This app allows you to navigate the world with Landsat satellite imagery. Landsat takes images of the planet to reveal its secrets, from volcanic activity to urban sprawl.
Landsat sees things on the electromagnetic spectrum, including what's invisible to the human eye. Different spectral bands yield insight about our precious and continually changing earth.
Over the past 43 years, Landsat has amassed over a petabyte of data, with over 4 million scenes and counting. It takes images of every location on earth every 16 days. You can explore historic images to see how places change over time.
In this app, use the symbols to try different spectral views. Some are combinations of bands and others computed indices. ArcGIS automatically enhances the image based on your current view, so try zooming and panning.
Use the time slider to see how places change over time. For more details on any location, click identify, and then click on the map.
