Zoology Photo Scale Perspective Token Tool

Record explicit zoology photo scale and perspective metadata without estimating specimen dimensions.

Description

Attach a scale reference and perspective note to a specimen photograph.

Zoological records separate specimen identity, preparation, anatomical side, behavioral codes and the sources assigning those labels. A specimen name or status is a claim with provenance, while an observation share depends on a stated denominator. Preserving these conventions helps compare records without treating a transcription or visibility count as taxonomic identification or an animal-health assessment.

Attach a scale reference and perspective note to a specimen photograph.

When to use this tool

Use Zoology Photo Scale Perspective Token when you already have photoId, scaleReference, perspectiveNote and need to attach a scale reference and perspective note to a specimen photograph.

How to use the tool and how it works

  1. Enter photoId, scaleReference, perspectiveNote. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read token. Use the output convention below.

Require three nonempty labels; encode [photoId,scaleReference,perspectiveNote] as JSON text.1

  "output": {

}

Limitations and assumptions

  • No photograph is inspected, calibrated or corrected for perspective.
  • 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.

Alternative or Complementary methods

For identity or type status, inspect the original specimen record and cited nomenclatural authority. For behavior or visibility, review the actual observation series and its codebook; this helper preserves one stated label or counting convention.
