4.10.3. Point Properties
[4.10. Cross-section Data]

Point properties represent important locations along the cross-section geometry. They may include such things as the thalweg, or left or right banks. Point properties are stored in a continuous list and reference the cross-section (by ID) to which they are associated.

Points are defined by their IDs and x,y,z coordinate pairs. Points will also contain attributes according to the type of point being represented (i.e. node, vertex, hydraulic structure, etc.). A point will be referenced for each cross-section whose spatial origin definition is give as Point.
