USA - February 18th, 2011

The city of New Orleans sits along the shores of Lake Pontchartrain (upper left corner) in Louisiana, USA. Another body of water, Lake Borgne, can be seen to the right.

The Mississippi River passes through the city on its way to the Gulf of Mexico. While the river follows a curved path, a significantly straighter canal can be observed to the right, passing near the shores of Lake Borgne.

This is the Mississippi River – Gulf Outlet Canal, a 76 mi (122 km) channel constructed in the mid-20th century that provided a shorter route between the Gulf of Mexico and New Orleans’ inner harbor Industrial Canal via the Intracoastal Waterway.

New Orleans, Louisiana, USA - February 7th, 2009

The city of New Orleans is located in the Mississippi River Delta in southeastern Louisiana, USA. It was built on the shores of Lake Pontchartrain and the Mississippi River, which runs through the city. A bridge, the Lake Pontchartrain causeway, is visible across the center of the lake.

Lake Pontchartrain is flanked by Lake Maurepas (left) and Lake Borgne (right). Lake Maurepas appears dark brown due to sediments, which are particularly visible towards its southern shore. The other two lakes are more green in color, due to algae growth.

The thick tan-colored bands reaching to the East from the left side of the image are agricultural areas and canals built along the banks of the Mississippi River (above) and along various bayous.

The Mississippi River continues east, through New Orleans, then bends south, and finally southeast. The area where the river meets the Gulf of Mexico is called the Bird’s Foot Delta, the newest section of the evolving Mississippi River Delta.

Here, the main branch of the Mississippi River splits into three different directions at its mouth: Southwest Pass (west), Pass A Loutre (east) and South Pass (centre). The location of this split is known as the Head of Passes.

The waters of the Mississippi River are golden brown from sediments, which are carried eastward and flow into the Bird’s Foot Delta and the Gulf of Mexico. This entire area appears light brown and green, as a mix of sediments and algae is present.

New Orleans, Louisiana - November 29th, 2008

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.
