“Urban design has formed a field in which visual-spatial, cultural, social, functional and natural factors are taken into account for the purpose of providing the best habitat, and that gathers multidimensional concepts together within time while being developed in the intersection of architecture and city planning. Urban design has a wide range of content developed in communication with various disciplines. Within its content, computer and mathematical based model suggestions, especially on researches where urban environment qualities are examined, contribute to the discipline as innovative approaches.

Entropy approach has been put forward as an applicable innovation approach in the matter of aesthetic evaluation (see: beauty) in urban design. Entropy, aesthetic and urban design concepts have some relations. Entropy, in its preliminary meaning, is the mathematical representation of thermodynamic results. In its second sense as used in definition of the relation between entropy urban design and aesthetics, it refers to the concept for measuring the quantity of information within a system. Measuring the entropy is related to the distribution of positional figures of a message or information from the probabilities standpoint. Formal aesthetic evaluation criteria which are using in evaluating the aesthetic value of a designed space that can be taken into consideration in the entropy methodology must have the appropriate qualifications to join numerical procedures.

In applications, distribution relations of formal aesthetic evaluation criteria are measured over aesthetics-related evaluation concepts. The aesthetical qualities of the city are considered at different scales such as urban pattern, urban skylines, cityscapes, city squares and urban furniture. From among these scales, urban skylines are preferred for the applications. Aesthetical evaluation of the cities, measurability can be achieved through the entropy method. This method also makes possible an interrogation into the relationship that urban skylines formal esthetic evaluation criteria have established between each other.”
