How good is your geography? Can you name the locations of the above images?
Here are some clues:
Two of the images are of cities in the US, one of them on the West Coast and the other on the Gulf of Mexico.
Another image is of a city in western Canada.
The fourth image is of a well-known coastal area in the US.
Click on the images to get an enlargement and description.
The images were taken from the space shuttle with NASA's imaging radar instrument, the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR). The SIR-C/X-SAR instrument is a joint US-German-Italian project.
More Cool Stuff
- The above images and some of the text come from "Radar Images of Earth," a Web site of NASA's Jet Propulsion Laboratory (JPL) that features radar images of cities around the world, oceans, rivers, snow-covered areas, volcanoes, and more:
