Convert vector data to PRIO-GRID

Usage

pg_from_vector(
  x,
  variable,
  value = NULL,
  aggregation,
  geometry = c("auto", "point", "line", "polygon"),
  time = NULL,
  time_column = NULL,
  group_columns = NULL,
  keep_empty = FALSE,
  return = c("data", "raster", "result"),
  config = priogrid::pg_current_config(),
  filename = NULL,
  overwrite = FALSE
)

Arguments

x: An sf object, SpatVector, or vector-file path.
variable: Name of the resulting variable.
value: Optional source value column.
aggregation: Geometry-specific aggregation rule.
geometry: Geometry type, or "auto".
time: Optional static observation date or year.
time_column: Optional observation-date column.
group_columns: Optional additional grouping columns.
keep_empty: For points, complete unobserved cells with zero when the aggregation has a meaningful zero.
return: One of "data", "raster", or "result".
config: A PRIO-GRID configuration object.
filename: Optional output filename.
overwrite: Replace an existing output file?

Value

A data frame, SpatRaster, or pg_result.

Examples

events <- sf::st_as_sf(
  data.frame(longitude = c(10, 20), latitude = c(50, 60)),
  coords = c("longitude", "latitude"), crs = 4326
)
config <- priogrid::pg_config(nrow = 18, ncol = 36, verbose = FALSE)
pg_from_vector(
  events,
  variable = "event_count",
  aggregation = "count",
  config = config
)
#>   pgid event_count
#> 1  488           1
#> 2  525           1
