This paper continues a project which has developed a major reconceptualization and revision of how borders may be seen and measured through the use of GIS by allowing us to talk about the specific qualities of borders in terms of opportunity and willingness: ease of interaction and salience, respectively. This reconceptualization has also lead to the creation of a dataset which lets us go beyon...

Stream power is a widely used parameter to investigate, engineer, and manage river systems. The varied uses of stream power are increasing as it becomes easier to derive stream power using remotely sensed data coupled with Geographic Information Systems (GIS) and improved computational power and technology. This document was created to provide clarity to researchers and practitioners using stre...

Time to Vote? Despite the centrality of voting costs to the paradox of voting, little effort has been made to accurately measure these costs outside of a few spatially limited case studies. In this paper, we apply Geographic Information Systems (GIS) tools to validated national election survey data from New Zealand. We calculate distance and travel time by road from the place of residence to th...

The life satisfaction approach has recently emerged as a new technique in the suite of options available to non-market valuation practitioners. Employing data from the Household, Income and Labour Dynamics in Australia (HILDA) survey and Geographic Information Systems (GIS), this paper examines the influence of scenic amenity on the life satisfaction of residents of South East Queensland (SEQ),...

Geodemographic systems can make important contributions toward more effective marketing and branch location research within financial service organizations. This article reviews the potential of geodemographics to support various activities undertaken by financial institutions and discusses the role that Geographic Information Systems (GIS) can play in enhancing geodemographic products. Reviewi...

This study aims to develop an economic evaluation method for installing photovoltaic power generation in ordinary homes using GIS (Geographic Information Systems). The conclusions can be summarized in the following three points: 1) This method determines the profit and loss and payback period in order to evaluate the installation of photovoltaic power generation, taking into account the price o...

1. INTRODUCTION Geographic Information Systems (GIS) provide well-developed tools for query, analysis and display of point, line, and polygon data, and there are well-developed communities that use these data types and rely heavily on GIS tools. Many meteorological datasets consist of combinations of time series and grids. Tools for query, analysis and display of these data types are less well ...

In this paper we describe the application of analogical structure matching techniques to the domain of Geographic Information Systems (GIS). Automatic categorisation of map data into roads, buildings etc. is currently based on isolated objects. We describe how identifying analogous clusters of objects can categorise ambiguous polygons by introducing context into the categorisation process. We d...
