Right, but the issue is the Share Alike part: "If you alter, transform, or build upon this work, you may distribute the resulting work only under the same or similar license to this one." Does this refer to just the figure? Must the thesis as a whole be Share Alike?? Would it be possible to use Esri content in a figure to be published in a peer-reviewed journal?
Alternatively, is there a way to purchase Esri content for such use?
