xls:Position

The Position ADT. Normally used to represent an observation/calculated position for a mobile terminal, but can be any position used by the platform. Contains Point with optional Shape, QoP, Speed, Direction and Time. Also has levelOfConfidence attribute.

Element information

Content

• Sequence [1..1]
  1. gml:Point [1..1]    
  2. Choice [0..1]
     • xls:Ellipse    
     • gml:CircleByCenterPoint    
     • xls:CircularArc    A CircularArc is a geometric object defined by LIF (MLP 3.0) which is defined by two arcs (r[1] > r[2]), and two lines that radiate from the center point, at a given start angle and end angle. As with the definitions for circle and ellipse, this object is defined by its parameters: a center point, two radii, and two angles. This represenation can be used only in 2D.
     • gml:Polygon    
     • xls:MultiPolygon    
  3. xls:QoP [0..1]    QoP as defined by LIF.
  4. xls:Time [0..1]    
  5. xls:Speed [0..1]    
  6. xls:Direction [0..1]
