| Popis: | International audience; Changes to the Earth's biosphere have reached a critical point. It's abundantly clear that we can no longer halt those changes that have resulted from humaninduced modifications to the Earth's systems (1, 2). The climate crisis will fundamentally disrupt weather patterns, raise sea levels, alter biogeographic distributions, and much more. Research across disciplines from archaeology to zoology shows that terrestrial environments comprise irreplaceable archives of past human and evolutionary activity. Our rapidly changing Earth presents a grand challenge for humanity: We must preserve or record our cultural and ecological heritage, along with information about habitats critical for biodiversity, before they are lost completely. But this challenge brings up a profoundly important question: How best do we accomplish this recording, as quickly and with as much detail as possible? Some of this documentation is already underway. For example, there are archives of multi-spectral remote sensing products that are freely open to all, most notably the U.S. Geological Survey (USGS) archives (earthexplorer.usgs.gov) that include Landsat multi-spectral images dating back to the 1970s for much of the Earth's surface, as well as aerial photographs that date to earlier. What's missing from these archives is three-dimensional data that record the structure of the Earth's forest cover as well as the cultural and ecological features found beneath forest canopies. There have been calls to use remote sensing technologies, such as light detection and ranging (Lidar), to fill in this gap and record these broad areas of the |
