Retrieve ACE ANSP airspace geometries for a given AIRAC cycle

Source: R/airspaces.R
ansp_sf.Rd

Returns ANSP (Air Navigation Service Provider) airspace geometries from the ACE (ATM Cost-Effectiveness) benchmarking dataset as an sf object for the specified CFMU AIRAC cycle.

Airspaces with code AIRPORT, UNKNOWN or MILITARY are excluded.

Usage

ansp_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:

  • airac_cfmu: the AIRAC cycle id

  • id: the airspace identifier

  • code: the ANSP code

  • name: the ANSP name

  • ace_code: the ACE benchmarking code

  • min_fl: the minimum flight level

  • max_fl: the maximum flight level

  • airspace_type: the airspace type

  • geometry: the airspace polygon geometry

Note

You need to either provide a connection conn that has access to ENV_SP.AIRSPACE, PRU_CFMU_ANSP 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{
ansps <- ansp_sf(cfmu_airac = "481")

# write to GeoJSON
sf::st_write(ansps, "ansp_ace_481.geojson", driver = "GeoJSON")

# if you re-use DB connections
conn <- eurocontrol::db_connection("PRU_DEV")
ansps <- ansp_sf(conn = conn, cfmu_airac = "481")

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