Description
Return eligibleZoneArea=zoneArea-excludedZoneArea and weight=eligibleZoneArea/fieldArea.
Precision-agriculture measurements combine spatial cells, sensor clocks, travel speeds, band signals, and application records. A correction or weighted share is meaningful only when coordinate frames, units, timestamps, and coverage bases agree. Supplied calibration and support flags remain distinct from measurements that establish them.
Return eligibleZoneArea=zoneArea-excludedZoneArea and weight=eligibleZoneArea/fieldArea.
When to use this tool
Use Management Zone Area Weight when you have the stated field, sensor, map, or application records and need this correction or geometric/accounting component.
How to use the tool and how it works
- Enter zoneArea, fieldArea, excludedZoneArea. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read eligibleZoneArea, weight. Use the output convention below.
Require positive fieldArea and 0<=excludedZoneArea<=zoneArea<=fieldArea. Return eligibleZoneArea=zoneArea-excludedZoneArea and weight=eligibleZoneArea/fieldArea.1

| fieldArea | Field Area | Required. Finite number; strictly above 0. |
| excludedZoneArea | Excluded Zone Area | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| eligibleZoneArea | Eligible Zone Area | Required. Finite number. |
| weight | Supplied nonnegative component weight under the stated model. | Required. Finite number. |

}Limitations and assumptions
- All areas need the same unit. The denominator remains the whole field, and overlapping management zones or the geometry of exclusions are not checked.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Signed zero is exported as zero.
Alternative or Complementary methods
Verify the measurement calibration, coordinate frame, spatial support, and clock convention before combining this term into a map or control workflow. Use a complete equipment or field model when geometric and operating constraints matter.
