Seeing Temperatures

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...

What Can We See From Space?

This short activity introduces students to the ideas of the footprint and resolution of an image, asking them to choose and use appropriate methods to calculate how these quantities would change as they moved a camera to a series of vantage points above the surface of the Earth

Where Would You Photograph? (14-16)

In this activity students take on the role of Earth observation scientists submitting a request for an image they would like for their research. This gives them the opportunity to consider the possibilities of pictures taken from orbit (and the limitations) and to write scientifically for a specific audience. It...
