Abstract |
The Dutch spatial planning legal act of 2008 was aimed at improving efficiency and effectiveness in the development, evaluation and monitoring of spatial planning policy (Ministry of VROM, 2006a). One of the main effects of this legal act was the widespread availability and use of digital spatial plans (Ministry of VROM 2006a, b). This reform led to the expectation that all digital spatial plans would be exchangeable and comparable. In practice, this exchange and comparison required carrying out complex procedures due to uncertainty caused by differences in the scope of spatial plans as well as their intended use. Furthermore the uncertainty resulted in a lack of confidence in spatial plans by policymakers and supporting GIS staff. Our overarching research question was: how can uncertainty caused by incomplete geo-information sources be dealt with? We proposed two techniques—fuzzy logic and visualisation—for policy makers to deal with uncertainty resulting from incomplete geo-information sources in spatial planning at the regional and national planning levels. We used two case studies in the Netherlands to illustrate the results of applying these techniques. The fuzzy set theory provides extra information by converting the discrete borders of continuous objects into fuzzy borders that improve the resemblance to the real object and thus make it more realistic. As shown in the second case study, visualisation also improves the degree of realism and thus provides additional information. Both case studies showed that providing additional information reduces the uncertainty felt by policymakers. |

Abstract |
This paper investigates the effects and affects of darkness, a condition that is progressively becoming less familiar for those of us in the over-illuminated West. In countering the prevailing cultural understanding that darkness is a negative condition, I draw attention to other historical and cultural ways of positively valuing darkness. Subsequently, in drawing on two sites, a gloomy landscape at a dark sky park in South Scotland, and a tourist attraction in which a simulation of New York is experienced in a completely dark environment, I explore the multivalent qualities of darkness. In foregrounding the becoming of sensory experience in gloomy space, I highlight the mobilisation of alternative modes of visual perception in as well as the emergence of non-visual apprehensions, and suggest that the potentialities of darkness might foster progressive forms of conviviality, communication and imagination.
Cet article interroge les effets et les affects de l'obscurité, une condition qui devient de moins en moins courante pour ceux parmi nous dans l'occident sur-illuminé. Pour s'opposer à la compréhension culturelle dominante que l'obscurité est une condition négative, j'attire l'attention aux autres façons historiques et culturelles de faire valoir l'obscurité. Ensuite, en tirant de deux sites—l'un, un paysage sombre à un parc de ciel obscure dans l'Ecosse du Sud, et l'autre, une attraction touristique dans laquelleon a une expérience d'une simulation de New York dans un environnement complètement noirci—j'examine les qualités polyvalentes de l'obscurité. En mettant en premier plan l'émergence de l'expérience sensorielle dans l'espace sombre, je souligne la mobilisation des modes alternatives de la perception visuelle ainsi que l'émergence des appréhensions non-visuelles, et je suggère que les potentialités de l'obscurité puissent encourager des formes progressives de la convivialité, la communication, et l'imagination.
Este artÃculo explora los efectos y los afectos asociadosa la oscuridad, una condición que resulta cada vez menos familiar para aquellos de nosotros que vivimos en unOccidentehiperiluminado.A los fines de contrarrestar la perspectiva cultural predominante que le asigna a la oscuridad una valoración negativa, pretendo llamar la atención sobre otras formas históricas y culturales que le otorgan un valor positivo a la oscuridad. Luego exploro las cualidades polivalentesde la oscuridad mediante el estudio de dos sitios: el paisaje sombrÃo de un parque sin iluminación artificial en el sur de Escocia y una atracción turÃstica en el que se simula la ciudad de Nueva York, experimentada en un ambiente completamente oscuro.A los fines de dar cuenta del desarrollo de experiencias sensoriales en espacios sombrÃos, destaco la movilización de modos alternativos de percepción visual asà como también la emergencia de formas de aprehensión no visuales Además,sugiero que la oscuridad tiene el potencial para promoverformas de convivencia, comunicación e imaginación progresistas. |

Abstract |
The angular distribution function of light emitted from cities is unknown, and represents the most important systematic error in skyglow simulations. We describe a method for measuring this distribution using a two camera system mounted on an aerial platform. We present preliminary results from a test flight using such a system, taken over the city of Berlin on July 14, 2011. |
