Collect static (non-time-varying) PRIO-GRID data

Source: R/build_priogrid.R
read_pg_static.Rd

Loads all static variables and returns them either as a data.table or as a list of rasters. See pgvariables for available variables. If an official release is specified (or version, type and hashes are NULL), then this is downloaded if this is not already done.

Usage

read_pg_static(
  version = NULL,
  type = NULL,
  spatial_hash = NULL,
  temporal_hash = NULL,
  as_raster = FALSE,
  test = FALSE,
  overwrite = FALSE
)

Arguments

version

Character string specifying PRIOGRID version.

type

Character string specifying release type (e.g., "05deg_yearly").

spatial_hash

Character string with 6-character spatial hash (custom only).

temporal_hash

Character string with 6-character temporal hash (custom only).

as_raster

Logical. If TRUE, returns list of SpatRasters. If FALSE (default), returns data.table.

test

Logical. If TRUE, prints coverage summary for each variable.

overwrite

Logical. If FALSE (default) and cached file exists, returns cached data. If TRUE, rebuilds from individual variables.

Value

data.table with pgid as rows and variables as columns, or list of terra SpatRasters if as_raster=TRUE

Examples

if (FALSE) { # \dontrun{
  # Load as data.table
  pg_dt <- read_pg_static()

  # Test coverage
  pg_dt <- read_pg_static(test = TRUE)

  # Load as rasters
  pg_rast <- read_pg_static(as_raster = TRUE)

  # Load official release
  pg_dt <- read_pg_static(version = "3.0.1",
                          type = "05deg_yearly")
} # }
