![]() ![]() This makes sense: About 70 percent of Earth’s land surface is covered by clouds every day. Taken individually, most of these pictures captured by the Landsat sensors include some clouds. (Landsat 7 and Landsat 8 are only the most recent of these craft.) government’s Landsat program, a series of satellites that have photographed the Earth’s surface every 16 days since the 1970s. Mosaicking draws upon the vast archives of imagery that have been created by the U.S. Instead, Google engineers used a recently developed cartography technique called mosaicking. ![]() Neither of the images above were captured on a single shoot by a solitary satellite, the way that a camera might capture a snapshot. ![]() This “ghostly” runway effect points to how Google makes its maps cloudless in the first place. Its remoteness gives it a unique ecology, but-given its location in the middle of the tropical Indian Ocean-it is frequently obscured by clouds. Almost a thousand miles from Australia, the island was largely untouched by human settlement until the past two centuries. The improvements can be seen in the new map’s depiction of Christmas Island. Google had not updated its low- and medium-resolution satellite map in three years. Most importantly, this new map contains fewer clouds than before-only the second time Google has unveiled a “cloudless” map. The new map, which activates this week for all users of Google Maps and Google Earth, consists of orbital imagery that is newer, more detailed, and of higher contrast than the previous version. Google has added nearly 1.5 trillion pixels of new data to its service *. ![]() On Monday, it gets a makeover, and its many users will see something different when they examine the planet’s forests, fields, seas, and cities. Timelapse in Google Earth is possible because of the commitment to open and accessible data through NASA and the United States Geological Survey’s Landsat program (the world’s first and longest-running civilian Earth observation program) and the European Union’s Copernicus program with its Sentinel satellites.Ĭheck out the updated visualization today in Google Earth at g.co/timelapse, and on YouTube via g.co/timelapsevideos.More than 1 billion people use Google Maps every month, making it possibly the most popular atlas ever created. And people are using this imagery to convey the effects of these changes, like the 2022 documentary The Territory which uses Timelapse to show the devastation of deforestation across the Amazon and its effect on local communities. From researchers to teachers, anyone can use these videos to better understand our changing planet. You can also view a library of over 800 Timelapse videos for more than 300 locations at g.co/TimelapseVideos. The imagery also captures ways cities have adapted to combat climate change - like offshore wind farms in Middelgrunden, Denmark and a large-scale solar installation in Granada, Spain. Timelapse in Google Earth is a global, zoomable time-lapse video of the planet, providing evidence of earth’s dynamic changes - from irrigation systems emerging in the deserts of Egypt and meandering rivers shifting over time in the Amazon rainforest in Pucallpa, Peru to volcanic eruptions, logging and wildfires changing the landscape of California’s Lassen National Forest. ![]()
