[visualization techniques, spatial analysis]
A line in a TIN that represents a distinct interruption in the slope of a surface, such as a ridge, road, or stream. Breaklines function as edge constraints: no triangle in a TIN may cross a breakline. Z-values along a breakline can be constant or variable.
