How can i use OSM Tiles for graphs in a scientific publication

Hello everyone,

I'd like to include a few graphs in my Ph.D. thesis with GPS logs displayed on OSM map tiles. My question is how to correctly deal with the CC licence in this case.

I've had a look at http://www.openstreetmap.org/copyright/en and http://wiki.openstreetmap.org/wiki/Legal_FAQ and from what I've learned, my approach would be as follows:

Include in the label below the graph a text like: "Plot of the GPS data of all driving logs. Displayed on map data from OpenStreetMap available under a creative commons CC BY-SA licence, (c) OpenStreetMap-contributors - see http://openstreetmap.org/copyright and attachment A".

And add an attachment at the end of the thesis with a clarification that all graphs including map data are published under the same CC BY-SA licence + include the Matlab Code for creating the renderings.

I'd deeply appreciate comments on what can be improved or changed.

Clarifications and additional information:

• I'm no native english speaker and the thesis is written in german. So please kindly ignore typos and weird grammar in this post.
• The matlab code I've written basically does this: Take a lot of GPS logs and transform them to the OSM map projection for a certain zoom level. Then locate the corresponding tiles on the hard drive (so it requires downloading those first - I've used JTileDownloader and a small dump of ~2000 tiles), import them into a figure and afterwards add all the GPS plots on top.
• I'd very much like to publish the thesis on a CC-licence which would probably very much simplify the licence attribution for the map graphs, but since many other parties like university and corporate partners need to be involved in this discussion I currently cannot predict the outcome. Issuing a CC-licence for the graphs with map data should be feasible in any case.
