Overview

Geometries define a 3D airspace horizontally. It's either exactly one circle or at least three points, arcs and borders (the last of which has to be a point with the same coordinates as the first).

For a geometry to be valid, it must be comprised of either:

  • exactly one point

  • exactly one circle

  • at least three points, arcs or borders (the last of which a point with identical coordinates as the first)

Cheat Sheet in Pseudo Code:

geometry = AIXM.geometry
geometry << AIXM.point or AIXM.arc or AIXM.border or AIXM.circle

Examples:

Built by passing elements to the initializer

geometry = AIXM.geometry(
  AIXM.point(...),
  AIXM.point(...)
)

Built by adding elements

geometry = AIXM.geometry
geometry << AIXM.point(...)
geometry.concat [AIXM.point(...), AIXM.point(...), ...]
