Abstract

Method and apparatus for searching a geographic database for properties within a specified range of distances and range of directions from a selected hub location. The invention includes a global computer network, the database, and a search program. The network includes a database computer, a user interface computer, and a search computer. Each database record includes a physical location of the property. The search program takes as inputs a selected hub, a range of distances, and a range of directions. The search program iterates through the records to find those properties the fall within the parameters and displays them to the user.

Claims

1. A method for location of real estate properties by a user, said method comprising the steps of:

(a) providing a property database of real estate properties, said property database including a property record for each of said properties, said property record including a physical location of said property;

(b) providing a hub database of hubs, said hub database including a hub record for each of said hubs, said hub record including a physical location of said hub;

(c) selecting a hub;

(d) selecting a range of distances from said hub;

(e) selecting a range of directions from said hub, said range of directions being independent of said range of distances;

(f) checking each of said property records to determine if said property is within said selected range of distances and said selected range of directions from said hub;

(g) creating a result that includes all of said properties that fall within said selected range of distances and said selected range of directions from said hub;

(h) presenting said result to said user.

2. The method of claim 1 wherein said range of distances is specified by a single distance and a deviation.

3. The method of claim 2 wherein said deviation is predetermined.

4. The method of claim 1 wherein said range of distances is specified by a minimum distance and a maximum distance.

5. The method of claim 1 wherein said range of directions is specified by a single direction and a deviation.

6. The method of claim 5 wherein said deviation is predetermined.

7. The method of claim 5 wherein said single direction is identified by a compass point.

8. The method of claim 1 wherein said range of directions is specified by a first direction and a second direction.

9. The method of claim 1 wherein said property record includes additional special information and wherein said method includes the additional steps of selecting a range of special information, checking each of said property records to determine if said property special information is within said selected range of special information, and restricting said result to only those of said properties that fall within said selected range of special information.

10. A system for location of real estate properties by a user, said system comprising:

(a) a global computer network including a database computer, a user interface computer, and a search computer;

(b) a property database of real estate properties, said property database residing on said database computer, said property database including a property record for each of said properties, said property record including a physical location of said property;

(c) a hub database of hubs, said hub database residing on said database computer, said hub database including a hub record for each of said hubs, said hub record including a physical location of said hub;

(d) an input interface displayed on said user interface computer, said input interface providing the ability for said user to enter search parameters and to initiate a search, said search parameters including a hub selection, a range of distances selection, and a range of directions selection, said range of distances selection being independent of said range of directions selection;

(e) a search program that runs on said search computer, said search program using said search parameters, said hub database, and said property database to create a result that includes all of said properties that are within said range of distances and said range of directions from said hub; and

(f) a result interface that displays said result to said user.

11. The system of claim 10 wherein said range of distances is specified by a single distance and a deviation.

12. The system of claim 11 wherein said deviation is predetermined.

13. The system of claim 10 wherein said range of distances is specified by a minimum distance and a maximum distance.

14. The system of claim 10 wherein said range of directions is specified by a single direction and a deviation.

15. The system of claim 14 wherein said deviation is predetermined.

16. The system of claim 14 wherein said single direction is identified by a compass point.

17. The system of claim 10 wherein said range of directions is specified by a first direction and a second direction.

18. The system of claim 10 wherein said property record includes special information, said search information includes a range of special information selection, and said search program restricts said result to include only properties that are within said range of special information.
