System and method for controlling a work machine

A system for moving material at a work site, comprising:

• a work machine comprising a chassis, a material mover carried by said chassis and defining a material mover position, a location sensor carried by said chassis, and a steering mechanism configured to control a travel direction of said work machine;
• and
• a controller system operably coupled to said material mover, said location sensor, and said steering mechanism, said controller system configured to:
• store a sequence of travel paths for said work machine to follow;
• control said steering mechanism to follow said sequence of travel paths;
• determine said material mover position;
• determine followed travel positions of said work machine based on signals from said location sensor;
• generate an as-built map as said work machine follows said sequence of travel paths based on said material mover position and followed travel positions;
• compare said as-built map to a desired terrain map;
• generate a revised sequence of travel paths for said work machine to follow based on said comparison between said as-built map and said desired terrain map, wherein said revised sequence alters a material volume movement sequence of said work machine;
• and
• control said steering mechanism to follow said revised sequence of travel paths.
