Retrieve ACC/OAC airspace geometries for a given AIRAC cycle

Source: R/airspaces.R
acc_sf.Rd

Returns ACC (Area Control Centre) and OAC (Oceanic Area Control Centre) airspace geometries as an sf object for the specified CFMU AIRAC cycle.

Usage

acc_sf(conn = NULL, cfmu_airac)

Arguments

conn

Database connection or instantiate the default one.

cfmu_airac

the AIRAC cycle number (CFMU format), e.g. "517" or 517. Both character and numeric inputs are accepted. See airac::cfmu_airac() to look up the cycle number for a given date.

Value

An sf object with the following columns:

  • AC_ID: the AIRAC cycle id

  • AV_AIRSPACE_ID: the airspace identifier

  • MIN_FLIGHT_LEVEL: the minimum flight level

  • MAX_FLIGHT_LEVEL: the maximum flight level

  • NAME: the airspace name

  • CODE: the airspace code

  • AIRSPACE_TYPE: the airspace type (ACC or OAC)

  • geometry: the airspace polygon geometry

Note

You need to either provide a connection conn that has access to ENV_SP.AIRSPACE, PRU_STAT_AUA and SWH_MAP or go with the default which uses PRU_DEV to establish a db_connection().

The sf package is required but only suggested; install it if not available.

Examples

if (FALSE) { # \dontrun{
acc <- acc_sf(cfmu_airac = "517")

# write to GeoJSON
sf::st_write(acc, "acc-517.geojson", driver = "GeoJSON")

# if you re-use DB connections
conn <- eurocontrol::db_connection("PRU_DEV")
acc <- acc_sf(conn = conn, cfmu_airac = "517")

# ... do something else with conn
# ...
# then manually close the connection to the DB
DBI::dbDisconnect(conn)
} # }
