in reply to Using GIS/Shapefiles with Perl Tk Widgets

Have you googled for Perl Tk GPS There is some stuff out there. I would think the big problem would be to stitch the edges of the underlying image containing the road info together to make it seamless.

I also would consider using Tk::Zinc instead of the Canvas, since it makes rotations and zooming easier. Zinc is used primarily for Air Traffic Control so I would "assume" it lends itself to using GPS. You might want to ask on the Zinc maillist.

Just for fun, I started something like this, see Tk Zinc Drone plane control. It dosn't have road maps and GPS..... all I need is some funding. :-) But I'll bet Northrup has beat me to the money. :-) See UAV's

      How are you trying install it? From the module on CPAN, the downloadable tarball from TkZinc.org, or an RPM for some specific distribution? Zinc was originally made for TCL, but has been ported to Perl. If you use the module from CPAN, it should work. The tarball from TkZinc.org is designed for TCL and has a special subdir for building the Perl/Tk version.... read the README that is in the Perl subdir, run export2cpan, then build according to instructions.
