Hi!

I don't see any difference between merging externally generated contour

the resulting IMG file looks the same.
The difference is what is being published: You may not create a map from
both sources and redistribute it. But you may distribute each layer
seperately and let the end user combine them into a map, which he may
not redistribute.
And I don't agree that this would be a derived work. OSM does not
contain any DEM data or contour lines, so by adding them the OSM layer
remains unchanged and clearly discernible from the contour lines, so I
would say the result is a collective work.
Discernible is not enough. You need to read through the full legalese. A
collective work is defined as a collection of unmodified entities. This
is definitely not true for a gmapsupp.img.
Took me a while to understand and believe how bad the current OSM
licence is, too.
