Dikes and Levees by Coast of Netherlands – March 11th, 201252.3N 4.8E
The bright white parts of this wide-swath ASAR image show the most heavily populated areas of the Netherlands. The country is among the most densely populated on earth: ranked 15th overall. The country’s geography is unusual in that much of its land has been reclaimed from the sea and is below sea level, protected by dikes.
The Netherlands can be split into two areas: the low and flat lands in the west and north. These lands, including the reclaimed polders and river deltas, make up about half of its surface area. An extensive range of seawalls and coastal dunes protect the Netherlands from the sea, and levees and dikes along the rivers protect against river flooding. Such levees and dikes can be observed in the full image, near the coast, appearing as thin grey lines crossing the bodies of water.
