Intercomparison of the DART model and GEDI simulator for simulating GEDI waveforms in forests
International Journal of Applied Earth Observations and GeoinformationThe launch of GEDI opens a new era of forest structure monitoring using full-waveform LiDAR from space. Simulation of GEDI waveform is of great importance for the algorithm design and forest structure metric estimation.

Multi-resolution gridded maps of vegetation structure from GEDI. [PDF]
Sci DataLarge-extent maps of three-dimensional vegetation structure are important for understanding the hydrologic cycle, climate, carbon fluxes, and habitat. We aggregated over 7 billion lidar shots from the Global Ecosystem Dynamics Investigation (GEDI) to produce analysis-ready, gridded rasters of 36 vegetation structure metrics at three spatial resolutions

Spaceborne LiDAR for characterizing forest structure across scales in the European Alps
Remote Sensing in Ecology and Conservation, 2023 The launch of NASA's Global Ecosystem Dynamics Investigation (GEDI) mission in 2018 opens new opportunities to quantitatively describe forest ecosystems across large scales. While GEDI's height‐related metrics have already been extensively evaluated, the

GeDi: Generative Discriminator Guided Sequence Generation [PDF]
Findings of the Association for Computational Linguistics: EMNLP 2021, 2021 While large-scale language models (LMs) are able to imitate the distribution of natural language well enough to generate realistic text, it is difficult to control which regions of the distribution they generate. This is especially problematic because datasets used for training large LMs usually contain significant toxicity, hate, bias, and negativity.
