[mkgmap-dev] Slightly OT: TYP files, lines with borders

From Charlie Ferrero charlie at cferrero.net on Sat Feb 13 09:23:30 GMT 2010

Hi all,

Many people have created TYP files that define lines to have borders, to 
make them look more like paper maps (e.g. the UK's OS series).  This 
looks fine in Mapsource, but in the GPS unit things go horribly wrong 
(see screencap).  In effect, the GPS draws the border *perpendicular* to 
the way in question every time it encounters the end of a wayed segment. 
  Given that in OSM ways are usually composed of multiple segments 
joined together, this means that ways on the GPS are a horrible 
collection of little "worms" all joined together.  The resulting effect 
is unusable.

But as I say, this doesn't happen at all in MapSource (second screenshot).

Is this a known problem with TYPs, line definitions with borders and 
(certain?) Garmin GPS units or am I doing something silly?
