Description
Measure observed seed spacing relative to 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.
Measure observed seed spacing relative to a supplied target.
When to use this tool
Use Seed Spacing Observed Target Gap when you already have targetSpacing, observedSpacing and need to measure observed seed spacing relative to a supplied target.
How to use the tool and how it works
- Enter targetSpacing, observedSpacing. 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 observedSpacing-targetSpacing on the same length basis.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| targetSpacing | Target Spacing | Required. Finite number. |
| observedSpacing | Observed Spacing | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedGap | Signed Gap | Required. Finite number. |

}Limitations and assumptions
- No seed positions, spacing variability, suitable seeding rate or planting prescription is inferred.
- 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.
