New Orleans, Louisiana
New Orleans is a major United States port city and the largest city in the U.S. state of Louisiana. It is located in southeastern Louisiana, straddling the Mississippi River, the curving black line moving downward through the image. The two straight perpendicular black lines are man-made canals.
The city is located in the Mississippi River Delta on the east and west banks of the Mississippi River and south of Lake Pontchartrain, visible in the upper part of the image. A bridge, the long Lake Pontchartrain Causeway, can be seen across the lake. Another lake, Lake Borgne, is visible to the right.
According to the United States Census Bureau, the city has a total area of 350.2 square miles (907 km2), of which 180.56 square miles (467.6 km2), or 51.55%, is land.
The area along the river is characterized by ridges and hollows, clearly visible in the image, particularly in the southern area. Countless bays and lakes are present.
New Orleans was originally settled on the natural levees or high ground along the Mississippi River. After the Flood Control Act of 1965, the US Army Corps built floodwalls and man-made levees around a much larger geographic footprint that included previous marshland and swamp.
