– The purpose of this paper is to establish common metrics for web-based mapping applications to facilitate user decision making and enhance information providers’ product design.
– The metrics were developed from a combination of literature review and case studies. From the literature review, the authors identified three major areas of assessment for web-based mapping applications. The authors then studied six online applications to refine the metrics.
– The results suggest that web-based mapping applications can be evaluated from three major aspects: data content, geographic information systems (GIS) functionality and usability. The authors have developed detailed measures for each factor through the evaluation of the six applications.
– The metrics developed from this study could be used as a standard for online spatial information users to choose appropriate products according to their needs. It can also provide valuable information for data providers to improve their products.
– To the best of the authors’ knowledge, this is the first study that has systematically examined web-based mapping applications in academic libraries. Results from this study could be a valuable tool for librarians as well as general information users without background of GIS and usability to evaluate online mapping resources.
