For larger landmasses the coastline is defined as a series of linear ways connected end to end. These ways <b>must create a continuous interlinked coastline</b>, the end node of one way must be the start node of the next way. A break in the coastline or other error can cause serious difficulties when using this data.

They <b>must</b> be drawn so that the <b>land is on the left side and water on the right side</b> of the way (when viewing in the direction of the way arrows).
