“…How to assess whether or not a portion of terrain is visible is an ongoing subject of research (Klouček et al 2015, Nutsford et al 2015, Sahraoui et al 2018, Abdulhafedh 2019, Fábrega-Álvarez and Parcero-Oubiña 2019, Palmer 2019, Saeidi et al 2019, Mancini 2020). In fact, for survey activities, visibility (line of sight) is not sufficient if the objects of the survey are too small, too distant, or oriented in such a way that they cannot be perceived and/or mapped.…”

“…The illustrated examples in Section 5 describe the informative content of the products of r.survey. The NumberOfViews map (Figure 9(g)) provides information on the number of viewpoints a target is visible from; this is an issue relevant to fields such as visual impact assessment studies (Shang and Bishop 2000, Joly et al 2009, Palmer 2019, Saeidi et al 2019. PointOfView* maps allow identification of the position with the best visibility (maximum solid angle), the most frontal view (maximum view angle), or the nearest location (minimum 3D distance) with respect to a given target (Figures 9 and 10).…”

“…Terrain survey includes detection and measurement of surfaces, and can be conducted over large areas using simple visual observation or remote sensing via instruments such as laser scanners or optical, infrared and radar sensors. It is a key part of many scientific disciplines including geomorphology, biology, biogeography, archeology, landscape studies, and civil engineering (Santangelo et al 2010, Edan et al 2013, Minelli et al 2014, Fábrega-Álvarez and Parcero-Oubiña 2019, Saeidi et al 2019. In this regard, visual observation of terrain, either directly or through photo interpretation, has been one of the most widely used approaches.…”

Identification of terrain surface features can be done using approaches such as visual observation or remote sensing image processing. Accurate detection of survey targets at the ground level primarily depends on human visual acuity or sensor resolution, and then on acquisition geometry (i.e. the relative position and orientation between the surveyor and the terrain). Further, the delimitation of the observer's viewshed boundary or of the sensor's ground footprint is sometimes insufficient to ensure that all enclosed targets can be correctly detected. Size and orientation can hamper ground target visibility. In this paper we describe a new release of r.survey, an open-source spatial analysis tool for terrain survey assessment. This tool offers the necessary information to assess how terrain morphology is perceived by observers and/or sensors by means of three basic visibility metrics: 3D distance, view angle, and solid angle. It is also fully customizable, allowing single or multiple observation points, ground or aerial point of view, and size setting of the observed target, making it useful for many different purposes.

“…These indexes include landscape metrics such as landscape structure indicators (Cook, 2002), landscape network connectivity indexes (Saura et al, 2011), open area indexes, habitable area indexes (Bölen et al, 2011) or vegetation surface width, distribution density (Liu et al, 2016), and weighted fractal indexes (Zhao et al, 2014). In addition to these, it is seen that indicators such as public space quality indexes (Siregar, 2014), visibility analyses, visual impact assessments (Saeidi et al, 2018), and urban landscape quality indexes (Gavrilidis et al, 2016) are used in examining the relations between public uses and their physical components. However, it can be said that these approaches focus on a singular main criterion and its sub-criteria clusters.…”

The research presents a multi-criteria decision-making method that focuses on evaluating spatial performance by considering all areas without roads or structural elements as "urban surfaces". In this context, the Seyyid Ömer neighbourhood in Istanbul's Fatih district, as the study area, was discussed in detail in terms of physical, ecological, and social criteria and their sub-criteria. While the physical criteria include the size of each area and enclosure; the ecological criteria were studied with permeability rates and the normalised difference vegetation index (NDVI) value, which measures unit area through the amount of chlorophyll. In addition, the type of property and land use in the urban context, which are the main factors for citizens' interaction with open spaces, were included as sub-criteria under the main social criterion. The relationships between the identified criteria and the open space typologies in the neighbourhood were converted into an index using the analytical network process (ANP) to measure the urban surface performance. The developed index indicated that some urban voids stand out even more than the important ones and have greater potential than urban parks such as Çukur Bostan in terms of social and vegetation qualities. As a result of the research, a map of the importance level was created to illustrate the potential areas for improving the urban ecological performance. Then, various pocket parks such as Şelaleli Park and Skate Park and urban voids regarding their physical, ecological and social values were extracted as potential urban open spaces. With this structure, the research proposes a multi-criteria index that can be used to evaluate the potential of urban surfaces by putting them on a multi-dimensional and computable scale.

“…Besides traditional maps produced by cartography, the digital version of such maps are managed by means of GIS, and their 3D versions, the 3D city models. Geoinformation plays an essential role in the analysis of a city [39,40,41,42,43] and could be effectively used in the assessment of the reciprocal impacts of the new construction and the city.…”

Growing interest is awarded to the digitalization of the building permitting use case and many works are developed about the topic. However, the subject is very complex and many aspects are usually tackled separately, making it very hard for traditional literature reviews to grasp the actual progress in the overall topic. This paper unveils the detailed state of the art in Digital Building Permitting (DBP) by critically analyzing the literature by means of a set of coding tags (research progress, implementation, affected DBP workflow steps, ambitions addressed) assigned by a multidisciplinary team. The mainly addressed aspects of the digitalization of building permits resulted to be the technologies to check the compliance of design proposals against regulations, followed by the digitalization of regulations. Lacking aspects are instead the involvement of officers, scalability of solutions and interoperability of data, intended both as data validation and as integration of geoinformation with building models.
