I don't know if the autorouting maps are editable in that manner, but I suppose if the map data was edited to to discontinue the road???
I've never seen info about one way road data!!!
So I can't comment.
What I was referrring to was the encrypted vector based images that each of the big three are using for the maps on the GPSr screen.
(Yes GPSr, the "r" means receiver, as a GPS is the actual system of satellites, groundstations...etc that makes the system work, not a reciever)
The images are not easily editable, even by your average joe computer geek!
There are usually complex processes of decompiling the image files, then using map creating software to re-create the maps, and then uploading to the GPSr.......(not easy, except that Garmin "geeks have an easier time of it).
There are a dedicated band if programmers/enthusiasts that have created the programs to do this decompiling, and recompiling, etc.....
You just need to know where to look!
The easiest method is(was) with the old Lowrance mapping receivers, that used MapCreate4.
Oziexplorer had the functionality to edit these maps, so a 10 year old GPSr could have updated maps forever!
OziMC edited the maps that are in the PC program, and then you uploaded the maps with the Lowrance MapCreate program.
Some of the map data on the DAST topo maps is crazy! (in Victoria)
They have "freeway" data to
Bendigo, even the road is not even stated!
Same with the Western ring road to Ballarat (DeerPark bypass). If you were navigating with this map, you'd be expecting to arrive at a freeway, yet it doesn't exist!
Not for a good 5 or so years!!
they are already pre-updated ;-)
But our famous Scoresby bypass (the "no more tolls" road that will be completed in '08) that is marked in dotted form, like a walking trail!
I just hope interstate travellers are sensible enough to realise that this is not a walking trail that looks like a freeway!! :))
cheers.
