How to Map

ElementWay.png

To map a canal make a simple way. Add the waterway=canal tag to it. You should also add a name with name=* if it's known.

Note: A canal way is direction dependant. Draw the way segment into flow direction.

Additional Tags

Use width=* to indicate the width in meters. This is an average width of the canal along the length of that portion of canal. You can use width=5 to tag an average canal width of 5 meters.

Generalised Way type tags

Outlines

Wide canals can have drawn outlines. To draw the outline create an Area Area with the tags:

The Area can be created as closed way or with a Multipolygon with the tag:

Note: older canal areas might still use the tag waterway=riverbank.

A central way tagged with waterway=canal is still needed.
