Building Project

This article presents a GIS-aided visibility and dominance analysis used for a visual-impact assessment of a planned high-rise building located in a central area in Trondheim, Norway. The visibility analysis calculates fields of intervisibility between the high-rise building and locations in the urban landscape. Visual obstacles such as existing buildings and trees are included. The dominance analysis adds to the visibility analysis a measure of how visually dominant the high-rise building would be. The dominance measure is based on the distance to the building and how much of the building would be visible from any observation point. The result is an assessment of visibility and dominance throughout the entire study area as opposed to using photomontages for assessing visibility and dominance from single standpoints.

The Relationship

The visual sensation is an important factor in urban planning. A computer analysis technology based on the three-dimensional Geographical Information Systems (3DGIS) can be used to measure the visibility in urban space. The principle of sight calculations is introduced at first. The visibility analysis models about terrain and buildings are proposed. In terrain visibility analysis, a method based on projection and elevation interpolation is used to calculate the visibility of two points. And in building visibility analysis, another projection method is proposed to judge the relationship between the sight and building. Based on the visibility analysis of two points, an approximate visual field in a plane can be computed in a discrete way. The visibility analysis models are proved to be feasible. Further research that combines the visibility analysis model and the quantitative planning targets is suggested.

The City

As destination of choice for many short-term study abroad programs, Berlin offers students of German language, culture and history a number of sites richly layered with significance. The complexities of these sites and the competing narratives that surround them are difficult for students to grasp in a condensed period of time. Using approaches from the spatial humanities, this article offers a case study for enhancing student learning through the creation of digital maps and itineraries in a campus-based course for subsequent use during a three-week program in Berlin. In particular, the concept of deep mapping is discussed as a means of augmenting understanding of the city and its history from a narrative across time to a narrative across the physical space of the city. As itineraries, these course-based projects were replicated on site. In moving from the digital environment to the urban landscape, this article concludes by noting meanings uncovered and narratives formed as we moved through the physical space of the city.

Aquarelles parisiennes: Gautier, Baudelaire, and the Poetry of Urban Watercolours

Fleurs Du Mal

Baudelaire refers in his first essay on Théophile Gautier (1859) to the ‘fraîcheurs enchanteresses’ and ‘profondeurs fuyantes’ yielded by the medium of watercolour, which invites a reading of his unearthing of a romantic Gautier as a prescription for the ‘watercolouring’ of his own lyric. If Paris's environment was tinted black as a spiking population and industrial zeal made their marks on the metropolis, Baudelaire's washing over of the urban landscape allowed vivid colours to bleed through the ‘fange’. In his early urban poems from Albertus (1832), Gautier's overall tint of an ethereal atmosphere as well as absorption of chaos and din into a lulling, muted harmony establish the balmy ‘mise en scène’ that Baudelaire produces at the outset of the ‘Tableaux parisiens’ (Les Fleurs du mal, 1861). With a reading of Baudelaire's ‘Tableaux parisiens’ as at once a response and departure from Gautier, or a meeting point where nostalgia ironically informs an avant-garde poetics, I show in this paper how Baudelaire's luminescent and fluid traces of color in his urban poems, no matter how washed or pale, vividly resist the inky plumes of the Second Empire.

The City

Writers of the early nineteenth century sought to find new ways of writing about the urban landscape when first confronted with the phenomena of London. The very nature of London's rapid growth, its unprecedented scale, and its mere difference from any other urban centre throughout the world marked it out as demanding a different register in prose and poetry. The condition of writing the city, of inventing a new writing for a new experience is explored by familiar texts of urban representation such as by Thomas De Quincey and William Wordsworth, as well as through less widely read authors such as Sarah Green, Pierce Egan, and Robert Southey, particularly his fictional Letters from England.

The design of every aspect of the urban landscape—from streets and sidewalks to green spaces, mass transit, and housing—fundamentally influences the health and safety of the communities who live there. It can affect people's stress levels and determine whether they walk or drive, the quality of the air they breathe, and how free they are from crime. This book provides a compelling look at the new science and art of urban planning, showing how scientists, planners, and citizens can work together to reshape city life in measurably positive ways. It demonstrates how well-designed changes to place can significantly improve the well-being of large groups of people. The book argues that there is a disconnect between those who implement place-based changes, such as planners and developers, and the urban scientists who are now able to rigorously evaluate these changes through testing and experimentation. It covers a broad range of structural interventions, such as building and housing, land and open space, transportation and street environments, and entertainment and recreation centers. Science shows we can enhance people's health and safety by changing neighborhoods block-by-block. The book explains why planners and developers need to recognize the value of scientific testing, and why scientists need to embrace the indispensable know-how of planners and developers. It reveals how these professionals, working together and with urban residents, can create place-based interventions that are simple, affordable, and scalable to entire cities.
