LiDAR Terrain Cube Renderer

A module that turns raw LiDAR point clouds and gridded data cubes into aligned rasters and a simple 3D scene for inspection.

Capabilities

Create DEM from LiDAR

• Generates a GeoTIFF elevation raster from a LAS/LAZ file clipped to [xmin, ymin, xmax, ymax] bounds at the requested resolution, returning the output path. @test
• Raises a descriptive error when the requested bounds fall completely outside the LiDAR footprint. @test

Export data cube slice

• Extracts a single variable and time index from a NetCDF/HDF data cube into a GeoTIFF aligned to the DEM's extent/CRS and resolution, returning the output path. @test

Render 3D overlay

• Builds a lightweight 3D HTML rendering that displays the DEM surface and an optional overlay raster, writing to a provided HTML path and returning it. @test
