Public Web Mapping: preliminary usability evaluation

1. Introduction Public Web Mapping sites are not new phenomena any more. Since the introduction of Xerox PARC Map Viewer in 1993 (Putz, 1994), many applications that utilise the World Wide Web (WWW) have been developed and led to a significant change within the field of GIS. Today, many web mapping sites allow end users to interact with online maps in new and innovative ways. Yet, while the development of internet applications in the last decade and the increase in the number of the web sites has resulted in an increase in the number of web usability studies (Nielsen, 2003), the area of web mapping has received relatively little attention and there is no recorded evaluation of commercial web mapping sites. In this paper, we provide preliminary findings from the evaluation of commercial web mapping.
