It may have 1 or more Outlet elements.

Element information

Content

• Sequence [1..1]
  1. Choice [1..1]
     • land:PntList2D    A sequential space delimited list of 2D coordinates with a minimum of 2 points (4 values). It is primarily used for ProfileSurf to hold the list of station/elevations and CrossSectSurf for offset/elevation. Example: "0.000 86.52 6.267 86.89 12.413 87.01 26.020 87.83"
     • land:PntList3D    A sequential space delimited list of 3D coordinates with a minimum of 2 points (6 values). Primarily used to store lists of northing/easting/elevation for Terrain Surface data. Example: "0.000 86.52 50.0 6.267 86.89 50.0 12.413 87.01 50.0 26.020 87.83 50.0"
  2. land:Outlet [0..*]    Identifies a drain point from the watershed with a space delimited "northing easting elevation" value.If it drains to another known watershed, then the name of that watershed is identified by the "refWs" attribute.
  3. 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.
