System and method for representing parameters in a work site database
DCFirst Claim
1. An apparatus for directing the operation of a working machine on a work site, comprising:
- a position sensing system adapted to sense the position of at least one fixed point located on the working machine as the working machine traverses the work site and responsively producing a position signal;
a controller, adapted to receive the position signal, the controller containing a database containing data representing a parameter of the work site, the data contained in a data structure, the data structure containing a plurality of data objects associated with the data structure, each data object representing a defined section of the work site and represented by a set of predefined coordinates and at least one layer object, each layer object having a predefined number or cell objects, each cell object having an associated value of the parameter and defined by a set of coordinates derived from said set of predefined coordinates; and
directing means, coupled to the controller, for accessing the database and responsively directing operation of the working machine.

Abstract
The present invention provides a site database structure for storing data for access by an application program being executed on a control system on a work machine. The work machine operates at a work site. The data representing a parameter of the work site. A data structure is stored in the memory. The data structure includes information resident in a database used by the application program. A plurality of data objects are associated with the data structure. Each data object represents a defined section of the work site and is represented by a set of predefined coordinates. At least one layer object is associated with each data object. Each layer object has a predefined number of cell objects. Each cell object has an associated value of the parameter.

5. A method for storing data for access by an application program being executed on a control system on a work machine, the work machine operating at a work site, the data representing a parameter of the work site, including the steps of:
-
dividing the work site into a plurality of defined sections, each defined section having predetermined dimensions; assigning a data object to each defined section, each data object including a set of predefined coordinates, the set of predefined coordinates representing a corresponding defined section; associating each data object with at least one layer object, each layer object having a predefined number of cell objects, each cell object having an associated value of the parameter; and deriving a coordinate of each of said cell objects from its data object'"'"'s set of predefined coordinates.

6. A memory for storing data for access by an application program being executed on a control system on a work machine, the work machine operating at a work site, the data representing a parameter of the work site, comprising:
-
a data structure stored in the memory, the data structure including information resident in a database used by the application program; a plurality of data objects, associated with the data structure, each data object representing a defined section of the work site and represented by a first set of predefined coordinates; and at least one layer object associated with each data object, each layer object having a predefined number of cell objects, each cell object having an associated value of the parameter and represented by a second set of coordinates derived from said first set of predefined coordinates. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
