ISO/IEC 12087-5:2025

ISO/IEC 12087-5:2025 - Overview

ISO/IEC 12087-5:2025 specifies the Basic Image Interchange Format (BIIF) as part of the IPI (Image Processing and Interchange) functional specification. BIIF is a standardized, extensible container format designed to improve interoperability for exchanging imagery and imagery-related data among diverse applications - from commercial imaging to government/defence imagery and Programmer’s Imaging Kernel System (PIKS) data. The standard describes the overall structure, valid fields, and mechanisms to include image, symbol, text and related support data, plus a profiling framework to tailor implementations.

Key topics and technical requirements

• Format structure and fields: Detailed definitions for headers, image segments, symbol segments, text information segments and data extensions to ensure consistent parsing and interpretation.
• Data recording and encoding: Specification of data recording formats and encoding approaches (references existing encodings where applicable).
• Pixel and coordinate models: Logical structure for pixel storage, common coordinate system, display and attachment levels to coordinate multi-element imagery.
• Transportable File Structure (TFS): Mechanism to encapsulate and interchange PIKS image and image-related objects.
• Profiling and conformance: BIIF profiles, profile tables (Annex C Model Profile) and a registration process to define interoperable subsets and extensions; complexity level pro forma and implementation support requirements.
• Annexes: Normative annexes include TFS (A), Vector Quantization (B) and Profiling (C); informative annexes cover implementation considerations, product configurations and example BIIF profiles.

Practical applications

• Exchange of satellite, aerial, or commercial imagery between heterogeneous systems.
• Packaging images with associated symbols, annotations and metadata for GIS, mapping, intelligence, remote sensing and archival workflows.
• Low-bandwidth or limited-resource systems where minimizing formatting overhead and preprocessing/postprocessing is important.
• Interoperable archival or transmission of PIKS-based imagery using the Transportable File Structure (TFS).

Who should use this standard

• Software developers building image ingest/export, archival and rendering tools.
• System integrators implementing interoperable imaging pipelines for government, defence or commercial services.
• Vendors creating imaging formats or devices that must exchange imagery and associated metadata across platforms.
• Standards architects designing profiles or constrained implementations for bandwidth-limited or domain-specific use cases.
