Create template and region of interest (ROI) rasters in an output directory based on input vector ROI, resolution and projection.

Usage

createDomain(
  domain,
  res = 100,
  proj = NULL,
  outdir,
  quiet = TRUE,
  overwrite = TRUE
)

Arguments

domain: SpatVect or SimpleFeatures object contianing the domain of the analysis. If this contains multiple features, they will be aggregated.
res: Resolution, in project units, of the output template and mask rasters. Defaults to 100.
proj: Projection (CRS) object for the template and mask rasters to be produced, as epsg string eg. "epsg:3308". If none is provided, will use projection of input domain.
outdir: Output directory to write the rasters
quiet: Write progress diagnostics (TRUE/FALSE)
overwrite: Overwrite files (TRUE/FALSE)

Value

template
