Earth Exploration Toolbook: Measuring Distance and Area in Satellite Images

This chapter describes how to set a scale and measure distances and areas on satellite images. Using ImageJ, a freely available image analysis program that runs on most operating systems, users set the spatial calibration of an image, then select and measure distances and areas on it.

Year of the Solar System Math Guide

This collection of 160 math problems covers the 20 science topic themes presented by the NASA/JPL Year of the Solar System (YOSS) website, covering the solar system, planets, the search for life, and robotics.

NASA eClips™ Real World: CubeSats

Introduce learners to Cubesats - much smaller (1000 cm3) satellites that are being used to gather scientific data and enhance NASA’s space exploration goals.

Building Intuition for In-water Optics and Ocean Color Remote Sensing: Spectrophotometer Activity with littleBits™

This activity demonstrates optical properties of water: that different constituents in water affect the transmission, absorption, and scattering of different colors in the visible light spectrum.

Goldilocks and the Three Planets

Learners will interpret spectral graphs to determine the atmospheric composition of Earth, Venus, and Mars, and then mathematically compare the amount of the greenhouse gas, CO2, on these planets.

Hunting Icebergs: Sizing up Icebergs

This self-paced, interactive tutorial enables learners to identify and measure iceberg size from remotely-sensed satellite images.

Principles in Remote Sensing: Remote Sensors and Data Collection

This self-paced, interactive tutorial provides learners with an opportunity to learn about remote sensors, and the role remote-sensing instruments play in our understanding of the Earth system.

Graphing the Rainbow

Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength.

How When Affects What II: Is it Getting Hot or Not?

Students critically interpret graphical data and evaluate and discuss the difficulties inherent in interpreting and forecasting long and short term trends in this introductory climate change investigation. Graphs of data needed for this exercise are included.

Zooming In

Students examine a series of remotely-sensed images of the US, scaling from the continent to San Francisco, and distinguish the concepts of scale and resolution. At greater resolution, students are able to identify different land classes on the map, using the color key for false color images.
