Re: [Libosmscout-development] Cannot get TYPE wood to render above level 10

Next round of investigation...

When I disable low zoom optimization, highways (highway_motorway) 
are displayed. It seems that highway_trunk exists in my waysopt.dat 
but highway_motorway are not there!

But it should be there, in import log are these lines:

Tim, howto continue? 
How can I check that highways exists in wayopts.dat? 
If these ways are there, why are not loaded by MapService::GetWaysLowZoom ?
