“…To survey this urban fragment, we have chosen a 1.6 km pedestrian route (see Figure 1b) that winds its way from the medieval district in the east to a district of classical architecture dating back to the 18 th and 19 th centuries in the west. A research study conducted in 2010 on this same route [11] showed that its direction, if it is perfectly explained from a chronological point of view, is perfectible in terms of better visibility of heritage objects. For obvious reasons related to the constrained size of this article, the illustrations we present from now on are limited to a small portion of this path (from sampling point #30 to sampling point #40, see Figure 1b).…”

. The graphical representation of a complex polygonal object, such as an isovist field (i.e. a 2D isovist in its evolution over time along a pedestrian path in an urban environment) is a hard research issue that was stated in the late 1970s by Benedikt [1]. The generalized space-time cube from Bach and al. [2] is a conceptual framework allowing to propose innovative implementations for the analysis and the display of this complex object. The purpose of this article is to situate, within this formal framework, all the graphical representation solutions that have already been developed for isovist fields. It also aims to identify the problems raised by each of these solutions (spatial anchoring, arbitrary sampling, etc.) and to propose related solutions.

“…The analysis technique is to conduct the building silhouette extraction and building appearance segmentation of each building sample from different observation areas. Some researches related to the visibility evaluation have been performed, such as the visibility evaluation on historical buildings [4,5], urban environments [6], and indoor environment [7]. There are various methods used in such studies such as taking a photo of each building and examine the architectural elements affecting visual perception through an empirical analysis, using a visibility analysis tool for 3D urban environments to analyze the visibility of facade surfaces [6], implementing isovist method [5,7] and conducting a sequential photo mapping [4].…”

Lastly, the evaluation of visual continuity executes the sequential photo mapping due to having the several benefits such as only capture a shorter period of data collecting and analysis since the technique does not need complicated phases and specific computational skills.…”

The expansion of shopping centers has become an issue of interest in the formation of a transitional space between the shop fronts with a public area. Shopping facilities are expected to accommodate the continuity of motion and good visual on spaces that transition with the surrounding environment. The purpose of this study was to determine the typology forms a transitional space in the front area of the shop building in the shopping center as well as knowing the quality of the visual aspects of continuity of motion-transition space in the front area of the shop building in a shopping center in Malang City. Character formation of transitional space in the shop front has encouraged the emergence of various types and scales of territorial between private space and public space, both physically and psychologically. Building frontage or shop fronts have a high degree of transparency to the area of the road, which can present the appearance of the expansion and territorial psychological. A study of motion-visual continuity transition space in the shopfront of the shopping center utilized a field observation and a sequential photo mapping method. This study analyzes the typology of shop front space and the continuity of visual. The results of this study concluded that the typology forms a transitional space in the front area of the shopping building in the shopping center in Malang, and is inserted interface type that has a good quality of motion-visual continuity on aspects of proximity, similarity, continuity, and closure.

Abstract. Partial isovists fields are useful methods to analyze the urban morphology taking into account the visual perception of the pedestrian. However, as previous studies involve a constant visual aperture angle all along the pathway, this paper presents an adaptative method of aperture angular variation according to urban morphology properties. Aperture angle increasing, nearby a square or at roads junction, or decreasing within a canyon street should improve the micro-behavior visual perception in our simulations. With showing that traditional isovist's shape indicators are not well adapted to achieve urban environmental properties, the aim of this paper is to present this new methodology based on a statistics standardized moment called Kurtosis. Our results show that this method could be used to define a surrounding space typology, one step more towards the modeling of visual dynamics.
