land:CoordGeom

A sequential list of Line and/or Curve and/or Spiral elements.

After the sequential list of elements an optional vertical geometry 
			may be defined as a profile, which may be as simple as a list of PVIs (point to point 3D line string).

Element information

Content

• Sequence [1..1]
  1. Choice [1..*]
     • land:Line [0..*]    Modified to include official ID, as with all CoordGeom elements
     • land:IrregularLine [0..*]    Used to record lines that are irregular such as river boudaries etc. It has Start and End point elements and a list of intermediate points. Point list should also include the start and end points.
     • land:Curve [0..*]    The distance from the Start to the Center provides the radius value.The rotation attribute "rot" defines whether the arc travels clockwise or counter-clockwise from the Start to End point.
     • land:Spiral [0..*]    An "infinite" spiral radius is denoted by the value "INF". This conforms to XML Schema which defines infinity as "INF" or "-INF" for all numeric datatypes
     • land:Chain [0..*]    A text value that is a space delimited list of CgPoint names that form a linear connected chain. example: 1 23 45 34 represents a linear connection between CgPoint name 1, 23, 45 and 34.
  2. 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.
