[Talk-ca] Update on updating the Lake Huron shoreline

[Daniel Begin]

Hi all,

I have been imported Canvec data around US-QC-ON border and I'm having a
similar question.  When should we use Canvec data as is (natural=water) and
when should we transform it into natural=coastline?

Using natural=coastline on US border (to match tagging with the US portion)
seems fine to me but when do we switch to the other representation?

Does someone have a proposition?

Daniel

Hello,
Another update on the conversion of the Great Lakes shoreline plus
one question.

After something like 10,000 islands, the conversion of the Canadian
shore of Lake Huron (including Georgian Bay) to use the canvec data
is completed! That is a LOT of islands. Given the magnitude of the
task, few changes were made to the land side of things. That's not
quite true as all the islands had all features added - including
Manitoulin Island.

For the areas that have been rendered it looks much better. It could
be a few weeks before the remainder of the shoreline is updated.

I have started moving down the St Clair River (connecting Lake Huron
and Lake Erie) and have a question:

Is there any preferred method to decide where to stop using coastline
and to start using natural=water? There are some channels that cut off
a large part of the mainland in NE Lake St. Clair which could easily
be used as the shoreline. That would be a huge change from the current
shoreline though. Additionally, the route of the current shoreline
would be time consuming to maintain as it would involve cutting up a
number of areas that canvec renders as water. I'd think the best route
would be to use the definition of the shoreline as defined by some
official governmental body, if such a thing exists.

Any suggestions? Even an answer of 'just do what is convenient' would
be helpful.
