Towards Extending Web Map Services

In English This paper begins with describing a case study of using the standard Web Map Services (WMS; from Open Geospatial Consortium) for mobile applications. There are two experiences from this case study that are interesting for the generalisation community: the amount of map information on the screen and the map file size. In this paper a usability study of the amount of map information is presented. The result from this study indicates that we should not only consider scale when determining which generalisation algorithms and/or parameters to use, but that we also should consider the amount of information. The paper also contains a short discussion about methods to restrict map file sizes in WMS.
