<p>Long-term remote sensing of North Korea using satellite images has helped overseas researchers build up a profile of the country including food production and military installations.Long-term remote sensing of North Korea using satellite images has helped overseas researchers build up a profile of the country including food production and military installations.</p><p>Red Hat JBoss security software engineer David Jorm, who is studying geography and mathematics at the University of Queensland, recently completed a weather study which focused on the famine that occurred in North Korea during the 1990s.</p><p>"My research was around using satellite data to try and map the impact of the famine. I had a theory that because people would be harvesting crops before they were ready this would result in land degradation," he said.</p><p>"From satellite sensing, you would be able to see that they had a certain level of agricultural productivity and after the famine it was reduced. I did this research and proved that this is what happened."</p><p><a href="http://computerworld.co.nz/news.nsf/security/studying-north-korea-via-satellite">Keep reading...</a></p>
