Mentioning courses taken on coursera.org in the statement of purpose

Is it of any value to mention a course one is following on www.coursera.org, in a SOP?

For instance, if I have a Bachelor of Computer Science and want to apply for a Geoinformatics Master program, would it help my application at all to mention that I am currently following a Geoinformatics course on coursera.org to get familiar with the field?
