Module 1: Eyes on Satellite Data
An Image-Based Approach
Week 1: From the Outside Looking In Changing Our Perspective of Earth
This first week of the course is an introduction to remote sensing and its value for understanding Earth and how it changes over time. You will browse a variety of images and animations created from remote sensed data, explore Earth from the perspective of a NASA satellite using the Eyes on the Earth 3-D simulation, and use NASA NEO to download a satellite image that you can use in your teaching.
Begins on January 29, 2010
Week 2: Analyzing Change Over Time
Without tools designed to measure and analyze remote sensing images, they are often just pretty pictures. We may get a qualitative sense of what's going on, but science requires a quantitative analysis as well. In Week 2, you will be introduced to ImageJ, a public domain image processing program developed by scientists for scientific analysis. You will use some of the tool's basic functions to analyze the impact of drought on Lake Mead.

Week 3: Eyes on the Ice
Among the issues related to global climate change are the effects of the thickness and extent of polar sea ice as a habitat for animals in polar regions, as well as the implications to people living in or near these regions. In Week 3, you will learn to create and manipulate image stacks in ImageJ to visualize and analyze changes in the extent of Arctic sea ice over time.

Week 4: Using Satellite Data to Study the Ocean
In Week 4, you will learn how to use NASA's web-based tool, Giovanni, to access, visualize, and analyze ocean color remote sensing data. You will create a time-averaged data map and a time series animation of chlorophyll-a data from Chesapeake Bay.
