1. A method for controlled spraying of a surface with fluid from a mobile container, the method comprising:

  • obtaining a plurality of spatial coordinates for the surface;

    establishing boundary coordinates defining one or more exclusion zones on the surface which are not to be sprayed;

    traversing at least a portion of the surface with the container along a path, the container having a spray nozzle for controllably delivering a spray width W of fluid at an areal spray rate R(volume/area) to the surface along the path, andfor each current position of the container along the path;

    obtaining position coordinates;

    determining the areal spray rate R; and

    automatically spraying the spray width W at a sprayed position along the path with the fluid from the container, if the following spray conditions are met, includingthe spray width is outside the exclusion zones, andthe areal spray rate R is less than a predetermined maximum spray rate RMAX.
