Dear Carolyne,
Are you asking to organise another session next Friday? We have Crowdsourcing as a theme that week, I will record a lecture. We can have a discussion around your presentation if you use this topic.
The assessments are on the Moodle page, at the top.
You can do something on Crowdsourcing - linking it to Big Data. The crowd mapping, donation of satellite images is a good topic. You can look at how it is organised, the motivation to participate, who donates the images, the actual use of the maps/data on the ground, why the maps are need (i.e. are their existing maps but closed).
