[OSM-talk] Canals, drains etc

[James Stewart]

We seem to have some gaps, and variety of practice in mapping Canals,  
irrigation canals, drains etc. Maybe this is a good topic for  
Amsterdam with some on the ground observation. The small water  
channels in the Netherlands are mapped as drains, which seems OK.  
Canals however are mapped as lakes!

Long irrigation canals (that are sometimes called the X Canal, but in  
the UK examples on wiki are called Drains ) are rendered too wide, but  
somehow drain does not seem right. Should we make a distinction   
between transport canal and irrigation canal?  In mapping the Fergana  
valley I have used 'canal' for the thousands of irrigation canals.

What do other people use?
