EANJ_LZH_59: Low-Resolution Visual Record of a Jade Object (Public Preview)

1. Dataset Context

This dataset forms part of a systematic digital visual archiving project.It documents multi-angle, low-resolution image data of a single jade object (EANJ_LZH_59) and is released as the public preview layer within a tiered data structure.

2. Research Purpose

This dataset was generated through standardized image acquisition and organization to provide independently verifiable baseline visual data, supporting researchers in conducting the following activities within their own methodological frameworks:

Morphological comparative studies

Teaching and illustrative use

Image-based, non-invasive analysis

The low-resolution images are intended solely for public preview purposes.The original high-resolution image data (approximately 42 megapixels per image) are published as a separate dataset (Record B) under restricted access.

Access requests should be submitted via the following DOI:https://doi.org/10.5281/zenodo.20029229

3. Data Description

3.1 Object Information

Approximate reference values (non-precision measurements):

Length: 6.4 cm

Width: 1.7 cm

Thickness: 1.7 cm

Weight: 39 g

Note: The above measurements are reference values derived from image-based observation and do not constitute precise metrological results.

3.2 Image Content

The low-resolution public preview includes four representative images selected for structural identification and basic visual reference:

Overall views

EANJ_LZH_59_OVERALL_A

EANJ_LZH_59_OVERALL_B

Macro views

EANJ_LZH_59_MACRO_B

EANJ_LZH_59_MACRO_E

This public preview represents a subset of representative images.The complete multi-angle high-resolution dataset (Record B) contains a broader range of viewing angles and more detailed visual documentation.

3.3 Imaging Method

Equipment: Full-frame digital camera with a 90 mm macro lens

Format: Captured in RAW format; converted to JPEG for release

Lighting: Controlled lighting environment

Background: Neutral background

Physical intervention: None performed

Post-processing: Limited to global exposure and white balance adjustment

4. Data Access & Structure

This dataset follows a tiered publication structure:

Record A: Low-resolution public preview (this record)

Record B: High-resolution original images (restricted access)

This structure distinguishes the public presentation layer from the research-grade data access layer.

5. Usage & Licensing

This dataset is intended for:

Academic research

Teaching purposes

Non-interpretive visual and comparative analysis

Any uses beyond the above—including commercial applications, redistribution, or dissemination in non-academic contexts—require prior authorization.

6. Notes on Interpretation

This dataset provides only visual information directly observable in the images and contains no interpretive, attributive, or historical assessments.

7. Access Information

The complete high-resolution image dataset (Record B) has been published as an independent dataset under restricted access.Access requests should be submitted via the following Zenodo DOI:https://doi.org/10.5281/zenodo.20029229
