Water has historically played a strong role in the economic and cultural development of many great civilizations. More than ever before this continues to be the case in the twenty-first century as we witness the critical nature of water resources in developed and developing nations alike. What is unique about water in this time, however,

When the authors of the Preamble to the United Nations Convention on the Law of the Sea wrote this prescient phrase in 1982, few people recognized how relevant it would become to the marine world of today. Scientists are calling increasingly for ecosystem-based management of marine areas and considerable work has already been done on

Depleted fissh stocks, degradation of coastal and marine areas, as well as user contracts have prompted calls from the international community for an integrated approach to managing these areas. Nearly 700 initiatives in Integrated Coastal and Ocean Management (ICOM) are estimated to have been initiated in more than 140 countries since the mid-1960s (Sorensen, 2002).

Land use and land cover changes have significant impact on the environment and accordingly this topic has gained increasing political awareness during the last decade. Using modelling and simulation, we can increase our understanding of the land-use system and reduce uncertainty concerning decisions. The current paper describes the development of a grid based land-use simulation

Historical maps are a vital and often used source in a variety of disciplines and applications. Since a decade or two, they have moved into the GIS-community. A large scanning project by Lantmäteriverket will make most of the maps in Sweden available as raster images. Two major projects have modelled the maps for storage in

We present a visibility and dominance analysis used for a visual impact assessment of a planned high building located in a central area in Trondheim, Norway. Our visibility analysis results in cumulative viewsheds depicting from which areas one can see one or more of the viewpoints representing the planned high building and from where you

What are the optimum number of contour levels in a sea floor map with coloured depth intervals? This question is answered in terms of information theory. Information theory computes the channel capacity of an information source as the di.erence between the map entropy and the degree of misinterpretations (equivocation). In order to get the parameters

Methods for interactive map animations are still in an early stage compared to more traditional cartography, and the potentials for improvements are significant. This paper focuses on better design for map animations, particularly for the portrayal of the information regarding the temporal dimension. A series of animations are presented and discussed and subsequently introduced to

The NVRG/Sarepta is an implementation of a terrain model server based on a global variable resolution grid. Access to the system is through a web service, which makes it essentially platform independent. The grid tiles are quadrilaterals of nearly homogeneous size across the globe. Finer resolution levels are generated by regular subdivision. The terrain data
