[Talk-ca] Coastal water - Canvec

[Bégin, Daniel]

Bonjour Lennard,

Few months ago there was a discussion on Talk-CA list about the availability of intermittent coastal water representation in mapnik.  

Now that the Canvec product (http://wiki.openstreetmap.org/wiki/CanVec) has been made available, there is going to be a lot of intermittent water (http://wiki.openstreetmap.org/wiki/CanVec:_Hydrography_(HD)) uploaded in osm database.

As you proposed, I've done the following...

1.) open a trac ticket with component=mapnik 
Ticket #3188

2.) include one or two link to places where it is used 
http://www.openstreetmap.org/?lat=50.2095&lon=-66.3944&zoom=12&layers=M : a large coastal bay with intermittent water (could have been tag water=tidal;surface=grass instead of just water=intermittent)
http://www.openstreetmap.org/?lat=50.1256&lon=-66.6402&zoom=14&layers=M : a long beach along a coastal intermittent water area (the coastline splitting landform=beach and water=intermittent areas, both having surface=sand).

Don't hesitate to contact me to get further explanations

Cheers,

Daniel

Points 4,5,6 are mostly for osmarender.

> Point 6 is less obvious.  I've had a look at the mapnik wiki and did not get the answer I was looking for.  Do you have an example of a patch that could do the jobs?

I have a personal interest in these coastal features, so I'd say do only points 1 and 2 for mapnik. We'll get it from there.
