USA and Mexico - June 2nd, 2009

Agriculture, mountains, desert and populated areas are all visible in this radar image of the USA-Mexico border.

The bright white area in the lower left quadrant is San Luis Río Colorado, a city and its surrounding municipality lying in the northwestern corner of the state of Sonora, Mexico. The municipality covers an area of 8,412.75 km² (3,248.2 sq mi) in the Sonoran Desert.

The city is situated on the banks of the Río Colorado, which at this point marks the state border with Baja California. It also stands on the international border with the United States, adjacent to San Luis, Arizona.

Reaching in diagonally from the center left is the southeastern end of a large erg, or sand dune field, called the Algodones Dunes.

Also stretching diagonally across the image, through its center, is a mountain range in the Sonoran Desert. It crosses from California into Arizona, before finally reaching Mexico.

Mexico-USA border - December 9th, 2008

The border between the Mexican state of Baja California and the state of California, USA, runs through the center of this radar (ASAR) image.

On the left, the city of Mexicali, Mexico, appears bright white. Just above is its sister city, Calexico, California. The border appears as a line, between the two cities, accentuated by the difference in organisation and color (intensity of grey) of the crops near them.

The line continuing eastward from the Mexicali area is actually not the border, but rather the US Highway 8 running just north of it.

On the Mexican side of the border, on the bottom left, part of the Sierra Madre Occidental mountain range can be seen in light grey and white.

On the USA side, the dark area is a patch of desert. The diagonal line through it is the Algodones Dunes, a large erg (sand dune field). It is approximately 72 kilometers long by 10 kilometers wide (45 miles by 6 miles) and extends along a northwest-southeast line that correlates to the prevailing northerly and westerly wind directions.
