1. A method comprising the steps of:
- operating a plurality of devices on a plurality of lawns according to a first schedule, each device having at least one sensor wherein the plurality of devices comprises two or more different types of devices;
generating, for each device, a respective map including;
setting a positioning point for the device;
acquiring a data set from the at least one sensor in relation to the device'"'"'s orientation, motion and position relative to the positioning point, the data set comprising (i) pitch and roll data of the device, and (ii) data selected from a group consisting of GPS location, speed, velocity, acceleration, power usage, fuel usage, and combinations thereof;
transmitting the data set to a processor; and
processing the data set through the processor to generate the map;
determining, based on the generated maps, an operational efficiency of the plurality of devices operating according to the first schedule;
determining a second schedule for the plurality of devices based on the operational efficiency; and
operating the plurality of devices on the plurality of lawns according to the second schedule.

Abstract
A method is provided for generating a three-dimensional geographical map of a lawn using a mower equipped with sensors for monitoring geographic location, pitch and roll, comprising the steps of: periodically acquiring position, pitch and roll data as the lawn is mowed; transmitting the geographic location, pitch and roll data to a computer processor; and processing the geographic location, pitch and roll data to generate the map. The method is useful for enhancing mowing efficiency and managing the activities of a fleet of mower units.
