Disappearing Sea

Challenge using Satellite Images of the Aral Sea.

Analyze the images below to calculate the rate the Aral Sea is disappearing.

Download the satellite images below and use the "Area" tool in the AnalyzingDigitalImages software.

To download the image, either right-click or click and hold on the image. A pop-up menu will have the option to 'Save Image As...', which allows you to save the image on your computer.

You may do this to download most images available on the Internet.

See the Manual and Help Files on AnalyzingDigitalImages for guidance. AnalyzingDigitalImages is available in the DEW software bundle.
