accurate to 300 feet or meters (I cannot remember) so now it is the softwares fault if you are driving through buildings and whatnot. Either that or you have incredible super powers.

            No software gets all the roads right. It's basically an impossible task- unless you want to pay thousands of dollars for map data. Some programs implement a "snap-to-road" feature to fake you out into thinking you are always driving on a road I think, personally I would rather use software that didn't lie to me to make itself look better.

                300 feet?, you crazy? a few years back GPS was slightly less accurate, but never any where near that number. Before WAAS came up GPS was only accurate to 10 meters. What your talking about though was the regulations that the government had put on the GPS system. They didnt want the technology to be used for something like homemade missle guidance systems so they designed the system to send out random crap data every so often, that way if a missle or something was trying to use GPS for guidance, it would get all lost when it got the crap data and thrown off course. A few years ago, they disabled this sytem because they didnt feel there was a threat.

                So its not that it ever was inaccurate, it was more that it would be temporarly innacurate and it would just seem like your GPS went insane for a minute.

                  I agree with your decision.. No need to reinvent the wheel. There are plenty of GPS applications available, and integrating them seems to be the best bet.

                  I personally love Routis, however, whenever I try to run this from Media Engine, it gives me an error loading (something about missing sound files), and Media Engine crashes. It works fine when its run by itself.

                    CarComp,

                    If you need any help with Destinator, please let me know. I've been doing LOTS of stuff with Destinator recently, and am starting to get to know it very well

                      GPS accuracy:

                      Ok, regarding the accuracy of GPS. Up until 3.5 years ago, the accuracy of a non military system was based upon the current state of the US.

                      Military systems prior to 3.5 years ago would be 'keyed'. This is a crypto graphic key that would be fed into a military used GPS system. These keys would only be available to countries within NATO. The keys would enable the GPS receiver to decypher the encrypted part of the GPS signal, which would contain the current timeING offset. The receiver can then use this offset when triangulating the result.

                      So, around 3.5 years ago, the US government stopped applying an offset which meant that the GPS data is accurate to approximatly 2 metres, depending on FOM value (Figure of Merit). Just incase you are interested, I had a keyed system running next a non keyed system some years ago and some comparisons of the keyed result, compared to the non keyed result.... Generaly there were only around 3-5 metres different in the accuracy. When they started bombing another country, this value changed substantially and varied considerably and continiously. I can't give information regarding this variation as it is classified. I also presume that they have the ability to 'turn this back on'...

                        On the destinator note, the maps look sh1t.

                        What other options do we have?

                          CoPilot does this.

                            hopefully he will also support mappoint. The problem with mappoint is it does not do turn by turn I had to hack a way in mappoint to get it to work and its not 100% working. It has some issues if two turns are very close to each other.

                              Was it giving you audible turn by turn or just visual?
