Landsat 8 Swath Animation

Summary

Landsat 8 orbits the sun in a sun-synchronous orbit, capturing images of the Earth every 99 minutes, about 14 times a day. As it moves from the north pole to the south, it covers a 115-mile wide 'swath,' providing a daily snapshot of the planet. Over 16 days, Landsat creates a complete picture of global changes, continuously monitoring the Earth's environment. This cycle of observation helps track and document changes on the planet in real time.

Q & A

What type of orbit does Landsat 8 use?

Landsat 8 uses a sun-synchronous orbit, which allows it to capture imagery in direct sunlight consistently.

How often does Landsat 8 complete one orbit around the Earth?

Landsat 8 completes one orbit around the Earth every 99 minutes.

How many orbits does Landsat 8 complete per day?

Landsat 8 completes approximately 14 orbits per day.

What is the width of the area covered by Landsat 8 in each pass?

Landsat 8 captures data over a 115-mile-wide 'swath' during each orbit.

How many swaths does Landsat 8 add to the dataset every day?

Landsat 8 adds 14 swaths to the dataset every day.

What does Landsat 8 achieve over the course of 16 days?

Over 16 days, Landsat 8 captures enough data to complete a full picture of the planet.

What happens after Landsat 8 completes a full 16-day cycle?

Once Landsat 8 completes a full 16-day cycle, it begins the cycle again to monitor global changes continuously.

Why is it important for Landsat 8 to have a sun-synchronous orbit?

A sun-synchronous orbit ensures that Landsat 8 always captures images under consistent lighting conditions, which is important for accurate comparison of data over time.

How does Landsat 8 contribute to monitoring global changes?

Landsat 8 provides daily updates through its 14 orbits and 115-mile-wide swaths, offering valuable data for tracking changes on the planet’s surface, such as deforestation, urbanization, and climate changes.

How does the swath width of Landsat 8 contribute to its effectiveness?

The 115-mile-wide swath allows Landsat 8 to cover a large area of the Earth’s surface in each pass, making it efficient for monitoring wide-scale global changes.
