Question re: satellite imagery sources (lemmy.ca)

When mapping buildings, I'll switch between the ESRI and Bing satellite maps, since they both offer different "freshnes" and clarity, depending on the area.

However, when I use my official municipal or regional websites, they have ESRI maps that appear to be quite a bit newer.

Is the licensing different across different ESRI imagery sources, or could I use the more updated one as a guideline?

EDIT: I think I found my answer from the official OpenStreetMap Wiki:

" Esri is a corporate member of the Foundation."

~~"Esri allowed the usage of Esri World Imagery (and its variants) in OSM mapping, without restrictions and requirements. Even attribution is not legally required."~~

~~This is wonderful news! Having satellite images from only a few months ago, rather than a few years ago, is a game-changer!~~

So this might have been overly optimistic. There may be additional licensing restrictions on variants outside what's available in the OSM editor.

@Showroom7561 you seem to be jumping to conclusions a bit there. Yes we are allowed to use Esri World Imagery in its two variants, there is no permission for anything else.

PS: there have been cases were Imagery was available in the Esri imagery referenced above that wasn't legally available for use to us elsewhere, in the cases that I tracked it 'suddenly' vanished after a while.

in its two variants

Maybe I'm misunderstanding, then. I didn't see it mention "two variants", and we'd only be talking about more recent images of the same satellite imagery.

ESRI does have their own editor for OSM, but I'm not sure if they use the same maps as the stock OSM editor or something else. Maybe I'll give it a try and see if we have access to more.

In either case, I have no plans to actually use my municipalities version for actual mapping (way too tedious, even to try), but it's so interesting to see these very recent images.

@Showroom7561 the two Esri imagery sources are the ones defined here https://github.com/osmlab/editor-layer-index/tree/gh-pages/sources/world
