The relationship between the material settings and situational belonging to a more general notion of the culture of a given community remains the subject of inquiry of at least two scientific disciplines: anthropology and urban morphology studies. In this study an assessment of the various modelling platforms is performed with the objective of finding the most efficient method which allows the description of the semiotic features of urbanscapes. The ideal system should link the parametric definition of urban geometry with the high flexibility of data input and easy manipulation. In order to enable culture related analyses of urbanscapes, analyses should be performed which refers to the semiotics of morphological structures in the detailed scale of urban enclosure, which are streets or squares. Some elements of the proposed method of index key analyses are explained as one possible solution for the problems posed.
