Retrieve municipal boundaries — retrieve

Retrieves Ontario municipal boundaries from the LIO Open Data REST service, either the upper/district tier (LIO_Open03/13) or the lower/single tier (LIO_Open03/14).

Usage

retrieve_municipal(
  tier = c("upper", "lower"),
  simplify = TRUE,
  refresh = FALSE,
  max_age = NULL
)

Arguments

tier: Character. Either "upper" (upper-tier and district municipalities) or "lower" (lower-tier and single-tier municipalities). Defaults to "upper".
simplify: Logical. If TRUE (the default), requests generalized geometry from the service.
refresh: Logical. If TRUE, bypasses any cached copy and re-fetches from the live API. Defaults to FALSE.
max_age: Numeric or NULL. Maximum acceptable cache age in days; older entries are re-fetched. Defaults to NULL.

Value

An sf object of municipal boundary polygons, with source_url, source_name, and retrieved_at attributes attached.

Examples

if (FALSE) { # \dontrun{
# Retrieves from the Ontario LIO REST service and caches the result.
upper_tier <- retrieve_municipal("upper")
} # }
