Using Landsat to Spot Changes in Land Use | NASA Space Earth Science Video
Learn how Landsat data are used to detect changes in land use. This video describes how the data are interpreted and gives examples of changes in forests from different insects and differences due to land management.
Global Land Use for Years 1900 and 2100
Examine data to evaluate the primary land cover in 1900 versus the projected primary land cover in 2100. Discuss the implications of the differences.
Energy and Matter: Dust Crossing (2015)
The Sahara Desert is a near-uninterrupted brown band of sand and scrub across the northern third of Africa. The Amazon rain forest is a dense green mass of humid jungle that covers northeast South America.
Creating and Interpreting Images
Information from satellites if often used to display information about objects. This information can include how things appear, as well as their contents. Explore how pixel data sequences can be used to create an image and interpret it.
Creating Images from Numbers
Grade Level: 3-5, 6-8, 9-12
Scientific data are often represented by assigning ranges of numbers to specific colors. The colors are then used to make an images which allow us to see patterns more easily. Students will make a false color image using a set of numbers.
