ISO/IEC 18042-4:2006/Amd 1:2011

Overview

ISO/IEC 18042-4:2006/Amd 1:2011 is an official amendment to the international standard focusing on computer graphics and image processing, specifically addressing the Spatial Reference Model (SRM) language bindings for the C programming language. Published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), this amendment refines and updates Part 4 of the SRM standard to ensure more robust and efficient integration with C-based software systems.

The Spatial Reference Model is crucial for accurately defining spatial data and operations within computing environments, enabling applications to achieve consistent spatial referencing, transformations, and interoperability.

Key Topics

• SRM Language Bindings for C: Provides the updated technical specifications and interfaces for implementing SRM within C programs, which is critical for developers working in computer graphics, geospatial computing, and image processing domains.
• Amendment Updates: Includes enhancements, bug fixes, and clarifications improving how SRM interacts at the language level, ensuring better performance and usability.
• Standard Compliance: Outlines the requirements and best practices for conforming to the SRM guidelines when working in C, promoting consistency across various software implementations and systems.
• Integration Guidance: Addresses installation and usage instructions for the SRM amendment package, emphasizing proper file management and environment setup to maintain functionality, especially for compound HTML documents.

Applications

This ISO/IEC standard amendment is pivotal for industries and sectors relying on spatial computing and precise graphical rendering, such as:

• Geographic Information Systems (GIS): Enhances spatial data processing and coordinate transformations within GIS software written in C, contributing to accurate map rendering and spatial analysis.
• Computer Graphics Development: Facilitates better handling of spatial references in graphical applications, scientific visualization, and simulation tools.
• Image Processing Systems: Supports spatial modeling for complex image data manipulation and transformation in medical imaging, remote sensing, and multimedia applications.
• Software Engineering for Spatial Data: Assists developers in creating interoperable and standard-compliant spatial computing modules that integrate seamlessly with existing C codebases.

Related Standards

• ISO/IEC 18042-1:2006 - Defines the general Spatial Reference Model framework, providing foundational concepts that complement Part 4.
• Other Language Bindings in the ISO/IEC 18042 Series - Includes language bindings for C++, Java, and other programming languages, facilitating SRM’s multi-language support.
• ISO 19111 - Geographic information - Spatial referencing by coordinates, often used in conjunction with SRM standards for comprehensive spatial referencing solutions.
