Northern Italy

Northern Italy’s Po Valley is the most densely populated area in the country, accounting for nearly half of the national population. In this Sentinel-1A image, acquired on 24 April 2014, cities are visible along the bottom as bright radar reflections, lined along the main highway running left to right. Milan appears brightest on the left. Lake Garda, in the upper right, is Italy’s largest lake and third largest in the Alpine region.
