land:ReducedArcObservation

As we discussed this element is used to provide measured information for calculating boundary arcs. The definition information required is quite different to the curve element

Element information

Content

• Sequence [1..1]
  1. land:TargetPoint [0..1]    Represents a 2D or 3D location for the targetIt is defined by either a coordinate text value ("north east" or "north east elev") or a CgPoint number reference "pntRef" attribute.
  2. land:OffsetVals [0..1]    offsetInOut: -ve = offset in towards inst, +ve = offset away from inst offsetLeftRight: -ve = left, +ve = right (as viewed from instrument) offsetUpDown: -ve = down, +ve = up
  3. Choice [0..*]
     • land:FieldNote [0..*]    Place the note as a text value between the FieldNote element tags. You may also place any valid XML structure inside this tag.
     • land:Feature [0..*]    Used to include additional information that is not explicitly defined by the LandXML schema, Feature may contain one or more Property, DocFileRef or nested Feature elements. NOTE: to allow any valid content, the explicit definitions for Property, DocFileRef and Feature have been commented out, but are still expected in common use.Each Property element defines one piece of data.
