Cross-Sensor Calibration

Cross-Sensor Calibration provides a Python pipeline for processing NEON Airborne Observation Platform hyperspectral flight lines and resampling them to emulate alternate sensors in a reproducible, scriptable workflow.

5-minute Quickstart

# 1. set up workspace
mkdir -p data/SITE

# 2. download a tiny flight line (placeholders shown)
python -m bin.download --site SITE --flight FLIGHT_LINE

# 3. run the full pipeline
python -m bin.pipeline data/SITE/FLIGHT_LINE

# 4. peek at resampled outputs
ls data/SITE/FLIGHT_LINE/resampled

Replace SITE with a NEON site code and FLIGHT_LINE with an actual line identifier.
