impact of urban shapes on urban planning (the case study, borujerd city, iran)

this paper is concerned with a methodology that is able to recognize and classify geometric shapes, in particular urban shapes. the main objective of this study is to develop a shape index that will address whyte’s category of “‘spatial form” (1 968), that is, the external appearance or outward form, in contrast with the “‘internal form,” which is the structural form. we first review methodologies of shape recognition and classification. next, we propose a viable formulation for such an endeavor by drawing from the aforementioned methodologies, and we aim to overcome some of their limitations by formulating a new index. we will apply the resulting shape index to an illustrative case in order to recognize urban shapes.
