Parse PRISME Airspace format

parse_airspace_prisme reads the airspace PRISME format and returns a tibble where each row describes an airspace.

Each airspace in PRISME format is described by:

1. Airspace description (one row):

   • an airspace Unit code

   • a Elementary Sector code

   • minimum flight level

   • maximum flight level

   • the number of vertices of the polygon of the Elementary Sector

   • the coordinates of vertices

2. vertex coordinates (as many rows as the number of vertices)

Usage

parse_airspace_prisme(lines)

Arguments

lines

text lines of the PRISME airspace representation

Value

a tibble of airspaces (CRS = 4326)
