 Well, I'm currently working on this really exciting project in Antarctica, where we're flying drones over several locations and we're mapping an area to try and understand the human footprint or how we as people have impacted on this really fragile ecosystem. So what we do is we take these drones and we fly, we launch them in the sky, they're big aircraft, they're about three meters wingspan and they go up in the air with really special sensors or cameras on them and they just basically mow the lawn so they go back and forth and back and forth and we create this big mosaic made out of thousands of photographs or images and from those I stitch them all together and we can create a 3D landscape and look at how have people made footprints. What are these footprints? What have they left behind? We're interested in this because parts of Antarctica will be opened in this raw sea dependency area, will be opened for tourism visitation and there's areas already zoned for tourism visitation but what we want to know is before all those tourists arrive what is the baseline, what is the landscape like, what impact is there now and how can we map that and understand that.
