Fill missing Munsell colors on a PedonRecord from Vis-NIR spectra

Source: R/spectra-munsell.R
fill_munsell_from_spectra.Rd

High-level helper that runs predict_munsell_from_spectra per horizon over the Vis-NIR spectra in pedon$spectra$vnir and writes the resulting hue / value / chroma back to the matching horizon rows via pedon$add_measurement(..., source = "predicted_spectra").

Usage

fill_munsell_from_spectra(pedon, overwrite = FALSE, verbose = TRUE)

Arguments

pedon

A PedonRecord that has $spectra$vnir populated (rows = horizons, cols = wavelengths).

overwrite

If TRUE, overwrite existing Munsell measurements. Default FALSE (only fills horizons whose Munsell is currently NA).

verbose

If TRUE (default), prints a per-horizon summary.

Value

The pedon, invisibly. Provenance entries with source = "predicted_spectra" are appended.

Details

This is the operational answer to the v0.9.35 Argissolo color confusion: when surveyor Munsell colors are missing and the user has Vis-NIR (e.g. from OSSL), call this helper, then re-run classify_sibcs – the v0.9.45 "color-undetermined" fallback will lift, and the classification will descend to subordem / grande grupo / subgrupo with proper evidence_grade.
