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.

GEDI is a full-waveform lidar instrument that makes detailed measurements of the 3D structure of the Earth’s surface. Lidar is an active remote sensing technology (the laser version of radar) which uses pulses of laser light to measure 3D structure.

GEDI laser ranging observations provide the missing piece - high resolution measurements of the Earth’s 3D structure. … enabling us to address urgent questions about the Earth. Global changes are fundamentally altering Earth’s tropical and temperate forests …

2024年6月7日 · GEDI 仪器是一种大地测量级光探测和测距（lidar）激光系统，由 3 个激光器组成，可产生 8 个平行的观测轨迹。 每个激光器每秒发射 242 次，并在测量 25D 结构的表面上照亮 3 m 的光斑（足迹）。

The GEDI instrument is a geodetic-class, light detection and ranging (lidar) laser system comprised of 3 lasers that produce 8 parallel tracks of observations. Each laser fires 242 times per second and illuminates a 25 m spot (a footprint) …

From its vantage point on the International Space Station (ISS), GEDI uses lidar to provide the first global, high-resolution observations of forest vertical structure. GEDI addresses three core science questions: What is the aboveground carbon balance of the land surface?

2025年1月7日 · GEDI is a full-waveform light detection and ranging (lidar) instrument that produces high-resolution laser ranging observations of the 3D structure of the Earth’s surface. GEDI collects data globally between 51.6° N and 51.6° S latitudes at the highest resolution and densest sampling of any lidar instrument in orbit to date.

2023年8月25日 · GEDI（Global Ecosystem Dynamics Investigation）是一项由NASA资助的计划，旨在收集全球范围内的激光雷达高度数据，以研究地球上森林等生态系统的结构和功能。文件路径应替换为实际文件路径。使用pyGEDI，我们可以将GEDI数据导入到Python中，以便于数据处理

GEDI's LIDAR system provides precise geolocated elevation data that drastically improve global Digital Elevation Models (DEMs). Owing to the vast number of data points that GEDI is capable of collecting it will provide a stronger baseline for DEMs and remove more system errors compared to …

Launched December 5, 2018, the scientific goal of the Global Ecosystem Dynamics Investigation Lidar (GEDI) is to characterize the effects of changing climate and land use on ecosystem structure and dynamics to enable radically improved quantification and understanding of the Earth's carbon cycle and biodiversity.
