Validate a bathymetric or elevation raster — validate_bathy • blueterra

Checks that an object is a readable terra::SpatRaster with dimensions, layers, and values suitable for terrain analysis.

Usage

validate_bathy(
  x,
  require_crs = FALSE,
  require_values = TRUE,
  allow_multi = FALSE
)

Arguments

x: A raster-like object accepted by as_bathy().
require_crs: Logical. If TRUE, require a declared CRS.
require_values: Logical. If TRUE, require raster values.
allow_multi: Logical. If FALSE, warn when more than one layer is supplied.

Value

Invisibly returns the input raster.

Details

Validation does not decide whether values represent positive depth or negative elevation. Use check_bathy_units(), set_depth_positive(), or set_depth_negative() when sign convention matters.
