Option to delete unconnected ways?
Hi, Is there an option to pass to mkgmap that would delete unconnected ways? Those unconnected ways lead to routing errors and are useless in a generated map. Francisco

Wouldn't it be better to throw a warning rather than deleting them? This way they could be fixed in the osm data. Apart from that, they can be of interest in non routable maps.
how will mkgmap decide wether ways are unconnected by mistake or by intention? a warning would therefore be much better. Am 14.11.2011 16:42, schrieb Carlos Dávila:

I am not asking to do this by default, but to have an option where I can delete routable ways that are disconnected. Those cause routing errors if left in the map and it is not always easy to fix them. For example, trails in a wooded forest. Is there another trail that leads to them or not? Easy to fix if you know the area but not so easy if you are relying on satellite photos. Just my 2 cents. Francisco
it has been discussed in a similar form earlier. it's useless and creates more problems than it solves - islands have roads not connected to the rest, and yes sometimes we have bridges or ferry lines, but some are accessible by plane only or private boat lines only - garmin maps are tile based. and many routable lines are not connected within a tile but connected to the next tile. mkgmap can't know what to keep. a map generated with such an option will be completely broken. The only chance would be to take a whole planet, create a routing graph and filter out by some heuristics to make sure islands are not pruned. On Nov 15, 2011, at 8:20 AM, Francisco Moraes wrote:
