Generally some of the polygons can be later merged across the boundaries
into less square shapes, but it can be complicated and slow work.
Personally, I'm still unclear on whether CanVec importing is still going
on? Is the data still available and updated? Most of what I can find on the
wiki is
Forest footprints change over time but not that much in most places. The
problem is that forest polygons can quickly end up with thousands of points and
have the added complexity of holes.
There is value to having them in OSM, we just have to find a better way to do
them, or live with "seams"

Or, dare I suggest, deleted completely. If they take a huge amount of
work to fix and they add little value by being based on elderly data, I

Yeah forests are not an easy task to handle, I've been trying to tackle
this from time to time in rural areas as to no put a forest in the city,
but it's a long process as you need to validate a lot of things before you
can upload a small portion of land.
I've tackled a few today:
Alan is right. I've brought in a few tiles worth of forests from Canvec in
the area you're talking about, but they were non-trivial to deal with
compared to most other features. I kept running into limits in the tools I
was using at the time and I haven't returned to them since.

Bon points Jean-Denis,
Les descriptions techniques aident souvent. Dans les cas où j’ai utilisé cette
source de données, elle référait souvent aux lotissements mais la carte des
lotissements (matrice graphique) ne peut être utilisée dans OSM (licences).

Bonjour Antoine,
Pour la limite des parcs, les descriptions techniques des délimitations
font partie des règlements sur l’établissement des parcs nationaux [1]. Il
y a là des repères susceptibles d'aider à leur cartographie.
Une autre alternative consisterait à transmettre une demande au
Bonjour Antoine,
Pour ajouter aux commentaires d'Alan et d'Adam.
Pour ce qui est de la forêt...
Comparer la forêt US/Canada est un peu injuste. En général, la forêt n'est pas
cartographiée du côté US, et elle a été partiellement importée du côté canadien

Hello all
First, sorry for writing in English, my french is not so good.
While trying to add missing roads in osm that we have detected,
i found a lot of areas where you cannot find either hires images or you find
images that are to old to see the new road that was created.
I know that Martijn
Both of your instincts on the matter are correct - these polygons are the
result of CANVEC data imports and has to do with how that data is packaged
for distribution by Natural Resources. If you go to the CANVEC site, click
on the map, and zoom to an address, you eventually get to the level where
10 matches
