Description
Return leaf-outline solidity and convex-area deficit.
Botanical measurements use explicit specimen geometry, pixel scales, length origins and angular direction. A projected-area ratio or geometric contribution summarizes supplied measurements without identifying a species, recovering an actual shape or establishing biological health.
Return leaf-outline solidity and convex-area deficit.
When to use this tool
Use Leaf Outline Solidity when checking the stated plant-measurement, geometry or angular convention.
How to use the tool and how it works
- Enter leafArea, hullArea. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read solidity, deficit. Use the output convention below.
Return leaf-outline solidity and convex-area deficit. Require hullArea > 0 and leafArea in [0,hull]; solidity = leaf/hull, deficit = hull-leaf.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| leafArea | Leaf Area | Required. Finite number; minimum 0. |
| hullArea | Hull Area | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| solidity | Solidity | Required. Finite number. |
| deficit | Deficit | Required. Finite number. |

}Limitations and assumptions
- Areas and hull are supplied, not segmented or geometrically validated; no species or plant-health inference is made.
- 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
Inspect the specimen and measurement protocol, apply verified calibration and use an appropriate biological or geometric model for substantive interpretation.
