Footprints of Planet Open Data

Mineral and mine-waste alteration mapping from Planet Tanager 426-band VSWIR at Bingham Canyon and Goldfield — library-anchored screening with EMIT cross-check

This repository contains the Earth Data Analysis Center (EDAC) team's submission for Planet's Tanager Open Data Competition.

Shared data layer for Planet Tanager VSWIR analysis: STAC ingest, QA masking, band utilities, SRF simulation, reproducible sampling

Various demonstration code in my programming languages.

Methane plume detection pipeline using Planet Tanager hyperspectral data, producing GIS-ready raster and vector outputs for environmental monitoring.

Open-source Python tools for tracing atmospheric-correction uncertainty into Tanager and EMIT reflectance algorithms.

Convert Planet Tanager HDF5 radiance to surface reflectance via ISOFIT atmospheric correction; validates against NASA EMIT

Fiji/ImageJ plugin toolkit for Planet Tanager hyperspectral scenes — import, 57 spectral indices, spectra, georeferenced export. With a matching NumPy reference engine.

Subpixel fire temperature from Tanager hyperspectral imagery — without a thermal band. Planck fitting across 154 SWIR bands, validated against VIIRS 2.5 min apart.

Matched-filter methane detection for Planet Tanager-1 hyperspectral imagery, with a validation chain that separates CH₄ absorption from surface mineralogy. Work in progress; detection method not yet validated.
