• Geospatial data has a long
history using Metadata

– Maps and Charts
– Imagery
– Digital data files

Metadata perspectives
• Why it’s important?
– Expansion in the use of Geographic Information
– Proliferation of data
– Non-geographers using geospatial data
– The producer is not the user
– Geospatial data is imperfect
– A model, a “point of view”
– Assumptions, limitations, approximations,
simplifications
– Expensive
– Reuse
– Data management
• Why should it be standardized?
– Provide an understanding of data – around the
globe and across information communities
Metadata Applications

ISO 19115:2003
Scope
• ...the schema required for describing geographic
information and services.
• ...information about the identification, the extent, the quality,
the spatial and temporal schema, spatial reference, and
distribution of digital geographic data.
• ...applicable to the cataloguing of datasets, clearinghouse
activities, and the full description of datasets for a wide
range of geographic applications.
• …applicable to geographic datasets, dataset series, and
individual geographic features and attributes
• ...may be used for other forms of geographic data such as
map, charts, textual documents
Developed following
the ISO Process
• Formal Process
–Refined over 50 years
–Stages and timelines fully defined
• Consensus based
–Drafts considered until consensus
reached through voting process by
P- members

Implementation Specification
• ISO 19115-2 Geographic Information
– Metadata – Part 2 Extensions for
Imagery and Gridded Data
ISO/TS 19139
Scope
This implementation specification is applicable to digital
geographic datasets and can be used to describe many
other forms of geographic data such as maps, charts,
and textual documents. It provides information about
the identification, the extent, the quality, the spatial and
temporal reference, and the distribution of digital
geographic data.
More specifically, this specification provides an
implementation UML model based on the ISO 19115
abstract UML model and defines an XML schema
derived from the implementation UML model.
