When you are manually making individual changes, and cross
referencing different sources like you are describing, I don't think the
elements need a source tag. The ideal source for information in OSM is the
contributors themselves, so the best outcome is that you are the source of
the info in the tags, based on your observations of the world (which
includes the satellite, local reporting, and on-the-ground surveys).

A source tag on a feature indicates that the person submitting the changes
hasn't had any input on the information, it is directly from the source.

Instead, I would include the sources in the changeset comment or changeset
tags. That leaves a paper-trail for other mappers to discover if needed
without adding source tags to the map data that would require maintenance.

I hope that reasoning makes sense, and that others here agree!

Cheers,
Ben
