  • Anthropogenic Human Influenced Ecosystems - NASA Earthdata
    Our datasets useful to the study of human-influenced ecosystems include crop extent maps, urban air quality measurements, and land cover surveys These measurements and higher-order data products enable important studies into how humans shape Earth and how we can better care for ourselves and our home Get Human-Influenced Ecosystems Data
  • Terrestrial Ecosystems | NASA Earthdata
    NASA's terrestrial ecosystem data give researchers the ability explore the creature and plant communities living on land virtually anywhere on Earth
  • Global Ecosystem Dynamics Investigation Lidar | NASA Earthdata
    The Global Ecosystem Dynamics Investigation (GEDI) instrument is a full-waveform lidar installed on the International Space Station that produces detailed observations of the 3D structure of Earth’s surface GEDI's three lasers precisely measure forest canopy height, canopy vertical structure, and surface elevation By accurately measuring forests in 3D, GEDI data play an important role in
