[carlos-alberto-silva] rGEDI 0.6.0

c.silva@ufl.edu (Carlos Alberto Silva) — Wed, 21 Oct 2026 15:01:27 GMT

Provides an end-to-end workflow for NASA Global Ecosystem Dynamics Investigation (GEDI) Level 1B, Level 2A, Level 2B, Level 3, Level 4A, and Level 4B data. Functions search NASA catalogues, download granules, stream HDF5 products from Earthdata Cloud, and extract geolocations, waveforms, elevation and relative-height metrics, canopy cover, plant area profiles, and aboveground biomass. Methods quality-filter and spatially clip HDF5, tabular, and raster products; calculate footprint and polygon statistics; create gridded summaries; and visualize orbital tracks and measurements. The package also simulates GEDI-like waveforms from airborne laser-scanning point clouds and supports spatial sampling, predictive modelling, ancillary-data extraction, and wall-to-wall upscaling with optional Google Earth Engine workflows.

[carlos-alberto-silva] ICESat2VegR 0.0.6

c.silva@ufl.edu (Carlos Alberto Silva) — Thu, 15 Oct 2026 10:28:56 GMT

Provides tools for downloading, reading, processing, visualizing, and exporting NASA's ICESat-2 ATL03 (Global Geolocated Photon Data) and ATL08 (Land and Vegetation Height) products. Supports photon- and segment-level analysis, spatial sampling, gridding, statistical and machine-learning modeling, and integration with 'Google Earth Engine' () for wall-to-wall mapping of vegetation structure and other land attributes.

[carlos-alberto-silva] rFDS 0.0.1

c.silva@ufl.edu (Carlos Alberto Silva) — Tue, 14 Oct 2025 15:32:58 GMT

rFDS provides an interface between LiDAR-based vegetation structure data and the Fire Dynamics Simulator (FDS) for modeling forest and vegetation fire behavior. The package enables the conversion of classified LiDAR point clouds into voxelized fuel structures, generation of FDS input files, and automated simulation workflows for fire dynamics and fuel consumption analysis.
