+1 Even if the trail did exactly follow the pipeline one should create
a separate way. Otherwise you'll get into trouble with the multiple
tags, especially level=* One could also use relations but that would
be overkill and prone to error.

[Talk-ca] Oil Pipeline?

2012-06-26 Thread Steve Roy

Hi all,

I am mapping around Lac Le Jeune in BC and a part of the area where we 
snowmobile in the winter is along the pipeline.

An example of the area in question is:
http://www.openstreetmap.org/?lat=50.47171lon=-120.37725zoom=15layers=M

On the map it doesn't show the pipeline (probably because it's layer is 
-1), however if you do an edit on the area it will show the pipeline.
What's the best way to be able to show there is a trail where the 
pipeline is?  Can I just add a highway/trail on top of the existing 
pipeline? Or?


Thanks

Steve (SRW)

The pipeline shows up when you hit edit because the pipeline is in the
database. You're just looking at a map rendering that doesn't display
pipelines underground. I don't know of one that does personally, but
it would be easy to create one. There's a lot of stuff in the database
that doesn't get rendered on the default Mapnik map style.
