nodes

1. In network analysis, destinations or intersection points which are part of a network. These are also known as vertices.

2. In behavioural urban geography, the strategic points in a built-up area around which the individual plans his or her movements.

3. In Geographic Information Systems, the start- or end-point of a line or link.

A nodal region exhibits links between its separate parts and one or more central points. It is usually defined through the use of flow data.
