Handbook on Indicators for Integrated Coastal and Ocean Management

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).

LUCIA – A tool for land use change impact analysis

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

Example applications of historical maps in GIS and databases

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

Visibility and dominance analysis: Assessing a high building project in Trondheim

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

Investigation of the channel capacity of seafloor maps with coloured depth intervals

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

Human interaction with animated maps: The portrayal of the passage of time

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

A concept for creating, storing, updating and delivering variable resolution terrain models

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

GIS (Geographical Information Systems) as a Basis for Sustainable

South Africa adheres to global Sustainable Development initiatives, and acknowledges through its 2006 draft publication A Strategic Framework for Sustainable Development in South Africa (NFSD) that the Government through various Acts has a legally binding obligation to take responsibility for the environment, the economy and society. In applying these principles as an emerging nation, South

Model inventory

A number of 20 modelling tools are described in so-called ‘standardised model descriptions. The models described in this manner have been selected based both on the primary model foci and lack of coverage in former model reviews at the EEA. These templates are based on information available in reports or other publicly available documentation. (Download

Your vision or my model? Lessons from developing participatory land use scenarios at the European

This paper describes and analyses the participatory process in the scenario development in PRELUDE. It was presented at the international workshop “Formalised and Non-Formalised Methods in Resource Management. Knowledge and learning in participatory processes”, 21/22 September 2006, Osnabrueck, Germany (Download Report 2006) (6 pages, 49KB PDF)
