</font><font size="-1">When I use high-resolution imagery to improve
areas formerly mapped from low-resolution imagery, I change the
source tag on the objects I touch - i.e. from "Yahoo low
resolution satellite" to "Microsoft Bing satellite". Since my edit
is correlated with a change of source, can it still be considered
as a tainted derivative ?<br>
<br>
Modifying a way </font><font size="-1">mapped from low-resolution
imagery to take advantage of high-resolution imagery changes it so
much that the result barely takes advantage of the previous
version. It does take advantage of the fact that the object
exists, which makes the work somewhat easier (except maybe in
dense areas where it can even make it more complicated) - is that
enough to make it a derivative work unable to be migrated under
the new license ? That improvement process is rather close to a
remapping... Or should I just remap ?</font><br>
