Suggested model for "Norsk Luftfart" reporting (Site, Location, PositionPoint)

[ThomasRanvikEriksen]

Reference: Syntax for Compound: #284

We need in the first version to address the classes for: "Linje Trasee" and "Pole"

We also need to address the attributes:

status (Tower/Line) komponentident (Tower/Line) verifisertRapporteringsnøyaktighet (Tower/Line) komponentkodeverdi (Tower/Line) vertikalAvstand (Tower/Line) luftfartshindermerking (Tower/Line) luftfartshinderlyssetting (Tower/Line) luftspennType (Line) anleggsbredde (Line) høydereferanse (Tower/Line) mastType (Tower)

"Linje Trasee":

"høydereferanse":

• Definition:
• Choices:
• Solution: Use zPosition as the lines coordinates. If you want the bottom you need to subtract the Poles height Not sure about the definition here.

"Pole"

"høydereferanse":

• Definition:
• Choices: Fot (Bottom), Topp (Top)
• Solution: Use zPosition as the bottom point of the pole and structure height as the height. If you want to know the zPosition for the top of Pole it is zPosition + height

Here is an shorten geojson example that Kartverket accepts:

Structure components as used in DIGIN Produktdata. Asset groups in bold

Line support (”mast”) – complete structure excluding wires: Line supports are the general functional structures (container) to keep proper spacing between the conductors and between conductors and ground. Line supports consist of several parts like poles (single or multiple), a tower (single only and not in combination with poles), cross arms, foundations, insulators etc. Line supports can be divided into numerous different components depending on what the data model must cover. In the following sub sections some parts (groups) that are relevant for asset management is covered and not necessary every single piece of equipment.

Pole (Norwegian term “stolpe”): Poles are part of a line support and is a single pole of wood, concrete or composite. Poles can also include guy wires, pole top caps and signs attached to the pole. A push brace pole on the other hand is a subtype of poles.

Tower (Norwegian term “tårn”): Towers are part of a line support and is a steel or concrete structure to carry conductors, insulators and ground wires. Towers include Cross arms.

Cross arm (Norwegian term “travers”): Cross arm is part of line supports and is the horizontal structure on or near to the top of a mast, which supports the insulators/conductors and other electrical equipment. In a tower, it is a part of the tower structure itself.

Foundation (Norwegian term “fundament”): Foundations are part of a line support and are usually one large block of concrete, or multiple blocks of concrete, where line supports are fixed to the ground.

Insulators (Norwegian term “isolatorer”): Insulators are part of a line support and isolate conductor voltage from cross-arm or tower. Insulators can also include dampers.

Platform (Norwegian term “plattform”): A platform is a horizontal structure mounted in a mast, for personnel to stand on when performing work on the equipment in the mast (fuse replacement etc).

Pole supports (Norwegian term “Barduner/stag”): A pole can be made more fixed and mechanical stable by guy-wire or similar equipment. A guy-wire, guy-line, or guy-rope also known as simply a guy, is a tensioned wire designed to add stability to a free-standing structure. Other types of equipment are cross braces (fixing poles to other poles or poles to structures/ground) and anchors (fixing guy wires to the ground). Asset types: Guy wire (“Bardun”), Anchor («Jordanker»), Cross Brace («Stag»)
