Abstract
In the past, point data only play a minor role in map generalization, as points are either already the result of generalization or are used for objects which are only shown on large scale maps. Now, with the growing availability of web mapping services the role of point data has changed: Besides route planning, the most common function of web maps is the visualization of user queries for points of interest. The limited size of commonly used displays often results in a smaller scale as would be appropriate for the maps content. The state of the art to resolve occurring cluttered point sets, is on the one hand interactivity and on the other hand the selection of points. Thus, often the available space is not optimally used. Therefore, we propose a displacement method to improve the readability of dense sets of points of interest.
