Abstract

A novel system and method for locating real estate properties for potential purchase including a graphical locator interface which permits definition of a desired area for search by placing of a user-controlled selector on a map displayed on a CRT. Additional search qualifications including price, type of structure and others are also specified. The completed specification is then transmitted to a host system and is used for a search of a database of available properties.

Claims

1. A method for locating available properties for purchase comprising the steps performed by a computer of:

(a) selecting a landmark as a reference point from a list of available landmarks;

(b) displaying a map showing said selected landmark, a first area selection cursor having boundaries and information about distance and direction from the center of said first cursor to said landmark;

(c) accepting commands to cause the location of said cursor to traverse said displayed map in any cardinal direction and to change the size of said first cursor;

(d) zooming said displayed map to coincide with the boundaries of said first cursor thereby displaying a higher level of detail;

(e) accepting an indication of completion of said first cursor traversal and size change and converting the area enclosed by said first cursor to values representative of geographic location and maximum distance from said geographic location.

(f) transmitting said data set to a host processor;

(g) receiving said data set by said host processor;

(h) searching a database of properties by said host processor using said received data set;

(i) identifying properties by said host processor within said database which match data indicative of criteria contained in said received data set; and

(j) transmitting by said host processor, information about said identified properties.

2. The method of claim 1 comprising the steps of:

(k) displaying said zoomed map, a second area selection cursor enclosing an area, and information about the distance and direction from the center of said second cursor to said landmark;

(l) accepting commands to cause the location of said second cursor to traverse said displayed map in any cardinal direction, and to change the radius of said second cursor;

(m) accepting an indication of completion of said cursor traversal and size change and converting the area enclosed by said cursor to values representative of geographic location and maximum distance from said geographic location.

3. A method for specifying the approximate geographic location of a real estate property comprising the steps of:

(a) selecting a landmark as a reference point from a list of available landmarks;

(b) displaying a map showing said selected landmark, a first area selection cursor having boundaries, and information about the distance and direction from the canter of said first cursor to said landmark;

(c) accepting commands to cause the location of said first cursor to traverse said displayed map in any cardinal direction and to change the size of said first cursor;

(d) zooming said displayed map to substantially coincide with the boundaries of said cursor, thereby displaying a higher level of detail;

(e) displaying said zoomed map, a second area selection cursor enclosing an area and information about the location of the center of said second cursor relative to said landmark.

4. The method of claim 3 further including the steps of:

(f) accepting commands to cause the location of said second cursor to traverse said displayed map in any cardinal direction, and to change the radius of said second cursor;

(g) accepting an indication of completion of the second cursor traversal and radius change and converting the area enclosed by said cursor to values representative of geographic location and maximum distance from said geographic location.
