so on the question ...

Is it possible to vectorize the USGS on the OSM if there is no Landsat, and
everything else in the clouds, or in the snow, or the quality is bad ...

Hello velmyshanovnyi , There are a number of questions here. One is "is it
possible to vectorize the USGS". Another is "is it a good idea to do so".

I'd suggest that you discuss what is the best source of imagery in this
region with other mappers, such as "imagico" who commented on
https://www.openstreetmap.org/changeset/52947504 . It may be that you need
to use several sources and combine them manually because none of them are
perfect. Also I would suggest asking on the talk-us and talk-ca mailing
lists for advice.

With regard to "is this a good idea" other mappers think it is not. You
need to persuade them that it is. You need to explain what your process is.
Your comment on https://www.openstreetmap.org/changeset/52947504 that says
"Im fixed my soft" suggests that you might be performing some kind of
mechanical edit. If so, you need to follow
https://wiki.openstreetmap.org/wiki/Mechanical_Edit_Policy , which requires
you to discuss what you are proposing to do with other mappers before
actually doing it.

Best Regards,

Andy Townsend, on behalf of OSM's Data Working Group.
