A relative was looking for maps of Madeira the other day, and it struck me that
Openstreetmap has infintely better coverage of Madeira than Google maps
(non-existent) or Multimap/Live maps (turning on aerial views shows their
Navteq/AND data to be massively innacurate) Yahoo maps on the other hand has
decent coverage.
It struck me that we could perhaps use Madeira as a showcase for OSM, but
perhaps some further work is needed first. I also noticed that at least some of
the island has reasonable quality high-res Yahoo images. I have started some
*cautious* tracing work on the most obvious roads (I know it's easy to create
hugely innacurate maps by tracing, putting roads where there are none - I've
seen it in OSM first hand :( ) tagging as highway=road. If anyone else cares to
join me, I think we could improve coverage quite rapidly.
The aforementioned relative is soon travelling to Madeira with a GPS, and I
think I can persuade him to bring back a bunch of track files, though I think
they are unlikely to be annotated. It seems showing that OSM can provide better
quality maps than some of the commercial offerings is likely to persuade him to
contribute them.
Now all I need to do is figure out how to make a decent Garmin format OSM map
for him!
Regards,
Dave
