Check that the supplied grids cover the domain — check_grid

Compares each raster's extent against the reference fabric's extent. A primary grid that does not cover the domain is an error: the most common cause is a per-domain configuration inheriting a grid meant for somewhere else, which otherwise builds without complaint. A fallback that does not reach the domain is reported and left alone, since it simply never fires.

Usage

check_grid_coverage(
  reference_gpkg,
  fdr_path,
  fac_path,
  fallback_fdr_path = NULL,
  fallback_fac_path = NULL,
  vpuid = NA_character_,
  min_coverage = 0.99,
  strict = TRUE
)

Arguments

reference_gpkg: Path to the reference fabric.
fdr_path, fac_path: Primary grid paths.
fallback_fdr_path, fallback_fac_path: Optional fallback grid paths.
vpuid: Optional VPU being built. When supplied and the reference carries a vpuid column, coverage is measured against that VPU's extent rather than the whole reference, so a per-VPU grid tile is judged on the ground it is meant to cover.
min_coverage: Minimum share of the reference extent a primary grid must cover. Default 0.99.
strict: If TRUE (default) an uncovered primary grid raises an error.

Value

Invisibly, a named numeric of coverage fractions.
