Abstract Nowadays, there are many area-based Geographic Information Systems (GIS) applications such as real estate valuation, land tax, farming support and cost–benefit analysis. Areas used in such applications are calculated by means of two-dimensional plane geometry. However, the computed area value is not the exact area value in the terrain. In order to calculate the exact area value of a parcel, area corrections due to various factors must be taken into account. These factors are selection of projection, slope of the terrain, elevation of the terrain and scale of the map. Selection of projection and slope of terrain are available; elevation of the terrain and scale of map are not available in all GIS software. In this study, the effect of area corrections on the area value calculated from the map is examined with sample applications and the results are presented to the GIS users. According to the results, GIS users should select the equal area projection. In addition, scale of map, elevation and slope of terrain should be taken into account in the area calculation where land measurements are not possible.

Landscape Attributes

The role of landscape valuation and extended cost-benefit analysis inlandscape conservation decision-making is first addressed. It is stressed that substantial research on how to value alternative conservation schemes is required, in order to cope with emerging policy needs. An analytical frame for the valuation of alternative landscape conservation schemes is then discussed. This frame enablesthe analyst to sequentially disaggregate values for whole landscape changes over attributes. This is an essential operation if the optimal bundle of landscape attributes is to be selected by cost-benefit analysis. The concept of substitution between landscape attributes plays an essential role within the whole analytical frame. The circumstances that lead to anticipate substitution between landscape attributes are explored. A brief review of the alternative empirical strategies for landscape valuation is then carried out, to check whether they permit sequential desegregation of landscape value over attributes. Next, an empirical application to the valuation of landscape attribute changes in the Pennine Dales Environmentally Sensitive Area is presented. The empirical results confirm the idea of the prevalence of substitution in valuation in most practical contexts. To illustrate the potential of the proposed approach, a sequential cost-benefit analysis of attribute changes along consistent paths of aggregation is then carried out – which eventually leads to the selection of optimal bundles of landscape attributes. Some problems and limitations of the approach are also discussed. Among them, the question of non-uniqueness, or path dependency of the optimum is given particular consideration.

This paper was written to guide educators in the selection of computer systems for instructional applications. Four systems representing different cost categories are compared via a set of twenty-five parameters. Besides the PLATO system, the other three computer systems are different capability microcomputers. The approach of this study was to compare computer systems by enumerating the costs and benefits. Problems associated with the cost-benefit analysis are also discussed.

The ProblemEconomic efficiency is naturally thought to be a virtue of social policies and decisions, and cost-benefit (CB) analysis is commonly regarded as a technique for measuring economic efficiency. It is not surprising, then, that CB analysis is so widely used in social policy analysis. However, there is a great deal of controversy about CB analysis, including controversy about its underlying philosophical rationale. The rationales that have been proposed fall into three basic, though not mutually exclusive categories. There are moralist views to the effect that an acceptable CB analysis would provide, or contribute to, an ethical appraisal of proposed policies or projects. There are rationalist views to the effect that an acceptable CB analysis would contribute to the selection of social policies and projects that are “socially rational.” Finally, there are so-called management science views to the effect that the purpose of CB analysis is to promote the achievement of objectives held by the policy maker, whatever they may be. Different positions are available within each of these categories. But there is also the possibility that CB analysis lacks any viable rationale. I will examine some of the major rationales for CB analysis in this paper, and I will suggest that the last view is close to the truth.
