Comparing Semantic and Semiotic Indices in Visual System Focusing on Identity Formation (Case Study: Fahadan and Posht-e Bagh Comparison)

City as a combination of natural and social factors and environments recognized by human in which a resident population has been centralized has a special identity. An identity has distinguished city from other cities and gives meaning to the population residing in it, identity in the appearance of environments built by humans is always taken from the parameters of human and behavioral sciences that this identity is more valuable in neighborhoods with historical oldness and historical context due to more application of semantic and identity signs attributed to culture. The semantic and semiotic indices have been different from each other considering neighborhoods and their types but it seems that indices with high coefficient have been used to design the centers of these neighborhoods. This study aims at extracting variables with high coefficient in all neighborhoods to be used in the flagship development of other neighborhoods. Concurrent nested mixed research method has been used in this study that variables and indices extracted in qualitative part and compared in quantitative part, semi-structured interview used in qualitative part to explore and scrutinize variables and in order to facilitate this, Atlas. ti has been used to reduce data. The results compared in qualitative part using ORIGINPRO, sample size achieved using snowball system with theoretical saturation in qualitative part and Morgan Table used in quantitative part. The results show that all spaces are axial and central (۱.۰۰۰), specifying, explaining and defining each path (۰.۹۵۸) and inner value (۰.۹۲۱) have the highest coefficient of determination and effectiveness in Posht-e Bagh neighborhood and the least effectiveness is related to conceptual richness (۰.۲۴۶) but all spaces are axial and central (۱.۰۰۰), inner value (۰.۹۷۸) and special arrangement and order (۰.۹۲۰) have the highest coefficient of determination in Fahadan neighborhood and the least one is related to motifs taken from nature (۰.۲۵۴).
