The Morphology of Public Open Spaces as Visual Opportunity Fields A space syntax approach based on Revelation and VGA maps customization with SalaScript

Abstract

This paper explores the visual dynamics of the morphology of public open spaces.Resorting to space syntax concepts, visual graph analysis (VGA), and the innovative use of its standard tool Depthmap, a set of case studies is analysed under the perspective of visual opportunity fields and building upon the established concept and metrics of Revelation. A series of related novel measures and visualizations are developed, which are only possible, in Depthmap environment, by the advanced use of its scripting language: SalaScript. Despite Depthmap being the standard tool among the space syntax community, there is a lack of references to the explicit use of SalaScript. One major objective of this paper is to illustrate, and document, its possibilities to a broad audience by extending, customizing and introducing a more interactive approach in handling VGA maps. We present SalaScript functionalities and its use in the development of visual analysis scripts that allow the study of revelation, which we then apply to a set of real public open spaces case studies.

“…In the next step, using the rotated component matrix table, the number of extracted categories and the concepts that define each of these factors could be discovered (Table 4). Consequently, the boundary commonalities in houses number 38,33,35,39,43,42,34,32,44,45,37,31,40,30,29,17 and 41 define the first category. Houses number 28,26,22,27,20,18,19,16,23,25,24, and 21 are the second category, houses number 9, 5, 11, 15, 14, 1, 13, 3, 8, 7, 4 and 12 form the third category and houses 10 and 2 form the fourth category.…”

“…In the study of residential spaces in Iranian research, factors such as integration, entropy, visibility, and access have often been analyzed graphically using Depth Map [11][12][13][14]. In international articles, Depth Map is mostly used for urban space analysis [15][16][17][18][19][20][21]. In cases where residential spaces are analyzed, either as a subjective analysis or using A Graph and Depth Map, the level of integration, visibility, and hierarchy of spaces' interaction is presented in the form of colored diagrams [22][23][24][25].…”
