NASA Releases Continuous Images of Planet Earth Saved for 20 Years

NASA has collected nearly two decades of continuous images of the planet and they are accessible to everyone. The record of MODIS space equipment is the longest ever made with satellite imagery of Earth. With it, you can see what the planet was like any day and anywhere on the globe since 2000. In addition, various filters and tools make it easy to see important data and events from the period.

With such a large amount of information gathered, it is even difficult for anyone to know where to start exploring this Worldview tool update. To highlight key moments and how the platform can be used, NASA released this video. In it, we can see the eruption of a volcano, a fire, or the day Hurricane Katrina occurred, as in the image below.

Worldview also offers a variety of filters that can be applied to the image via the "Add Layers" button. Some examples are: Air Quality, Fires, Snow Cover, and Vegetation Types. But perhaps the most fun part is the camera-shaped icon that creates an animation of the passing days at the time of your choice. The result of custom animation can be transformed into a GIF and shared.

The contribution of the tool to researchers is of great value, according to Santiago Gassó, from Morgan State University: “In the 80s and 90s (...) you would take a physical tape with these images and would have to put it in the system. processing. Only then would you know if the image was usable. This process used to take days to weeks. Now you can look at images for days, weeks, and even years in minutes, find the images you need right away, and download them for use. It's fantastic!"
