Xastir

I've had a hard time obtaining Canadian maps for xastir (APRS software for UBOs). The Natural Resources Canada department provides topo maps for free, from the Atlas Of Canada site

The maps usually live in /usr/local/share/xastir/maps and have subdirectories that reflect the areas of interest. The official documentation suggests:

World/
 Canada/
  Canada/Province/
 USA/
  USA/State/WA/
   USA/State/WA/County/
   ...
   GNIS/
   Overlay/

To do a download of the Canadian maps from NRCAN, navigate to the top level directory of interest and then execute the perl scripts that are included with xastir:

$XASTIR_ROOT/scripts/toporama250k.pl 
$XASTIR_ROOT/scripts/toporama50k.pl

If you haven't set $XASTIR_ROOT then you should just type in the $PATH to where it is installed. If you're not sure where it is, you can try to locate it.
