A collection of Landsat 7 scenes created for aesthetic purposes rather than scientific interpretation.

Karman Vortices

Each of these swirling clouds is a result of a meteorological phenomenon known as a Karman vortex. These vortices appeared over Alexander Selkirk Island in the southern Pacific Ocean. Rising precipitously from the surrounding waters, the island's highest point is nearly a mile (1.6 km) above sea level. As wind-driven clouds encounter this obstacle, they flow around it to form these large, spinning eddies.

Iraqi Emplacement

In an area north of the city of Al-Basrah, Iraq, which borders Iran, a former wetland has been drained and walled off. Now littered with minefields and gun emplacements, it is a staging area for military exercises.

Guinea-Bissau

Guinea-Bissau is a small country in West Africa. Complex patterns can be seen in the shallow waters along its coastline, where silt carried by the Geba and other rivers washes out into the Atlantic Ocean.

Great Sandy Scars

In a small corner of the vast Great Sandy Desert in Western Australia, large sand dunes—the only sand in this desert of scrub and rock—appear as lines stretching from left to right. The light-colored fan shapes are scars from wildfires.

Garden City, Kansas

Center pivot irrigation systems created these circular patterns in crop land near Garden City, Kansas. The red circles indicate irrigated crops of healthy vegetation. The light-colored circles represent harvested crops.

Florida Everglades

Spanning the southern tip of the Florida Peninsula and most of Florida Bay, Everglades National Park is the only subtropical preserve in North America. It is the only place in the world where alligators and crocodiles exist side by side.
