Satellite imagery is an increasingly powerful tool for mapping and visualizing the world. No other method of imagery acquisition encompasses as much area in as little time. The longest-running satellite imagery program is Landsat, a joint initiative between two American government agencies. Its high-quality data appears in many wavelengths across the electromagnetic spectrum, emphasizing features otherwise invisible to the human eye and allowing a wide array of practical applications.
In this lesson, you'll explore Landsat imagery and some of its uses with the Esri Landsat app. You'll first go to the Sundarbans mangrove forest in Bangladesh, where you'll see the forest in color infrared and track vegetation health and land cover. Then, you'll find water in the Taklamakan Desert and discover submerged islands in the Maldives. After using 40 years of stockpiled Landsat imagery to track development of the Suez Canal over time, you'll be ready to explore the world on your own.
