Methods and systems for boundary delineation are described. In one embodiment, a living unit identifier may be translated into a translated geographic location point. The living unit identifier may be within a distribution area. A closed plane living unit-based figure that bounds the translated geographic location point may be delineated. An additional closed plane living unit-based figure that bounds a geographic location point may be delineated. The geographic location point may be associated with an additional living unit identifier within the distribution area. The closed plane living unit-based figure and the additional closed plane living unit-based figure may be merged to create a distribution area figure of the distribution area. Additional methods and systems are disclosed.
