What I did with lake superior is used the canvec data to build the big lake superior object. The multi-polygon become natural=water. then converted the entire line that was the shore to natural=coastline and connect it to the existing coastline out side the object. That way if you import the data into a GPS the lake object for canada shows up, but the is an existing coastline as well (which the US side uses a coastline)<div>

<br>
I have been imported Canvec data around US-QC-ON border and I'm having a<br>
similar question. When should we use Canvec data as is (natural=water) and<br>
when should we transform it into natural=coastline?<br>
<br>
Using natural=coastline on US border (to match tagging with the US portion)<br>
seems fine to me but when do we switch to the other representation?<br>
<br>
Does someone have a proposition?<br>

Subject: Re: [Talk-ca] Update on updating the Lake Huron shoreline<br>
<br>
Hello,<br>
Another update on the conversion of the Great Lakes shoreline plus<br>
one question.<br>
<br>
After something like 10,000 islands, the conversion of the Canadian<br>
shore of Lake Huron (including Georgian Bay) to use the canvec data<br>
is completed! That is a LOT of islands. Given the magnitude of the<br>
task, few changes were made to the land side of things. That's not<br>
quite true as all the islands had all features added - including<br>
Manitoulin Island.<br>
<br>
For the areas that have been rendered it looks much better. It could<br>
be a few weeks before the remainder of the shoreline is updated.<br>
<br>
I have started moving down the St Clair River (connecting Lake Huron<br>
and Lake Erie) and have a question:<br>
<br>
Is there any preferred method to decide where to stop using coastline<br>
and to start using natural=water? There are some channels that cut off<br>
a large part of the mainland in NE Lake St. Clair which could easily<br>
be used as the shoreline. That would be a huge change from the current<br>
shoreline though. Additionally, the route of the current shoreline<br>
would be time consuming to maintain as it would involve cutting up a<br>
number of areas that canvec renders as water. I'd think the best route<br>
would be to use the definition of the shoreline as defined by some<br>
official governmental body, if such a thing exists.<br>
<br>
Any suggestions? Even an answer of 'just do what is convenient' would<br>
be helpful.<br>
<br>
