Class: AIXM::Feature::ObstacleGroup

Inherits:
AIXM::Feature show all
Includes:
Concerns::Association, Concerns::Remarks
Defined in:
lib/aixm/feature/obstacle_group.rb

Overview

Groups of obstacles which consist of either linked (e.g. power line towers) or unlinked (e.g. wind turbines) members.

Cheat Sheet in Pseudo Code:

obstacle_group = AIXM.obstacle_group(
  source: String or nil        # see remarks below
  region: String or nil
  name: String or nil
)
obstacle_group.xy_accuracy = AIXM.d or nil
obstacle_group.z_accuracy = AIXM.d or nil
obstacle_group.remarks = String or nil
obstacle_group.comment = Object or nil
obstacle_group.add_obstacle(   # add an obstacle to the group
  AIXM.obstacle
)
obstacle_group.add_obstacle(   # add an obstacle to the group and link
  AIXM.obstacle,               # it to the obstacle last added to the group
  linked_to: :previous,
  link_type: LINK_TYPES
)
obstacle_group.add_obstacle(   # add an obstacle to the group and link
  AIXM.obstacle,               # it to any obstacle already in the group
  linked_to: AIXM.obstacle,
  link_type: LINK_TYPES
)

Please note: As soon as an obstacle is added to an obstacle group, the xy_accuracy and z_accuracy of the obstacle group overwrite whatever is set on the individual obstacles. On the other hand, if the obstacle group has no source set, it will inherit this value from the first obstacle in the group.
