Description
Compare a recorded precision-map cell value with a supplied target.
Precision-agriculture records separate spatial reference versions, quality-code sources, calibration factors and target prescriptions. A cross-track error needs a directed planar line, while pulse counts require a compatible volume-per-pulse factor. Local map differences and overlap widths do not select a treatment, control machinery or establish positioning accuracy.
Compare a recorded precision-map cell value with a supplied target.
When to use this tool
Use Precision Map Cell Target Delta when you already have targetCellValue, recordedCellValue and need to compare a recorded precision-map cell value with a supplied target.
How to use the tool and how it works
- Enter targetCellValue, recordedCellValue. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedGap. Use the output convention below.
Return recordedCellValue-targetCellValue in compatible units and reference basis.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| targetCellValue | Target Cell Value | Required. Finite number. |
| recordedCellValue | Recorded Cell Value | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | Signed Gap | Required. Finite number. |

}Limitations and assumptions
- No map is read, target selected or agricultural prescription generated.
- 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
Use the original georeferenced map, calibrated meter and verified machine geometry for field decisions. A full guidance or application analysis must include coordinate system, path extent and equipment constraints beyond one signed offset or overlap width.
