Analysis and classification of open public spaces, a method using perception and measurable indexes

This paper addresses the complexity of contemporary public space types. We suggest a method of urban analysis that systematizes ways of identifying sensitive and spatial characteristics present in open public spaces, in the urban landscape of the city of Fortaleza, Brazil. The morphology and organization of these spaces implies a social structure and relationships that infer affection, and a possible measure of spatial quality. The morphological analysis is supported both by Spatial Syntax research and information technologies such as Geographic Information System platform, bringing 3D tools for urban analysis through information modeling. To analyze the dimensions of the space quality that improve everyday usage, authors like Lynch, Cullen, Gehl and Jacobs are inspirational for the creation of parameters and variables of life in the city. In addition, we suggest a more attentive format of perception of urban poiesis using sketchbooks, a tool explored by Salavisa. As a result of this investigation, starting from the phenomenological study, we seek to present a model of space analysis. Said model connects sensitive aspects of human perception and the abstract and rational approach, formalized in indicators that can be quantified.
