Subject: OpenStreetMap e-mail - mkgmap bug report

Hello Steve,

Marvellous piece of work, mkgmap! Incredible, really. Although, naturally, there are a few glitches and here's one of them.

It could be that there's glitches between the connections between two parts of a map (as I'd guess that the position is somewhere between two sub-maps), but I'm not 100% sure of that.

This http://tile.openstreetmap.nl/?zoom=17&lat=52.01375&lon=5.11781&layers=B00000FF is the position on OSM, and this http://valentijn.sessink.nl/temp/CIMG7132.JPG is how it shows up on my Garmin Nüvi 250, while what I did follows shortly. Please note that I did not use "remove-short-arcs" before, I added it *because* there were a few of these unconnected roads in this region and I thought that --remove-short-arcs would fix that. Now I'm not so sure anymore ;-)

I'll be happy to test new options and I hope this will help to improve mkgmap (if not, please ignore ;-)

Best regards,

Valentijn Sessink
