Neatline

A border line commonly drawn around the extent of a map.

Network

  1. An interconnected set of arcs representing possible paths for the movement of resources from one location to another.

  2. A layer representing linear features containing arcs or a route-system. Also known as network layer. 3. When referring to computer hardware systems, a local area network (LAN) or a wide area network (WAN).

Network Trace

Navigates a network following connectivity defined by the geometric network. Specific kinds of network traces are: Trace upstream, Find connected, Find loops, Find common ancestors, Trace downstream.

Node

The beginning and ending locations of an arc. A node is topologically linked to all arcs that meet at the node.

Node Type

Indicates the format you are using in your process management module. Session Manager typically has only one node type called "session." Workflow Manager has two node types: "work request" and "design."

Non-GIS CU

Non-GIS CUs are not associated with a feature or object class and do not have spatial representation on the map (e.g., alley arm, anchor arm, cluster mount, pole assembly).

Non-Symbolized CU

A non-symbolized CU has no shape on the map, but is associated with an object class. e.g., transformer unit, conductor unit.

Null Value

The absence of a value. If a particular column of a row in a table is null, that means there is no value stored. Null is not the same as blank or zero.
