1. A system for mapping terrain using at least a first machine and a second machine traveling along the terrain, the system comprising:

  • a controller for each of the respective first and second machines, each respective machine including a plurality of sensors in electrical communication with the controller of each respective machine, the controller configured to;

    receive, from the plurality of sensors located on each respective machine including a steering sensor, a ground speed sensor, and a payload sensor, a plurality of machine parameters indicative of sensed operations of the respective machine as the respective machine travels along the terrain, the plurality of machine parameters including a steering parameter of the respective machine sensed by the steering sensor, a around speed of the respective machine sensed by the ground speed sensor, and a payload weight of the respective machine sensed by the payload sensor;

    determine, based on the received machine parameters for the respective machine, a geometry and a grade of a plurality of paths on the terrain along which the respective machine travels;

    create, based on the determined geometry and grade for the respective machine, a map indicating the plurality of paths for the respective machine;

    determine at least one of an efficiency characteristic and a productivity characteristic for the respective plurality of paths based on the received machine parameters for the respective machine;

    select at least one path from the plurality of paths for the respective machine to travel along in a future operation based on the at least one of the efficiency characteristic and the productivity characteristic for the respective plurality of paths for the respective machine; and

    display the map to an operator of the respective machine, the map including a display of the at least one path selected by the controller;

    wherein the at least one of the efficiency characteristic and the productivity characteristic indicates at least one of a fuel efficiency or an amount of payload moved.
