Building on my post from the 27 February, it seems that 2014 certainly is a year where remote sensing is hitting the mainstream. The reasons for this may not be happy ones (floods, missing aircraft, landslides) but the use of satellite imagery (and satellite technologies in general e.g. the signal processing and modelling undertaken by … Continue reading Remote sensing: efficiently searching the seas →

Quite a few people seem puzzled when I tell them that my job involves remote sensing. It seems that remotely sensed imagery is becoming ever more present, with it being used across the news media and embedded into online maps, but very few people know that there is so much more to it.
