  • hacking gps datacd

    Hi all,

    I was wondering if anybody knows off gpssoftware which is easy to hack?
    my problem is: I want movingmap software which is kinda 3d on my tft, but I want it also to output to a lcd showing just me the direction by means of an arrow or something.
    Since I don't think such software exists I want to write it myself, problem is that I need the maps with locations, adresses etc. Also I don't want to write a "from to" algorithm since people much smarter than myself have made something like that.

    So what I basiccaly want is a database with maps, coords en functions which I can access.

    anybody?

      Good Luck - I was looking for the same thing until I just gave up on the project

        What kind of LCD do you want to display it on? Alphanumeric?

        I have a VB app that without to much tweaking will do what I think you want it to do. I was going to use it to display my direction via a GPS receiver and some engine information (MPG, etc.) via OBD-II and display all that on a little 2x16 or 4x20 alphanumeric LCD.

        The only foreseeable problem with that is that only one program can access the serial port at a time, so it makes it hard to use a commercial GPS program with it.

          well the arrow wouldn't be a problem, I'm using a graphic lcd 240 x 64. The real problem is I want to outpput to both my lcd as my tft. on my tft I want moving map, on lcd the basics.

          I have a navtech cd from a BMW 328, but it seems the single data file contains multiple ".gz" files I don't know how to "cut" the single datafile into the different files so that I get normal .gz files which can be unpacked. the gz files are compressed ".gdf" files.there is enough information on the web to decode de gdf files but zero on the "multiple zips in one file" problem....

            Hey ZipLock, mind if I take a look at that VB program? I've been wanting to display GPS info on my char. LCD, this sounds really interesting. You mentioned that the prog will only access one COM at a time - my LCD is serial (matrix orbital), so not sure if this would be a problem.

              That would be seriously easy using Mappoint 2002 and VB. The big downside is that the maps are North-up only, you cant rotate it to be heading-up. I was going to use it until I found some decent software to use. Mappoint is expensive, but MS do a 60-day trial version with all the map data.

                Yeah.. I was hoping that I would be able to output some info like heading longitude and lattitude to my char lcd.

                Too bad mapmaking is an involved and expenisve process or we might have some freeware ap that you could write a plugin for.

                  It wouldn't have a problem with that. The problem would be if two programs tried to access the same gps on the same serial port at the same time, which isnít possible at this time. Hence my post earlier today, http://www.mp3car.com/vbulletin/show...&threadid=9916

                    You can get free raw mapping data from the US census. They are called Tiger/line files. I downloaded the 6 or 7 cd's full of data, I have been messing around with it for a long time and I have found it to be very hard without a GIS background. I was trying to get it to work with a program called MapServer, http://mapserver.gis.umn.edu/ so I could make some phat web based maps with GPS data, but I havenít had much luck getting it to work.

                      Ziplock, would you mind telling me where you downloaded these files? are they vector based?

                      I've been trying to "hack" a navtech CD used in a BMW gpssystem, but had no luck. Seems the main-file is composed out of multiple compressed files, I have no I idea how to "uncompose" them so that I have all the .gz files individually..

                        The census bureau charges $60 per cd, but once you get that cd you are fully authorized to redistribute it, that's how it can be obtained for free.

                        Or you can download it for free, they hide this pretty well:

                        ftp://www.census.gov/pub/geo/www/tiger/tiger2k/

                        I'm not sure if they are vector based or not. All I know is that they need a considerable amount of conversion before the data can be of any real use. Also, the maps tend to be less accurate that what you are probably used to.

                            don't know about the 3d part, but have a look at GPSS for windows.

                            Free for non-commercial, includes limited maps, and has map downloads for some areas, plus advice and info about converting other maps.

                            Might be able to do what you want.
                            Includes a demo mode if you don't have an NMEA GPS system attahced, and must be registered to get rid of an annoying message. Registration is free for private use.
