Overview
ISO 19115-1:2014/Amd 1:2018 is an important amendment to the ISO 19115-1:2014 international standard, titled Geographic Information - Metadata - Part 1: Fundamentals. Published by the International Organization for Standardization (ISO), this amendment provides crucial updates and refinements to the metadata principles that guide the description and management of geographic information. As part of the ISO Technical Committee ISO/TC 211 on Geographic Information/Geomatics, this document ensures metadata standards reflect recent technological advancements and interoperability needs.
This amendment specifically updates various references, definitions, and metadata class structures to enhance clarity, precision, and compatibility with related standards. By adopting ISO 19115-1:2014/Amd 1:2018, organizations can improve the quality, accessibility, and exchange of geographic metadata to support diverse applications.
Key Topics
- Metadata Fundamentals: Enhances the core principles governing the documentation of geographic information, including scope, data representation, and citation details.
- Updated Referencing Standards: Modernizes normative references such as ISO 4217:2015 for currency codes and updated versions of ISO 19103, ISO 19109, ISO 19110, and ISO 19119 standards.
- Spatial Representation Classes: Introduces detailed classes for spatial data representation, including grid and vector spatial objects, georectified and georeferenceable representations, and topology levels for spatial relationships.
- Range Dimension Information: Defines comprehensive metadata for the description of attribute value ranges, covering sample dimensions, max/min values, units, scale factors, and statistical measures such as mean and standard deviation.
- Actors and Citation Information: Specifies updated classes and attributes for actors (individuals or organizations) responsible for geographic datasets, enhancing traceability and accountability.
Applications
ISO 19115-1:2014/Amd 1:2018 is essential for professionals and organizations involved in geographic information systems (GIS), spatial data infrastructure (SDI), environmental studies, urban planning, and geospatial research. Specific applications include:
- Geospatial Data Cataloguing: Creating standardized metadata to describe datasets for effective discovery, retrieval, and use.
- Data Quality Management: Ensuring accurate documentation of spatial data properties, measurement units, and transformation parameters to support data integrity.
- Interoperability: Facilitating data exchange across different GIS platforms and international borders by adhering to updated international standards.
- Spatial Analysis and Mapping: Enabling precise geolocation, representation, and analysis through enhanced metadata descriptions of spatial features and coverage.
- Regulatory Compliance: Meeting national and international requirements for metadata standards in government, research, and commercial sectors.
Related Standards
For comprehensive geographic metadata management, ISO 19115-1:2014/Amd 1:2018 aligns with several complementary standards:
Adoption of these standards together fosters cohesive and interoperable geographic metadata frameworks necessary for modern geoinformation systems and data governance.
