Retrieve Public Health Unit boundaries — retrieve

Retrieves Ontario Public Health Unit (PHU) boundaries from the LIO Open Data REST service (LIO_Open09/44).

Usage

retrieve_phu(simplify = TRUE, refresh = FALSE, max_age = NULL)

simplify: Logical. If TRUE (the default), requests generalized geometry from the service (maxAllowableOffset = 1e-04, i.e. 0.0001 degrees, since the service returns EPSG:4326 – roughly 11 m on the ground) to reduce payload size. Set to FALSE if you need full-precision geometry, but be aware that the LIO service may fail to serve the full-resolution layer intermittently; if that occurs, retry with simplify = TRUE or set refresh = TRUE.
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.

An sf object of PHU boundary polygons, with source_url, source_name, and retrieved_at attributes attached for provenance.

if (FALSE) { # \dontrun{
# Retrieves from the Ontario LIO REST service and caches the result.
phu <- retrieve_phu()
} # }
