Abstract

A system and method is provided of generating a map. In one aspect, the map is selected based on a location provided by a user and listings are selected based on their proximity to the location, whether they match a query provided by the user, and the number of matching listings within regions of the map.

Claims

1. A method of providing a map covering an area comprising:

receiving a query via one or more processors, wherein the query includes a search term and a search area;

determining matching listings with the one or more processors, wherein a matching listing comprises a listing associated with a geographic location within the search area having information corresponding to the search term;

dividing, with the one or more processors, the search area into a plurality of regions and selecting, with the one or more processors, a number of matching listings for each region, wherein for each region the selected number of matching listings is proportional to the density of matching listings in that region; and

providing, with the one or more processors, a map of the search area and information about the selected number of matching listings for each region in the search area.

2. The method of claim 1 wherein a listing has information corresponding to the search term when the listing has information that includes the search term.

3. The method of claim 1 wherein a matching listing comprises a business listing associated with a street address.

4. The method of claim 1 wherein the search area is determined from the coordinates of a map that is displayed to the user.

5. The method of claim 1 wherein the plurality of regions are substantially equal in area.

6. The method of claim 1 wherein the information about the selected number of matching listings for each region comprises a second map showing the location of at least one of the selected number of matching listings.

7. The method of claim 6 further comprising compositing the second map with the map of the search area.

8. The method of claim 1 wherein the information about the selected number of matching listings for each region comprises text data for at least one of the selected number of matching listings.

9. A system of providing a map covering an area comprising:

a memory having instructions stored therein; and

a processor coupled to the memory and configured to execute the instructions stored in the memory in order to;

receive a query, wherein the query includes a search term and a search area;

determine matching listings, wherein a matching listing comprises a listing associated with a geographic location within the search area having information corresponding to the search term;

divide the search area into a plurality of regions and select a number of matching listings for each region, wherein for each region the selected number of matching listings is proportional to the density of matching listings in that region; and

provide a map of the search area and information about the selected number of matching listings for each region in the search area.

10. The system of claim 9 wherein a listing has information corresponding to the search term when the listing has information that includes the search term.

11. The system of claim 9 wherein a matching listing comprises a business listing associated with a street address.

12. The system of claim 9 wherein the search area is determined from the coordinates of a map that is displayed to the user.

13. The system of claim 9 wherein the plurality of regions are substantially equal in area.

14. The system of claim 9 wherein the information about the selected number of matching listings for each region comprises a second map showing the location of at least one of the selected number of matching listings.

15. The system of claim 14, wherein the processor is further configured to execute instructions to composite the second map with the map of the search area.

16. The system of claim 9 wherein the information about the selected number of matching listings for each region comprises text data for at least one of the selected number of matching listings.
