Metadata key building block abstracting geographic knowledge

Metadata Key building block abstracting geographic knowledge

  • Data about data

    • Geographic area covered

    • Currency

    • Rules of use

    • Positional accuracy

    • Data dictionary

    • Means of encoding

    • Datum

    • Map projection

  • A Key interoperability technology:

    • Producers explain their product

    • Users learn about products

  • Non standard products can be understood

Iso 19115 2003 scope

ISO 19115:2003Scope

  • ...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

UC 2007 Tech Sessions


19115 2003 geographic information metadata

19115:2003 Geographic Information – Metadata

  • Defines metadata elements;

    • Provides a schema(UML);

    • Establishes a common set of metadata terminology, definitions (data dictionary);

Corrigendum summary

  • Corrects numerous spelling mistakes

  • Clarifies language (sentences)

  • Removes CRS and projection parameter information (use new ISO 19111) RS_Identifier still used to identify CRS used by a dataset

  • Corrects Bounding Box coordinates datatype (from “angle” to “decimal”)

      • defining the schema and additional metadata required for imagery and gridded data

  • Objective

    • Augment existing ISO 19115:2003standard - define the content and structure required to:

      • Describe geographic imagery and gridded data

      • Support the collection of natural and synthetic imagery and gridded data

      • Support exploitation of imagery and gridded data

Iso 19130 image sensor models for geopositioning

ISO 19130 Image sensor models for geopositioning*

  • Defines the geolocation information that the data provider must supply in order for the user to be able to find the geographical location of the data using a physical sensor model, true replacement model, or functional fit methodology.

  • Provides detailed sensor models and associated uncertainties for the following types of passive electro-optical (EO)/ infrared (IR) sensors:

    • frame,

    • pushbroom

    • whiskbroom.

    • A set of components from which sensor models can be constructed for other sensors.

  • Defines the metadata to be distributed with the observation data to enable user determination of geopositions from the observations,

Summary

Summary

  • Metadata is a basic element used to abstract reality

  • Metadata completes the “picture” allowing us to fully understand the information

  • Metadata provides a handle used for discovery

  • ISO 19115 provides internationally standardized metadata elements and a schema – semantic interoperability

  • ISO 19139 provides an XML Schema encoding for metadata – technical interoperability

  • ISO 19115-2 will extend the schema for imagery and gridded data

  • ISO 19130 standardizes sensor model descriptions, provides imagery metadata supporting geopositioning

  • North American Profile of ISO 19115 will soon replace the FGDC Metadata standard providing international interoperability tailored for North America
