Full title and description

AS/NZS ISO 19165.2:2020 — Geographic information — Preservation of digital data and metadata — Part 2: Content specifications for Earth observation data and derived digital products. This joint Australian/New Zealand adoption implements ISO 19165-2:2020 and provides content-level guidance to support long‑term preservation of Earth observation (EO) data and derived products, with emphasis on provenance and contextual information for spaceborne, airborne and in situ observation missions.

Abstract

Part 2 of ISO 19165 extends the fundamentals in ISO 19165‑1 by specifying the content items and metadata needed to capture provenance, context and other domain‑specific information for Earth observation data and derived digital products. The standard helps create self‑describing geospatial preservation packages that enable future reconstruction and reuse of archived EO datasets without reliance on external documentation.

Scope

This standard specifies content rules and metadata elements necessary to preserve Earth observation data and derived digital products over the long term. It addresses the provenance and contextual information produced by observation missions (spaceborne, airborne and in situ), and defines the content items that should be included in archival, submission and dissemination information packages to ensure datasets remain interpretable and reusable by designated communities in the future.

Key topics and requirements

• Definition of domain‑specific content items and preservation metadata needed for EO data (provenance, processing history, instrument/platform details, calibration and validation information).
• Requirements for packaging geospatial data into self‑describing archival information packages (AIP/SIP/DIP) suitable for long‑term preservation.
• Linkage with ISO 19165‑1 fundamentals (preservation metadata model) and with common archival models (OAIS concepts such as SIP, AIP, DIP).
• Guidance on documenting derived products and processing chains so that derived datasets can be reproduced or reinterpreted later.
• Use of existing encoding/binding recommendations and implementation schemas for imagery and gridded data where relevant.
• Emphasis on provenance capture, contextual documentation and representation information necessary for future usability.
• Conformance expectations for repositories and data stewards implementing EO preservation workflows.

Typical use and users

Intended users include national and institutional data archives, space agencies, remote sensing data centres, GIS and EO data managers, digital preservation professionals, librarians and research organisations. It is used when preparing EO datasets for long‑term archival, designing preservation workflows, writing data management and curation policies, or implementing repository ingestion and dissemination processes that must preserve provenance and context.

Related standards

Key related documents include ISO 19165‑1:2018 (Preservation fundamentals), ISO 19115 (metadata standards for geographic information), ISO 19115‑2 (metadata extensions for acquisition and processing), ISO/TS 19163‑2 (content components and encoding rules for imagery and gridded data), and OAIS (ISO 14721) archival models. These documents are commonly used together to define metadata, packaging and preservation workflows for geospatial and EO datasets.

FAQ

Q: What is this standard?

A: AS/NZS ISO 19165.2:2020 is the Australian/New Zealand adoption of ISO 19165‑2:2020. It defines content specifications and preservation metadata items to support long‑term preservation of Earth observation data and derived digital products.

Q: What does it cover?

A: It specifies the information that should accompany EO datasets—provenance, processing history, instrument/platform context, calibration/validation details and related representation information—so that archived products remain interpretable and reusable over the long term.

Q: Who typically uses it?

A: Data archives, space agencies, remote sensing centres, GIS and EO data managers, preservation specialists, research institutions and libraries involved in curating, ingesting or disseminating Earth observation datasets.

Q: Is it current or superseded?

A: The ISO original was published on 6 July 2020 and the AS/NZS adoption was published on 27 November 2020. The document remains the current Part 2 of ISO 19165 (1st edition, 2020) and the ISO record was subject to periodic review; users should check their national standards body for any later amendments or revisions.

Q: Is it part of a series?

A: Yes — it is Part 2 of the ISO 19165 series (Part 1: Fundamentals — ISO 19165‑1:2018). It is intended to be used alongside other geographic information standards such as ISO 19115 (metadata), ISO/TS 19163 (imagery content components), and OAIS archival guidance (ISO 14721).

Q: What are the key keywords?

A: Earth observation, preservation, provenance, metadata, archival information package, geospatial data, remote sensing, ISO 19165, long‑term preservation.
