Satellite view of space12/20/2023 Google Maps and Google Earth are the most well-known examples many of us turn to when we want to view satellite images online. Instead, these images are stitched together in a process called photogrammetry to create a seamless user experience. Simply put, a satellite view of a map, for example, does not consist of a single image. So it's necessary to take hundreds of thousands of smaller photos, which can vary by date, time of day, and source material. But, Earth is too large to capture all the details required for a single high-resolution image. A large sediment plume can be seen traveling westward into the Pacific in the left of the image.SCROLL TO CONTINUE WITH CONTENT How are satellite images created?Ī satellite image is taken from hundreds of miles above our heads and can help track weather conditions or view the world around us. Here, the murky waters mix before flowing into the larger bay area, which is connected to the Pacific Ocean via the Golden Gate Strait. In the upper right of the image, the delta of the Sacramento and San Joaquin rivers is visible – with the brown, sediment-filled water flowing down into San Pablo Bay. The densely populated urban areas around the bay contrast strongly with the surrounding green forest and park areas. San Francisco Bay, almost 100 km (62 mi) in length, is a shallow estuary surrounded by the San Francisco Bay Area – an extensive metropolitan region that is dominated by large cities such as San Francisco, Oakland, and San Jose. The Copernicus Sentinel-2 mission takes us over San Francisco Bay in the US state of California.
