Abstract

A method and system for applying substance formulations to a land area is disclosed. A flexible, easily modifiable graphical representation of subareas of the area is provided, wherein to each subarea it is desired to apply a combination of one or more substance formulations uniformly throughout the subarea. A user (e.g., a farmer) needs only to specify a boundary for each subarea on a graphical image of the land area for computationally defining the subarea. Subsequently, since the land area image and the subarea boundaries thereon are geographically referenced to latitude and longitude coordinates, when applying such formulations to the land area, the present invention utilizes global positioning system (GPS) signals to thereby determine when such a subarea boundary has been traversed so that a corresponding change in the applied formulation(s) can be performed.
