I have spent some time trying to figure out an appropriate license. If I 
understand these licenses correctly, I am free to choose the license for 
the combined work (my GPS map), and I can chose it to be NC and SA. OSM 
data are only a small part of the effort. As far as I can tell, the ODBL 
gives me freedom to license the final product under licenses like 
CC-BY-NC-SA. Anyone wishing to use the OSM data themselves can just 
download them for themselves; I have not applied any modifications 
(created an adaptation) to the data - I'm only putting a layer on top.

The CTRN is CC-BY and therefore should grant me the same freedom of 
choice of license, as it's not SA. I have discussed the license issues, 
and I was advised to use CC-BY-NC-SA, because, in theory, it can hinder 
people who just download my map and then try and sell it to people who 
aren't clever enough to put 'GPS CTRN OSM' into a google search.

Nevertheless I am open to suggestions. Are you implying my choice of 
license is illegal? Or is it just that you don't like it? The main work 
in creating the map was converting the data to a joint format and 
writing styles to display the data on the GPS unit (like, drawing icons 
etc.), and I think I am entitled to use the license I've chosen.

Let me quote from the ODBL, since you say my map is 'not compatible' 
with it, and comment on it:


    *As long as you:*

  * /Attribute:/ You must attribute any public use of the database, or
    works produced from the database, in the manner specified in the
    ODbL. For any use or redistribution of the database, or works
    produced from it, you must make clear to others the license of the
    database and keep intact any notices on the original database

- I attribute by displaying the standard OSM attribution link on the 
splash screen of the GPS davice on loading the map. Generally this is 
deemed acceptable and the done thing.

  * /Share-Alike:/ If you publicly use any adapted version of this
    database, or works produced from an adapted database, you must also
    offer that adapted database under the ODbL.

- I have not adapted the data; I have only used the data. AFAICT this 
does not count as an adaptation. I think my work is a 'combined work', 
or a 'Collective Database'. This is defined thusly in the full legal 
text of the ODBL:

"Collective Database" -- Means this Database in unmodified form as part 
of a collection of independent databases in themselves that together are 
assembled into a collective whole. A work that constitutes a Collective 
Database will not be considered a Derivative Database.

Further down it says:

4.5 Limits of Share Alike. The requirements of Section 4.4 do not apply 
in the following:

       a. For the avoidance of doubt, You are not required to license 
Collective Databases under this License if You incorporate this Database 
or a Derivative Database in the collection, but this License still 
applies to this Database or a Derivative Database as a part of the 
Collective Database;

If anyone splits my map to use the OSM tiles themselves (which are 
pretty useless outside the context of the styles and TYP I use in my 
map) they are free to do so, and the README clearly states what license 
the components are under.

  * /Keep open:/ If you redistribute the database, or an adapted version
    of it, then you may use technological measures that restrict the
    work (such as DRM) as long as you also redistribute a version
    without such measures.

- Same here. Since I'm not using an adaptation but a derivative work, 
using CC-BY-NC-SA on the final product should be correct.

OSM is improved by contribution of data. To gather these data in the 
field, precise GPS maps are a great help. The GPS map creation tools 
were essential to get the project off the ground, so that FIX-ME data 
etc. could be seen on the GPS device. By offering an OSM layer on top of 
the CTRN I am helping the community to map more efficiently (At least I 
hope so). I can't see your point. Anyone can load and use the map, for 
free. What they do with it is up to them, as long as they don't violate 
the license. It doesn't get much more liberal than that. What do you 
think would be a 'good' license for a GPS map?

I hope I have been able to clarify why I have licensed the map as I 
have. Thank you for your encouragement. I am not a lawyer, and the whole 
licensing issue is, to me, a waste of time. Nevertheless, to allow the 
community to share my work (rather than just enjoying it myself), and to 
do this in a legally proper fashion, I had to spend days researching and 
corresponding and creating my own styles (rather than using ready-made 
ones, which would have introduced yet more licensing issues) to satisfy 
all the license requirements. If my understanding of the legal matters 
is wrong, please point out specifically where you see conflicts.

The ODBL should have made my work simpler, and when I read through it 
carefully I found that there are some subtle changes in the treatment of 
derived works (compared to the previous license) which give me more 
freedom in licensing the final product than the previous license.

Thank you for the invitation! But I won't be able to attend, as I'm not 
in Italy at all. With a bit of luck, my map will have been used by some 
of the community and they may discuss it and spread the word even if I'm 
not there.
