Impedance

The amount of resistance (or cost) required to traverse a line from its origin node to its destination node or to make a turn (i.e., move from one arc through a node onto another arc). Resistance may be a measure of travel distance, time, speed of travel times the length, and so on. Higher impedance indicates more resistance to movement, with 0 indicating no cost. Often, a negative impedance value indicates a barrier. Impedance is used in network routing and allocation. An optimum path in a network is the path of least resistance (or lowest impedance).

In Construction

State for a work request during which construction is performed in the field. While a work request is In Construction, its approved design is updated with As-Built changes. After the As-Built changes, the design is verified, and the work request is completed.

In Design

State for a design and a work request. A design that is In Design is owned by a Designer who may edit it in ArcMap. A work request that is In Design has at least one design that is In Design or Pending Approval, but no designs that have been Approved.

Initiated

State of a work request in which it has been created, but no design has yet been associated with it.

Inset Frame

An inset frame is a map element which is placed in the Layout view and shows a user-specified feature in the Layout view. Each inset frame shows one feature.
