Methods and apparatus for providing a topology view based on heuristic information density
First Claim
1. A computer-readable medium whose contents cause a computer system to display a map having points of interest at a view perspective, the computer system having a map viewer with instructions to perform the steps of:
- retrieving a set of one or more viewable points of interest, each point of interest having an assigned weight;
summing the weights of one or more viewable points of interest;
determining whether the summed weights of one or more viewable points of interest substantially equals a target weight; and
displaying the set of one or more viewable points of interest if the summed weights of one or more viewable points of interest substantially equal the target weight.

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.

9. A computer system for displaying a map having points of interest at a view perspective, the computer system comprising:
-
a memory containing;
a map viewer computer program having a first method of invocation to retrieve the total weight of viewable points of interest, the map viewer computer program retrieving one or more viewable points of interest, each viewable point of interest having an assigned weight;
a zoom to density computer program for invoking the first method to determine whether the total weight of viewable points of interest substantially equals a target weight, the map viewer displaying the viewable points of interest if the total weight of viewable points of interest substantially equals a target weight; and
a processor for running the map viewer computer program and the zoom to density computer program. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
