Turf management

A method of watering a turf site, the method comprising:

• measuring at least one parameter by driving a mobile data collection device across the turf site, the mobile data collection device including a sensor spaced away from turf in the turf site for measuring the at least one parameter;
• defining at least one surface area boundary for an irrigation management unit by:
• identifying sprinkler head locations;
• locating a midpoint between at least two sprinkler head locations;
• and
• drawing a portion of the at least one surface area boundary through the midpoint;
• controlling a first plurality of fixed sprinkler heads within a first irrigation management zone according to a first control parameter, the first irrigation management zone including one or more irrigation management units each defined by surface area boundaries where all points within each irrigation management unit are closer to a respective sprinkler head in the first irrigation management zone than to any other sprinkler head in the first irrigation management zone, the irrigation management units of the first irrigation management zone having a first common characteristic;
• controlling a second plurality of fixed sprinkler heads within a second irrigation management zone according to a second control parameter, the second irrigation management zone including one or more irrigation management units each defined by surface area boundaries where all points within each irrigation management unit are closer to a respective sprinkler head in the second irrigation management zone than to any other sprinkler head in the second irrigation management zone, the irrigation management units of the second irrigation management zone having a second common characteristic;
• receiving measurements of the at least one parameter of the irrigation management units;
• and
• adjusting the first and second control parameters based on the measurements of the at least one parameter of the irrigation management units in the first and second irrigation management zones.

A non-transitory computer readable storage device storing data instructions for controlling an irrigation system, the instructions, when executed by a computing device, cause the irrigation system to:

• measure at least one parameter by having a mobile data collection device driven across a turf site, the mobile data collection device including a sensor spaced away from turf in the turf site for measuring the at least one parameter;
• define at least one surface area boundary for an irrigation management unit by:
• identifying sprinkler head locations;
• locating a midpoint between at least two sprinkler head locations;
• and
• drawing a portion of the at least one surface area boundary through the midpoint;
• control a first plurality of fixed sprinkler heads within a first irrigation management zone according to a first control parameter, the first irrigation management zone including one or more irrigation management units each defined by surface area boundaries where all points within each irrigation management unit are closer to a respective sprinkler head in the first irrigation management zone than to any other sprinkler head in the first irrigation management zone, the irrigation management units of the first irrigation management zone having a first common characteristic;
• control a second plurality of fixed sprinkler heads within a second irrigation management zone according to a second control parameter, the second irrigation management zone including one or more irrigation management units each defined by surface area boundaries where all points within each irrigation management unit are closer to a respective sprinkler head in the second irrigation management zone than to any other sprinkler head in the second irrigation management zone, the irrigation management units of the second irrigation management zone having a second common characteristic;
• receive measurements of the at least one parameter of the irrigation management units in the first and second irrigation management zones;
• and
• adjust the first and second control parameters based on the measurements of the at least one parameter of the irrigation management units in the first and second irrigation management zones.
