ABSTRACT:
A technique is provided to display a view perspective of an electronic map containing a number of viewable points of interest about a point of reference. The technique assigns a weighted importance value to each point of interest. Before displaying the view perspective of the requested map, the weighted importance value of each point of interest is summed and compared against a target value. If the summed weight substantially equals the predefined, the corresponding viewable points of interest are displayed in the view perspective.
