Bonjour Dega,
En effet toutes les clairières devraient être taguées en consequence par un
polygone. Un tag approprié pour cela pourrait être meadow ou scrub.
Quand à la présence ou non d'un sentier... difficile à dire par la vue
satelite: il faut vraiment un reperage terrain par des
Hello Dega / all,
With regard to a path that cuts through a forest, the initial thought might
be to map the path as dirt or something similar. However, this would not be
efficient nor required. A line that denotes a path is, in itself,
technically a type of land tag as the any such pathway must

Hello,
Yes indeed some European countries are going further into smaller details.
And it's legit.
However, in the Canadian context, it seems that adjust fix massive CanVec
data imports has higher priority than touching up every single landuse

It's not only about woodlands water, but
Bonjour Bruno
Je suis d'accord avec la logique de Frank : redécouper les polygones de
CanVec selon les lignes de frontiéres naturelles (rivières, lacs...) et
artificielles (routes, lignes électriques, lignes coupe-feu...etc..).
J'ai regardé tes exemples. C'est un compromis intéressant. La zone
Plusieurs (et j'en suis) ont exprimé leur désir d'avoir une meilleure
couverture de forêt sur la carte OSM. Ces zones de forêt sont venues avec les
importations CanVec mais ne progressent plus depuis un certain temps. Le
présent article propose une façon de réaliser la forêt sans utiliser les abus
Hi Dega,
Sorry, you can't just get away with not creating holes for lakes,
clearings, etc. What if you get an extract of OSM, and you're only
interested in the forests, because you want to calculate the percentage
of forest coverage. You don't get information about lakes, heath and
other
Salut Frank, long time no see
... What if you get an extract of OSM, and you're only

of forest coverage. You don't get information about lakes, heath and
other land uses when you don't cut out holes from multipolygons.
