Try opening all of them and seeing if you see any GPS cordinates 32.87711208 or something like this....

While it's true that many packages use Navtech data, it's also true that Navtech typically delivers the data in whatever format their customers' specify. This means that it's generally not possible to move data files between GIS software (without some conversino).

I suspect that the various files you see are probably metadata and/or index files to assist the OEM software to more quicly process the ALLDATA.KWI file. Moreover, it's likely that ALLDATA.KWI is compressed (or at least contains compressed data fields). Do an ASCII filter of that file. That should quickly tell you if there's any hope of extracting the POI info you want.

@0l33l: don't you think the lat/lon info will be binary encoded IEEE floating point instead of ascii encoded (assuming for the moment that compression isn't an issue)?

It's already been done, its not worth it. The mapping software that we use in PC and Car generally baught map/data from a different company, most likely "Navteq" then programmers plug the maps, they baught, in to thier software. Check This Out

That link brings you to an active x control, designed to show raster based maps. You can buy the control... all you need it raster based maps. Check Here For maps


Generally, the maps we all use weather thier in PC,PDA,WEB BASED,CAR NAVIGATION are all the same they come from the same place, the only difference is the software running on top of the maps...

And yes, there is converstion software already design... Check out the US GIS (Geographic Infomation Service, I think ?) web site, they have a software development section that explains in DETAIL how to convert these maps.

You all are talking way over my head, I know nothing about this. However, I don't see how these are the same maps, they look entirely different and more acurate too me.
Anyhow, I'm at work now, nothing much I can do. I am working on getting the latest Lexus software with 11 million POI's and even "prettier" maps. Should have it Monday (maybe tonight). Maybe we (you guys) should study that instead? (since it's the latest version)


EDIT: Got It!!!
Same type files...screen shot next post (deleted)
EDIT AGAIN: I only got the latest Version of generation 3, which is still the same as what I showed before.
I am going to work on getting the Gen.4 dvd, I hope someone can pick it apart. It's got what HD was talking about in post#8 and it's got the 11 million POI's.

OK, I got the generation4 Lexus Nav. DVD. It's got 11million poi's. It would be nice if we could use these/import these poi's into iGuidance/Routis or whatever gps software. If someone wants to work on it, I can send them a DVD. Let me know here, or pm me.

anybody?
