Abstract

A computer system for locating real estate service providers by navigating an aerial image map of a geographic region. The system determines a search region corresponding to the geographic region by use of geospatial information associated with the geographic region. Once the search region is determined, the system searches a database for real estate service providers that are associated with the search region and that satisfy certain predetermined criteria.

Claims

1. A method, embodied in a computer system, of presenting real estate service provider information to a user, the method comprising:

displaying, in a viewing window of a web page on a client computer display, a satellite image of a geographic region;

receiving a search request from a client computer application, the search request having geospatial information defining the geographic region;

identifying real estate service providers that have provided real estate services within the geographic region;

transmitting information associated with the identified real estate service providers to the client computer; and

presenting the real estate service providers, on the web page displayed on the client computer, according to at least one of;

amount of real estate service activity in the geographic area, and time since most recent activity in the geographic area.

2. The method of claim 1, wherein the geospatial information comprises elevation information associated with the viewing window.

3. The method of claim 1 wherein the geospatial information comprises latitude and longitude associated with the displayed satellite image.

4. The method of claim 3, wherein the latitude and longitude are associated with the center point of the displayed satellite image.

5. The method of claim 1 in which identifying real estate service providers comprises searching a real estate database having historical real estate service provider information.

6. The method of claim 1 in which the real estate service provider is a real estate agent.

7. The method of claim 1 in which the real estate service providers are further ranked according to client feedback about the service provider.

8. A method, implemented in a computer system, of searching for real estate service providers, the method comprising:

navigating, in a web browser, an aerial image map of a geographic region in a viewing window of a web page;

determining geospatial information corresponding to the geographic region displayed in the viewing window;

determining, at least in part based on the determined geospatial information, a search region corresponding to the geographic region;

searching a real estate database for real estate service providers associated with the search region; and

communicating the search results to at least one selected from the group of;

the web page, a predetermined email address, a predetermined fax machine, and a predetermined mobile device.

9. The method of claim 8 in which the search results comprise a real estate service provider name and associated contact information.

10. The method of claim 9 wherein the associated contact information comprises at least one of an email address, a phone number, a mailing address, a web site, and an instant messenger address.

11. The method of claim 8 further comprising displaying on the web page an advertisement associated with the search results.

12. The method of claim 11 wherein the advertisement is for a real estate service provider in the search results.

13. The method of claim 8 further comprising presenting the search results on the web page displayed on the client computer, wherein the service providers are ordered according to at least one of real estate service activity in the geographic area and most recent activity in the geographic area.

14. The method of claim 8 wherein the geospatial information comprises longitude and latitude information corresponding to the geographic region.

15. The method of claim 8 wherein the geospatial information comprises elevation information corresponding to the height of the viewing window above the aerial image map.

16. In computer readable medium, a real estate application data structure supporting identification of real estate service providers according to predetermined criteria in a networked computer system, comprising:

a data table having a property data field comprising a real estate property identifier that identifies a real estate property; and

a geospatial data field comprising geospatial data associated with the real estate property.

17. The medium of claim 16 in which the real estate application data structure further comprises a time field including time data associated with a sale of the real estate property.

18. The medium of claim 16, further comprising a linked list having a header comprising a real estate service provider identifier and at least one pointer to a property data field in the data table.

19. The medium of claim 16, wherein the geospatial data comprises a latitude and a longitude.

20. A computer readable medium containing a program adapted to implement the method comprising:

navigating, in a web browser, an aerial image map of a geographic region in a viewing window of a web page;

determining geospatial information corresponding to the geographic region displayed in the viewing window;

determining, at least in part based on the determined geospatial information, a search region corresponding to the geographic region;

searching a real estate database for real estate service providers associated with the search region; and

communicating the search results to at least one selected from the group of;

the web page, a predetermined email address, a predetermined fax machine, and a predetermined mobile device.
