A method and apparatus for imprinting high resolution images onto fields, such as sports fields and landscapes is disclosed. In one embodiment, precise and consistent lawn and field patterning is accomplished by use in combination of a global positioning system; a processor for generating a desired pattern which is translated into patterning instructions; and a patterning implement which is used for generating detailed patterns and for imprinting said patterns on any of natural or artificial lawns and fields, covered areas, and landscapes. The patterning implement comprises a plurality of independent printing mechanisms incorporated within said patterning implement, each of the independent printing mechanisms coupled to receive patterning instructions from the processor and operate selectively in response thereto. The invention also comprises means for guiding the patterning implement to position it along a desired path at least in part with information from said global positioning system; and means for individually controlling each of said independent printing mechanisms incorporated within said patterning implement responsive to said patterning instructions and in coordination with positioning of said patterning implement along said desired path.

1. An apparatus for precise and consistent lawn and field patterning, comprising: a global positioning system;a processor for generating a desired pattern, wherein said pattern is translated into patterning instructions;a patterning implement for imprinting said pattern into turf comprising: a plurality of independent printing mechanisms incorporated within said patterning implement, each of said independent printing mechanisms comprises: a load bearing roller which, when rolled over turf, imparts stress on blades of the turf such that said blades lay down in a direction of rolling when rolled over by said load bearing roller;a pneumatic system comprising: an air source;a turf stuffer comprising a plurality of discrete air knife sections;a plurality of actuators for controlling the pressure of air delivered to each of the air knife sections; anda plurality of air flow valves for controlling an angle of air delivery in each of the air knife sections;wherein each of said independent printing mechanism is coupled to receive said patterning instructions from said processor and operate selectively in response thereto;means for guiding said patterning implement to position it along a desired path at least in part with information from said global positioning system; andmeans for individually controlling each of said independent printing mechanisms incorporated within said patterning implement responsive to said patterning instructions and in coordination with positioning of said patterning implement along said desired path. 2. The apparatus of claim 1, said patterning implement comprising any of: means for controlling the length of individual blades of the turf to expose color stratifications;means for applying color altering media to the turf;means for generating variations in pattern contrast to produce smooth gradients along a length of a patterned feature; andwherein said patterning implement further comprises:means for increasing resolution of the pattern by varying contrast intensity across a width of an imprinted swath. 3. The apparatus of claim 1, said processor further comprising any of: means for rendering said pattern to avoid loss of image quality through angular view distortion by skewing the pattern to enhance the pattern for optimal viewing from a defined viewing angle;means for sequential control of said independent printing mechanisms incorporated within said patterning implement to provide a paced unveiling of the pattern; andmeans control of said independent printing mechanisms incorporated within said patterning implement to provide multiple pattern layers, wherein pattern components divided up and imprinted sequentially. 4. The apparatus of claim 3, said means for rendering further comprising: means for applying aspect ratio and keystone correction to said pattern for a defined camera angle. 5. The apparatus of claim 1, said independent printing mechanisms incorporated within said patterning implement, further comprising: means for perturbing turf to change its visual appearance.
