The Hindu : Sci-Tech / Internet : New crater in Sudan discovered using Google Maps


"Software scientists have discovered a 10 kilometre wide crater like structure in the Bayuda Desert of Sudan using Google Maps...
Amelia Sparavigna from the Politecnico di Torino in Italy said she got the idea from Italian researcher Vincenzo de Micheles who identified an impact crater in the remote desert of southern Egypt by 2008 using Google Earth. Located between the fourth and sixth cataract, the area is characterised by basaltic rocks from ancient volcanoes. Sparavigna noticed “a non-perfect round shape about 40 kilometres in diameter” on the eastern bank of river Nile. She then processed the original Google Maps satellite image with an astronomical image-processing program. “Aerial photography is expensive and satellite imagery doesn’t always have good enough resolution. But in this case they have been able to generate some interesting images which have been further enhanced,” ABC Science quoted Professor David Cohen, a geologist, as saying."
