Urban Waterfront Data Analysis

(O. B. Moraes & Abiko, 2008; O. B. d. Moraes, 2007). Use of these standard methods lead to loss of numerous information and inaccurate evaluations. The urban waterfront includes the complex walkability term which implies many different physical, social and technical properties, as assembled in table 1, and confronts continuous evaluation and decision making processes. All of their indicators contain ambiguity, impreciseness, and uncertainty in their data. Specifically, there are two problems in dealing with information of a typology like this, first it involves subjective, uncertain or ill-identified concepts, and second, it is represented in qualitative scales of measurement and there are a limited number of methods for managing these types
of scales, for example, terms like accessible, distance, homogenous, singularity, contrast, or the like.
