[mkgmap-dev] [PATCH v1] Merge road network

Wed Aug 28 00:56:01 BST 2013

Hi,

does roads have to have the same post code? I don't know internal 
representation of these data, but in mp sources single road can have 
parts with different post code or city/region.

Do you check angle at which roads are merged?

Imagine a two-way road, which splits into 2 one-way roads before a 
crossroad. You can get this one-way roads merged. I don't know if this 
would be a problem for routing, but a weird layout anyway.

Or you can get a crossroad where roads can be merged in many 
configurations. In that case I would prefer to get straight roads after 
merging.

If you merge two roads, that form a turn at a crossover, there could be 
missing announcement from navigation. This probably depends on angle, 
but I'm not sure about details. Again, I prefer to merge only roads that 
goes nearly straight.
