Hello Andrew,

Sounds like an interesting project you are working on.  Before I
begin, the usual preemptive IANAL and all that. To summarize:

If you use ways that you created from either GPS traces, NPE maps or
landsate, they you can do what you want with them, so long as they
have not been edited by someone else.  You are the copyright holder,
who allows OSMF to use the traces under the terms of the license. I'm
not sure about the Yahoo imagery on this one though - it is provided
to OSMF by Yahoo on the understanding that derivative works are
licensed under the terms if the CC-by-SA.

If your traces have been edited by someone else, you could try to find
out who they are and ask for their permission to use traces they have
edited, or you could use the API's history function to strip out the
changes made.  If your alternative to this is to rectify based on
Google, it comes down to a decision if you think you are more likely
to be sued by Google (or googles imagery providers) for misuse of
their data or by OSM.
