This episode of Eyes on Earth is the second in a series about how Landsat is helping researchers study coastal changes. The first one was about mapping changes to beaches in California and using Landsat to create models to predict how the coastline may change in the future because of sea level rise and coastal erosion. For this episode, we talk with Robbi Bishop-Taylor, coastal Earth observation scientist at Geoscience Australia, about how he takes advantage of one of Landsat’s best features—time. Using Landsat data back to the 1980s and Open Data Cube to make the dataset openly available, researchers can see where shorelines are eroding and where they are growing around the entire coastline of Australia. Using sub-pixel mapping, they can make Landsat’s 30-meter pixels even more detailed while taking advantage of Landsat’s long archive.
