Description
Check a supplied detection distance in a half-open survey bin.
Conservation observations depend on sampling effort, specimen provenance, spatial precision and the population being assessed. Survivors among assessed plants differ from survivors among all planted plants. Coordinate rounding or cell assignment changes a display location without guaranteeing protection, and a time-gap threshold does not establish independent observations.
Check a supplied detection distance in a half-open survey bin.
When to use this tool
Use Breeding Survey Detection Distance Bin when you already have distance, lowerInclusive, upperExclusive and need to check a supplied detection distance in a half-open survey bin.
How to use the tool and how it works
- Enter distance, lowerInclusive, upperExclusive. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read inBin. Inspect inBin before interpreting the associated values.
Require distance/lower>=0 and upper>lower; return lower<=distance<upper.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| distance | Distance | Required. Finite number; minimum 0. |
| lowerInclusive | Lower Inclusive | Required. Finite number; minimum 0. |
| upperExclusive | Upper Exclusive | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| inBin | In Bin | Required. Boolean. |

}Limitations and assumptions
- No distance, detection function, survey design, abundance or species identity is estimated.
- 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 original field records, specimens, survey design and location-access requirements. Use the complete ecological and spatial method for population or protection decisions; local rates, interval flags and source-qualified labels do not supply it.
