This activity of the Earth Exploration Toolbook walks users through a technique for documenting change in before-and-after sets of satellite images. The technique can be used for any set of time-series images that are spatially registered to show the exact same area at the same scale. In the chapter, users examine three Landsat images of the Pearl River delta in southeastern China. In the images, ... Full description.

Users download and analyze MODIS imagery from 2001 and 2003 to quantify the shrinking of the Aral Sea. The chapter steps users through downloading, installing, and measuring with ImageJ, a freely available image analysis program. Users employ the software to set the spatial calibration of an image, then select and measure distances directly from the image. Measurement results are reported in real-world ... Full description.

Users download and analyze satellite images showing the amount of ozone in the stratosphere. They interpret the images to identify the ozone "hole" that develops over Antarctica each summer, and compare its size from year to year. Using freely available image analysis software, ImageJ, users quantify the area of the Antarctic ozone hole each October from 1996 to 2004. Finally, they bring their measurements ...
