Description
Return claim union, max(0,parcel-union) and max(0,union-parcel).
Agricultural claim records combine declared areas, exclusions, duplicate units and supporting-evidence flags. Avoiding double counting requires the correct intersection or exclusion overlap. A reconciled area/count or verified-token share is bookkeeping rather than legal validation of a claim.
Return claim union, max(0,parcel-union) and max(0,union-parcel).
When to use this tool
Use Farm Claim Parcel Overlap Area Term when checking the stated claim count, area or evidence-support convention.
How to use the tool and how it works
- Enter claimA, claimB, intersection, parcelArea. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read union, unclaimed, excess. Use the output convention below.
Require nonnegative claim and parcel areas with intersection within both claims. Return claim union, max(0,parcel-union) and max(0,union-parcel).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| claimA | Claim A | Required. Finite number; minimum 0. |
| claimB | Claim B | Required. Finite number; minimum 0. |
| intersection | Intersection | Required. Finite number; minimum 0. |
| parcelArea | Parcel Area | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| union | Union | Required. Finite number. |
| unclaimed | Unclaimed | Required. Finite number. |
| excess | Excess | Required. Finite number. |

}Limitations and assumptions
- Area overlap is supplied; an excess flags arithmetic over-allocation without detecting actual parcel intersections or valid claims.
- 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. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review authoritative source records, parcel geometry and applicable program rules with the responsible professionals for actual claims or payments.
