Satellite Imagery

satellite earthThe theme for May 2016 is Satellite Imagery. We picked out 10 articles, with topics ranging from satellite radar interferometry to measuring spatial developments. Several Earth Observation satellite constellations are highlighted, including the SPOT family and the Sentinel programme. In addition, various exciting applications of satellite imagery – for example the support of polio eradication and tracking urban change and flood risk – are covered.
