In network analysis, an entity that prevents flow from traversing a network edge or junction.
A line feature used to keep certain points from being used in the calculation of new values when a raster is interpolated. The line can represent a cliff, ridge, or some other interruption in the landscape. Only the sample points on the same side of the barrier as the current processing cell will be considered.
For geometric networks in ArcMap, a temporary graphic that is placed on the network, past which a trace cannot continue.
For geometric network datasets in ArcMap, a network location in a network analysis layer that restricts the traversability of a network element (edge or junction) in the network dataset.
