Subdivisjon

Subdivisjon is a term used to describe the act of dividing something larger into smaller parts, or the resulting parts themselves. The word is used in several languages, including Norwegian and Danish, and derives from Latin sub- meaning “under” and dividere meaning “to divide.” In practice, a subdivision is often defined by its relationship to a larger entity, while retaining its own distinct boundaries or properties.

In mathematics and computer graphics, subdivision refers to procedures that create finer representations from coarser ones. For example, subdividing a polygon or a curve produces more vertices and smoother shapes. Subdivision surfaces, such as Catmull-Clark or Loop schemes, are widely used to generate smooth 3D models from simple meshes. In this context, subdivision is a method for refining geometry while preserving overall form.

In urban planning and real estate, a subdivision describes the division of land into plots or parcels for development or sale. This process involves surveying, legal documentation (such as plats or deeds), and compliance with zoning, infrastructure requirements, and environmental regulations. The resulting subdivisions define street layouts, utility access, and lot sizes, shaping residential, commercial, or mixed-use communities.

In administrative geography, a subdivision denotes a smaller political or administrative unit within a larger region—such as districts, counties, or boroughs—used for governance and organization of services.

In music and timekeeping, subdivisions refer to the division of beats or time into smaller, evenly spaced units, enabling precise rhythm and tempo.
