Abstract

Over the last 15 years there has been a rapid increase in the development and usage of digital maps. Methods for assessing the quality of systems for communicating digital geographical information are frequently described in the literature, but few methods have been empirically evaluated. The quality of cartographic products is especially important for resources management and environmental planning, although it may be important in all application areas where spatial information is used. When designing digital communicative systems, it is crucially important to base system development on empirical interactions with potential users.

In this thesis, empirical methods were used to develop a geographic information system (GIS) for environmental research and monitoring in the Arctic – the Abisko GIS. Approximately 30 potential users were interviewed via a questionnaire while testing a number of alternative interfaces to Abisko GIS. This allowed the qualities of alternative cartographic solutions to be evaluated and the optimal combination of cartographic objects to be implemented in Abisko GIS.

Through statistical inference of the questionnaires, it was concluded that Map Design had the greatest effect on subjects during their evaluation. Gender and the Time spent with evaluation had no significant effect, although Time appeared to play some role for experts and those with experience of GIS. On average, the response to questions asked regarding particular aspects of maps varied diminutively across subjects. Other observations are discussed in the text.
