News hardware Google has a different mapping system than Maps and you don’t know about it

Dynamic World is a powerful satellite imagery tool that Google saves for scientists and professionals. It displays soil conditions around the world with an accuracy of 10 meters.

If Google Maps is a mapping system that serves travelers all over the world, Dynamic World, meanwhile, A very different goal. This tool was developed by Mountain View Firm Offers a real-time display of land use across the planet.

Designed in partnership with WRI (World Resources Institute)Launched Dynamic World-Based, such as Google Maps Google Earth Engine. This is added A powerful machine learning technology, AI platformWhich is responsible for cross-checking the data provided daily by a satellite for a land use project on a map With an order accuracy of 10 meters.

What is Dynamic World for?

Inside A blog post Published June 9 and named “Land cover data now in real time”Tania Birch, senior program manager at Google Earth Outreach, explains that the tool meets a very specific need: The earth’s crust evolved day after day. “Our planet is changing dramatically in a way that is visible even from space.”, He notes. Whether we are talking about change due to environmental issues or human activity, There is enough to transform the landscape every day : Fire, flood, deforestation, development of urban areas etc.

“Detailed information about these changes and their effects on people, climate and ecosystems can help governments and researchers develop useful solutions and reduce their impact on issues such as climate change, food insecurity and biodiversity loss.”The engineer added.

From August to September 2021, the California wildfires are represented by Dynamic World.

And here comes Dynamic World: the processing of data collected by the artificial intelligence of this platform makes it possible to update the land cover map “in near real time” and on a global scale.

Data is an astronomical quantity

Where most cartographic solutions are satisfied to allocate a single type of ground occasion for a given area – such as a forest, a city, a field or even snow – Dynamic World is able to display several of them. The teams working on the tool have been identified Nine “important” land cover types : Water, flooded vegetation, constructed area, trees, crops, bare soil, grass, shrubs and snow / ice.

“Using Dynamic World AI and Cloud Computing to detect a combination of different types of land covers and draw conclusions about the possibility of each of the nine types appearing in each pixel of satellite imagery.”Tania Birch explains. The results are therefore surgically precise.

To achieve such a level of rendering and, above all, to ensure daily updates, About 5,000 satellite photos provided daily by Copernicus Sentinel-2, analyzing in detail the artificial intelligence of Dynamic World. An AI may not seem like digesting 5,000 photos per day, but when you know itOne pixel of each shot corresponds to more than 100 m² of land on the ground, It still presents a lot of information to process. Currently, Google has a history of tools that go back to June 2015 “Two days ago”.

A powerful tool for decision makers

“With this information, people – such as scientists and policy makers – can observe and understand land and ecosystems so that they can make more accurate predictions and effective plans for protecting our planet in the future.”Tania Birch says. We hope that such tools can effectively help predict some environmental issues.. What is certain for the moment is that Dynamic World Hall is a privileged witness to change, sometimes tragic, that takes place on the surface of the earth.

If you want to explore Dynamic World yourself, this is possible: A site provides access to ultra-accurate soil mapping in real time around the world. Good visit!
