This image is a compilation of three radar images from the Japanese ALOS satellite and shows the Po River, which flows over 650 km from west to east across northern Italy as the country’s longest river. Agriculture is one of the main economic uses of the Po Basin because of the fertile soils, and this image clearly shows a landscape dominated by fields. Branching off of the river in the center of the image and snaking through the landscape to the lower-right corner is the Po di Goro, one of the main channels of the Po Delta. The section of the main river pictured and the Po di Goro form the border of the Italy’s Veneto (north) and Emilia–Romagna (south) regions.
