1. A method for enhancing the display of geospatially-based data on a map, wherein said geospatially-based data is associated with map-based entities, said method comprising:
- (a) specifying a hierarchy for the map-based entities shown on a map;
(b) segmenting the map into logical segments based on the hierarchy of map-based entities;
(c) associating the geospatially-based data with corresponding logical segments;
(d) calculating a corresponding scale factor for each logical segment;
(e) scaling each logical segment according to the corresponding scale factor;
(f) repositioning each logical segment to minimize intersections between each logical segment and any other logical segment; and
(g) displaying a map of the scaled and repositioned logical segments.

Abstract
A method for transforming a map based on associated geospatial data. A map is segmented into logical segments representing map-based entities. The geospatial data is then associated with the logical segments. The logical segments are scaled based upon the associated data. The logical segments are then repositioned to avoid overlapping other logical segments and a new map display based on the scaled and repositioned logical segments is provided.

11. A method for scaling a map based on associated overlay data, the method comprising:
-
(a) intersecting vector representations of a plurality of geographical or political entities with one or more raster images to create a plurality of logical data segments, each logical data segment corresponding to the vector representation of a corresponding geographical or political;
(b) linearly registering overlay data to each logical segment;
(c) calculating a corresponding data density for each logical segment;
(d) scaling each logical segment based on the corresponding data density for the logical segment;
(e) repositioning at least one logical segment in relation to another logical segment;
(f) determining whether any logical segment overlaps any other logical segment; and
(g) providing a map containing the scaled logical segments. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
