US Patent:

61190691, Sep 12, 2000

Filed:

Mar 1, 1999

Appl. No.:

9/258962

Inventors:

James Darrell McCauley - Clarendon Hills IL

Assignee:

Case Corporation - Racine WI

International Classification:

G06F 1900

US Classification:

702 5

Abstract:

A system and method for determining the boundaries of a field is disclosed. The system and method utilizes computational geometry and, in particular, the alpha shape of the field to derive the field boundary of a set of georeferenced data points. The method includes collecting georeferenced data for the field, assigning the georeferenced data to a data set, filtering the data to remove anomalous data points, filtering the data to remove known inside points, scaling the point coordinates from decimal to integer form, determining the alpha shape of the set, buffering the alpha shape to compensate for antenna position, and outputting the field boundary.

US Classification:

702 5

Abstract:

A method and apparatus for determining management zones in a field for precision farming. The method and apparatus use a self-organizing network, such as a Kohonen neural network, to perform the classification of site-specific farming data into management zones in a farm field. The self-organizing network is configured to learn the proper classifications through a learning or training process.
