Load KSSL pedons enriched with NASIS morphology — load_kssl_pedons_with

Joins the NCSS Lab Data Mart GeoPackage with the NASIS Morphological SQLite to produce PedonRecord objects whose horizons table has BOTH lab chemistry + physics AND field morphology (Munsell, structure, clay films, slickensides, cracks). Required for the morphological-evidence diagnostics (argic clay-films, vertic_horizon slickensides, mollic_epipedon_usda Munsell, etc.) to fire on KSSL profiles – the lab gpkg alone has none of those.

Usage

load_kssl_pedons_with_nasis(
  gpkg,
  sqlite,
  head = NULL,
  require_b_horizon = TRUE,
  verbose = TRUE
)

Arguments

gpkg: Path to ncss_labdata.gpkg.
sqlite: Path to NASIS_Morphological_*.sqlite.
head: Optional integer; load only the first N classified pedons. Useful for parser validation / scaling.
require_b_horizon: If TRUE (default), drops pedons whose deepest horizon's bottom_cm < 30.
verbose: If TRUE (default), emits progress messages.

Value

A list of PedonRecord objects.
