Article summary

B measure

The B measure indicates the horizontal location of a duct in a conduit as measured from its left side.

Digitizing

Objects are created in electronic format by digitizing them, meaning location information is created using a computer application.

Geometry

The geometry data of an object means the coordinate points and information on the geometric shape (point, line, area, or a group of such shapes).

H measure

The H measure indicates a duct’s vertical location in a conduit, as measured from the ground level. In other words, the H measure is a negative figure.

Search criterion

A search criterion is an attribute value that is entered on a form or selected in a menu and then used for searching for a specific object type in the database. You can use one search criterion, such as an address, or several, such as the material and installation year of a cable.

Object

Objects that can be located on the map, such as telecom premises, splices, poles, areas, exchange/telecom areas, annotations, and text.

Field

Reserved space on forms for entering property values, such as an identifier or a comment.

Centering the map

When an object is located on the map, it is used as the map center. The map is also zoomed in to the object.

Object layer

Objects on the map view are presented on various layers. For example, conduits and cables are on their own layers, as are items such as addresses, land survey objects, and annotations. Object layers can be activated and deactivated as required for various purposes.

Coordinate

Coordinates indicate an object’s location on the earth or in a map coordinate system. Map coordinates are coordinate values, and in a projected coordinate system they are defined as X and Y values, meaning the northing and easting.

Zooming out

Changing the map view so that it covers a larger area. In other words, zooming out changes the map scale so that it is smaller, and the map objects are, therefore, displayed in smaller size.

Form

Network objects are created, viewed, and edited on forms. Forms are used for creating an object on the map and for adding property values to the object. There is a separate form for each network object, and objects are managed using these object-specific forms. See also Property value.

Form button

At the bottom of each form, there are buttons for managing the object, and the functions of these buttons are similar on all forms. The buttons can be used, for example, to locate an object, update object data or geometry, or delete an object from the database.

Zooming in

Changing the map view so that it covers a smaller area. In other words, zooming in changes the map scale so that it is larger, and the map objects are, therefore, displayed in a larger size.

Scale

Scale indicates the proportion of the object representation’s size to the actual object. Maps are scaled when the objects are too small or large to be presented life-size.

Default values

Default values are an object’s property values that have been defined in the system. They are pre-completed on a form, or they can be restored to a form from the system. Default values defined in the system can include, for example, the most common property values for an object.

Property value

Property values provide information on an object’s properties, such as what the object is or what it is like. The property values of objects can be edited on forms. For example, information on an object’s construction year or address can be added.

PDF document

Printouts and some reports are created as documents in PDF format that are opened in a new browser window. These documents can be saved or printed using the browser’s printing tools. PDF documents saved on a workstation can be opened using a program such as Adobe Acrobat Reader.

Point object

A point object refers to an object called a Point object, or it can mean network objects whose location is indicated with one coordinate point. Examples of such objects are splices, telecom premises, manholes, and photos.

Location information

Location information refers to information on a geographical location defined based on coordinates, address, or other location data (such as an area name). The location of objects can be indicated in various ways. For example, an object may have been created on the map, in addition to which its address has been defined.

Database

A database is a collection of data. Data has been organised so that it can easily be managed, and the required information can be found quickly. The data in a database has been organised in a specific logical way, in order to make data retrieval as efficient as possible.

Identifier

Each network object is assigned a unique identifier. Even though objects may have identical property values, they can be identified based on their identifier.

Type

Network objects are managed on object-specific forms, such as the form for splices or the form for conduits. More detailed type information can be added to each object’s property values. For example, the type of pole can be defined as phone, electricity, or streetlight.

Menu

Reserved space on forms for selecting property values based on pre-defined options. Examples of such information include location accuracy and material.

Line object

Network objects whose location is defined using at least two coordinate points are line objects. Cables and conduits are examples of such objects.
