cross-sensor-cal

Overview

DO NOT EDIT OUTSIDE MARKERS The Cross‑Sensor Calibration workflow is organized into five sequential stages. Each stage consumes artifacts from the previous one and produces standardized outputs for the next.

Raster

• Inputs: raw NEON AOP HDF5 flightlines and sensor configuration files
• Outputs: corrected, resampled rasters in ENVI/GeoTIFF format

Sorting

• Inputs: processed rasters and ancillary metadata
• Outputs: directory tree grouped by site/date with manifests for downstream use

Pixel Table

• Inputs: sorted rasters and optional vector masks or polygons
• Outputs: tabular spectra with pixel coordinates and metadata (*_pixels.csv)

Spectral Library

• Inputs: pixel tables from one or more scenes
• Outputs: aggregated spectral library files (spectra_library.*) ready for analysis

MESMA

• Inputs: spectral library and target rasters
• Outputs: Multiple Endmember Spectral Mixture Analysis results and fractional cover maps

Who is this for?

Researchers and practitioners working with NEON AOP flightlines, drone imagery, or Landsat scenes who need a reproducible pipeline for cross‑sensor spectral analysis.
