USA - January 5th, 2012

The bright white area in the upper part of this orthorectified wide-swath ASAR image is Philadelphia, the largest city in the Commonwealth of Pennsylvania. The city is located in the Northeastern United States along the Delaware and Schuylkill rivers. It is the fifth-most-populous city in the United States, with a population of 1,526,006 as of the 2010 U.S. Census.

According to the United States Census Bureau, the city has a total area of 142.6 square miles (369.3 km2), of which 135.1 square miles (349.9 km2) is land and 7.6 square miles (19.7 km2), or 5.29%, is water. Bodies of water include the Delaware and Schuylkill Rivers, and Cobbs, Wissahickon, and Pennypack Creeks. The lowest point is sea level, while the highest point is in Chestnut Hill, at approximately 445 feet (136 m) above sea level (near the intersection of Germantown Avenue and Bethlehem Pike).

Visible to the south of the city is Delaware Bay, a major estuary outlet of the Delaware River on the Northeast seaboard of the United States whose fresh water mixes for many miles with the waters of the Atlantic Ocean. It has an area of 782 square miles. The bay is bordered by the State of New Jersey and the State of Delaware. The shores of the bay are largely composed of salt marshes and mud flats, which appear white in this image, with only small communities inhabiting the shore of the lower bay.

USA - February 10th, 2011

Snow dusts the northeastern United States of America and highlights the ridges of the Appalachian Mountains (upper left). The light color of the snow also makes it easy to spot rivers crossing the landscape, including the Susquehanna River (center) and the Delaware River (right of the former)

In the thumbnail image, parts of New Jersey, Pennsylvania, Delaware and Maryland are snow covered, while Virginia is mostly snow free. The full image stretches northward across New York, Connecticut, Rhode Island and Massachusetts, all of which are blanketed in snow.

Several large cities appear as grey areas near the major waterways of the states of New York, New Jersey and Pennsylvania in northeastern United States of America.

The city of New York can be seen just above the center of the image. The island and borough of Manhattan lies between the Hudson River (left) and the East River (right). West of Manhattan and the Hudson is the city of Newark in the neighboring state of New Jersey.

Further south, the city of Philadelphia is visible on the west banks of the Delaware River, which separates part of New Jersey (east) from Pennsylvania (west).

Bodies of Water Along the East Coast of the USA, from New Jersey to South Carolina

Sediments spill from several rivers along the east coast of the United States, from southern New Jersey (top) down to South Carolina (bottom). These are particularly concentrated around the Charleston Harbor in South Carolina (bottom edge), fed by the Ashley and Cooper Rivers, by the mouths of the Cape Fear and the New Rivers in North Carolina,  and in Pamlico Sound, North Carolina (center).

Just north of the greenish Pamlico Sound is Albemarle Sound, lined with dark brown sediments. The sound is actually a large estuary on the coast of North Carolina located at the confluence of a group of rivers, including the Chowan and the Roanoke.

To the north of the Albermarle Sound, the Chesapeake Bay appears relatively free of sediments. The Potomac River flows into this bay on the shores of the state of Maryland.

Finally, continuing northward, the shores of the Delaware Bay, a major estuary outlet of the Delaware River separating the states of Delaware and New Jersey, are lined with brown sediments.
