I've been fine tuning things over the past few days. We have a nicer set of icons although only the volcano icon is currently visible (you need to "Zoom To Arenal"). I've also streamlined some of the OpenLayers code which helps to remove some unnecessary WMS fetches of empty tiles.
The course started earlier today. I gave my presentation on volcanoes (very different from MapPoint). Some of the students have also started to write blog entries. We fly on Sunday, with blog, map, and panoramic photo updates "from the field" through to early June. There will probably be further updates after that - eg. if we have to post-process any data back at base. Student reports will also be published after we come back.
