Hi, Everyone, I am pretty new to this treasure island, got two questions in the osm file format 1. A road is split into several xml element (tagged "way"), how to merge them into one piece? Is there a relation element include all the road pieces into one road? If I want to calculate the length of a road, I can get all these pieces and sum them up, but I don’t particularly like this approach. Because you lost the order information (which piece is connected to another) 2. Is there a node type/data for road intersection? Thanks Shawn
