Summary

ATTENTION: Make sure your automated translation is disabled in your browser.

The ICEG Cables and Pipes application profile shows how terms from the associated vocabulary should be used to describe cables and pipes/ducts. This application model is based on the IMKL Cables and Pipes Information Model.

These can be located both above and below ground. As far as the underground cables and pipes or ducts are concerned, the description is such that all elements are present that contribute to limiting excavation damage.

The model builds on INSPIRE Utility Services and models on which that model is based, mainly INSPIRE Networks.

Utilities such as cables and pipes or ducts are conceived as a network (a UtilityNetwork) in which they form linear elements, connected by point objects such as splitters, connectors, connections mounted in or on cabinets, towers, poles, etc.

Cables and pipes or ducts are collections of links in the network, UtilityLinkSets composed of UtilityLinkSequences or Links. The main types of link sets are Cables, Pipes and Ducts. Pipes and Ducts are conduits: they carry substances such as water, waste water, gas or contain Cables or other Pipes or Ducts.

The Cables class is divided into Electrical Cables and Telecommunications Cables. In Pipes, a distinction is made between OilGasChemicalsPipes, Sewer Pipes, Water Pipes and Thermal Pipes.

The point objects that realize the connections in the network (For example couplings, connections, pumps, meters) are the nodes of the network, the so-called Utility Nodes. They can stand alone but are typically mounted on larger sized point objects such as Poles or Towers or sit in Cabinets on the street. We call these Utility Node Containers.

Some Utility Elements together form a facility or installation that can be separately described as an Activity Complex.

The model includes various supporting classes and data types, including to supplement the network information with topographical information (class Topographic Element) or zones where digging is not allowed (class Protected Area) or to annotate the objects (class Annotation).

The geometry of cables and pipes and nodes in the network can be described in 2D or 2.5D.

If 2.5D is not possible or is insufficient, additional information about the VerticalPosition can be provided, both relative (to a Reference Surface) and absolute (Direct Position in a vertical coordinate system such as TAW). This information is important to avoid excavation damage.

Properties
For this datatype the following properties are defined: color.
Property Expected Range Cardinality Definition Usage Codelist
color Color Value 1 The color of the object.

Curve

Definition
A 1-dimensional geometric primitive.
Usage
Dimension is to be understood in a mathematical sense: the minimum number of coordinates needed to represent any point that is part of the primitive. In the coordinate system formed by a Curve itself, 1 coordinate suffices to locate a point on the Curve, For example the distance along the Curve from the starting point. A Curve has a length but no width or height, which does not prevent it from meandering through 3D space. Curves are usually represented by polylines, which are sets of successive points where the intermediate points of the Curve are obtained by interpolation. If the interpolation method is linear you get a Linestring (an angular line connecting successive points by a straight line), other ways of interpolating result in circular arcs, cubic splines, Bézier curves etc (where the control points are not necessarily on the Curve). A Curve is bounded by its starting and ending points.

For this datatype the following properties are defined: uom.
Property Expected Range Cardinality Definition Usage Codelist
uom UOM Length 1 Unit in which the Length is expressed. For example meters, centimeters.

Location

Definition
Indication of a geographical position, by means of coordinates, a toponym, an address label, a reference to a place/region, an address or another geographical object.
Properties
No properties have been defined for this datatype.

Measure

Definition
A measured amount of a certain quantity, expressed in some unit.
Properties
For this datatype the following properties are defined: uom, value.
Property Expected Range Cardinality Definition Usage Codelist
uom Unit of Measure 1 Unit in which the quantity is expressed.
value Number 1 The amount.

Number

Definition
Indication of a quantity.
Usage
NOTE: Substitute for the primitive data types that can be used to represent a quantity. See xsd data types Integer, Float, Decimal, Double etc.
Properties
No properties have been defined for this datatype.

Point

Definition
A 0-dimensional geometric primitive.
Usage
Dimension is to be understood in a mathematical sense: the minimum number of coordinates needed to represent any point that is part of the primitive. In the coordinate system formed by a Point itself, no coordinate is needed, as there is only 1 point. A Point therefore has no width, length or depth. ATTENTION: this does not mean that a Point cannot have coordinates in another coordinate system, For example xyz-coordinates in and 3-axis orthogonal coordinate system.

Reference Surface

Definition
Surface relative to which a position is measured.
Usage
In this context typically the ground level.
Properties
For this datatype the following properties are defined: location, type, vertical position.
Property Expected Range Cardinality Definition Usage Codelist
location Geometry 1 Location of the Reference Surface. Typically the xy-coordinates of a Point on the earth's surface for which the Vertical Position of the Reference Surface applies. Or the Geometry of (part of) the Reference Surface.
type Reference Surface Type 0..1 The type of Reference Surface. Typical the groundlevel.
vertical position Direct Position 0..1 The Vertical Position of the ReferenceSurface as position in a vertical coordinate system. Typical the groundlevel.

Survey

Definition
Determining the exact size of something by measuring it.
Properties
For this datatype the following properties are defined: accuracy, date, method, recorded by.
Property Expected Range Cardinality Definition Usage Codelist
accuracy Positional Accuracy 0..1 The Positional Accuracy of the Survey.
date DateTime 0..1 The moment at which the Survey took place.
method Method of Measurement 1 Type of the method used.
recorded by Agent 0..1 Agent who carried out the Survey.

Vertical Position

Definition
Position in vertical direction relative to a Reference Surface.
Properties
For this datatype the following properties are defined: distance, location, reference surface, vertical position.
Property Expected Range Cardinality Definition Usage Codelist
distance Measure 0..1 The Vertical Position as distance from the Reference Surface. For example, the distance from ground level.
location Geometry 0..1 Location for which the Vertical Position applies. Typically the xy-coordinates of a Point on the earth's surface for which the Vertical Position of the Reference Surface applies. Or the Geometry of (part of) the Reference Surface.
reference surface Reference Surface 1 Reference to the Reference Surface. For example, the ground level.
vertical position Direct Position 0..1 The Vertical Position as a position in a vertical coordinate system. For example, in Belgium the z-coordinate in TAW.
