Routes are important operative structures in landscape architecture because they play a crucial role in mediating or facilitating the use and reception of (designed) landscapes. Routes are the ‘silent guides of the stroller’ and facilitate the primordial act of walking as an aesthetic and social practice. The shape of a walk refers not only to the formal aspects of routing such as the tracing and gradient of the routes, but also to the landscape space as people perceive it. This perceptual space indicates the visual reality, the sensorial experience that emerges only by bodily movement and is affected by topological, physical, social, and psychological conditions. The psychologist Kurt Lewin proposed in 1934 the term Hodological Space to describe these factual conditions a person is faced with on its way (‘Hodos’, a Greek word meaning ‘way’). The psychogeographical maps of Guy Debord in the 1950’s and Hans Dieter Schaal in the late 1970’s are inspiring attempts to visualize perceptual space.

Visual perception and kinaesthesia

The shape of a walk as a concept connects visual perception to the ‘sense of movement’ or kinaesthesia. In traditional Asian culture it is common to link visual perception with movement as exemplified by the Chinese character for ‘to see’ 見 in which the upper part symbolises the eye 目and the lower part symbolises the feet of a person 儿. Kinaesthetic experience involves several sensory channels for an active participation with the spatial environment. The brain integrates information from proprioception and the vestibular system into its overall sense of body position, movement, and acceleration, which is important for spatial orientation as described by the neuroscientist Alain Berthoz.

Bodily sensation and muscle movement are thus closely related to visual perception. As James Gibson elaborates in his seminal work ‘The ecological approach to visual perception’: “Locomotion is guided by visual perception. Not only does it depend on perception but perception depends on locomotion inasmuch as a moving point of observation is necessary for any adequate acquaintance with the environment. So we must perceive in order to move, but we must also move in order to perceive.” The shape of a walk is therefore determined by a kinaesthetic experience of the designed landscape where visual perception is inherently connected to one’s abilities and possibilities for movement offered by the design.

Walking as field of study in landscape architecture

The shape of the walk is thus of crucial importance in landscape architecture because it is not possible to perceive space without movement of the eye, head and body. It determines the tactile and kinaesthetic experience and is the means to organise the visual logic of a site by directing the individual’s gaze at views or focal points and their sequence. From this follows that the shape of a walk is an important unifying and structural principle in landscape design and the discovery of landscape from past to present. According to the garden theorist and historian Erik A. de Jong it must be considered the hinge that steered more than anything else the changing options for use, experience, and design and contributed fundamentally to both personal and cultural developments.

From this perspective the shape of a walk becomes a highly relevant field of study in landscape architecture. Not only in the sense that it addresses the phenomenological dimensions of landscape as proposed by the sociologist Lucius Burckhardt with his Science of Strolling (called: Strollology or Promenadology), or that it offers an alternative approach to landscape design that integrates intense space perception, encourages intuition and supports organization as elaborated by landscape architects such as Henrik Schultz and Günther Voght. The shape of a walk is also an important container of design knowledge available for systematic exploration, description and classification. It is an invaluable source of design principles that effectively shape the relation between formal space (‘space of coordinates’) and perceptual space. Studying the shape of a walk can help landscape architects to get a grip on space as perceived from eye-level, kinaesthetic aspects, wayfinding, and the phenomenology of landscape in order to become tools for landscape design.

Landscape can be defined as “an area, as perceived by people, whose character is the result of the action and interaction of natural and/or human factors” [1].This definition clearly emphasises the sensory relationship between the observer and the landscape. The major question here is: how do we know and understand the landscape through perception?

Although ‘perceived by people’ refers to a holistic experience with all senses, very often it is reduced to the visual aspects. This has to do with the fact that 80% of our impression of our surroundings comes from sight [2]. Also the ‘range’ of our senses plays an important role. Granö (1929) already made the distinction between the ‘Nahsicht’ and ‘Fernsicht’. The Nahsicht or proximity is the environment we can experience with all our senses, the Fernsicht he called also landscape and is the part of our environment we mainly experience by vision [3]. Hence the identifying character of landscapes in the rural and urban realm is, to a large extent, built upon visual perception. Since visual perception is a key factor in behaviour and preference, it is crucial for landscape planning, design, and management, as well as for monitoring and protection of landscapes. But how can we comprehend the ‘face of the landscape’ and its perception? And how can we make this applicable to landscape planning, design and management?

Can you see the face? [4]

We believe that the long tradition and current advances in the field of visual landscape research offer interesting clues for theory, methodology and applications in this direction [5]. Visual landscape research is an interdisciplinary approach that combines (a) landscape planning, design and management concepts, (b) landscape perception approaches, and (c) Geographic Information Science (GISc)-based methods and techniques. While integrating psychological knowledge of landscape perception, the technical considerations of geomatics, and methodology of landscape architecture and urban planning, it provides a solid basis for visual landscape assessment in cities, parks and rural areas. It offers great potential for the acquisition of design knowledge by exploring landscape architectonic compositions from the ‘inside out’, as well as possibilities to enrich landscape character assessment with visual landscape indicators. Since they are crucial elements in landscape perception and preference it is important for landscape planning, policy and monitoring to get a grip on visual landscape attributes like spaciousness and related indicators (e.g. degree of openness, visual dominance, building density and the nature of spatial boundaries).

The field of visual landscape research is expanding every day. Influenced by national and international initiatives it is likely to continue developing in three ways. In the first place by scientific development of theory, methods and techniques. Secondly by implementation in education, and thirdly by knowledge transfer and applications in academia and society (valorisation). In order to facilitate this development a dialogue is needed between the scientific community and society through high quality publications and platforms for knowledge dissemination and discussion. We like to contribute to this dialogue via our platform Exploring the Visual Landscape (EVL), an initiative of Delft University of Technology, Landscape Architecture andWageningenUniversity, Centre for Geo-Information.
