手順

  • Pass 1: 主要な道路のマージと道路中心の位置修正 (motorway-secondary); 合流ラインや正確な一方通行情報、主要な高速道路の上り下り車道分離を行います。 Realinear y fusionar las vías principales (motorway-secondary); Crear doble vías en las rutas principales con carreteras enlaces y corregir los sentidos.
  • Use inverse filter. Usar filtro inverso. highway=motorway|trunk|primary|secondary|*link|motorway_link
  • Pass 2: 道路(tertiary)のマージと道路中心の位置修正; Adding missing tertiary+ highways and link roads; Adding missing bridges/tunnels on tertiary+ highways; Alinear, fusionar y agregar vías terciaria; Agregar vías de enlace y puentes/ túneles en las vías terciarias ;

属性(タギング)

  • Delete the imported yh:WIDTH tag if required to help combining ways
  • Do not reclassify existing roads unless there is a good reason to do so
  • Japan drives on the left hand side of the road, make sure the oneways are in the correct direction.
