Why ISO Metadata What is ISO Metadata General Overview of ISO Content and Organization

Why ISO Metadata?

Executive Order Established the National Spatial Data Infrastructure (NSDI) to support public and private sector applications of geospatial data Established an electronic National Geospatial Data Clearinghouse for the NSDI to address data standardization, make geospatial data publicly available, and address redundancy and incomp atibility of geospatial information

OMB Circular A-16 Provides guidance for federal agencies that create, maintain or use spatial data directly or indirectly through the establishment of the National Spatial Data Infrastructure (NSDI) and the Federal Geographic Data Committee (FGDC) Establishes guidelines for the management of digital spatial data and the use of those assets. It also appoints the FGDC to the interagency coordinating body for NSDI-related activities

FGDC Endorsed Standards

What is ISO Metadata?

ISO Geospatial Metadata ISO – International Organization for Standardization Use the 191** series – ISO 19115:2003/Cor 1:2006 Geographic information - - Metadata ISO 19115:2003/Cor 1:2006 – ISO :2009 Geographic information -- Metadata -- Part 2: Extensions for imagery and gridded data ISO :2009 – ISO/TS 19139:2007 Geographic information -- Metadata -- XML schema implementation ISO/TS 19139:2007 – ISO 19110:2005/Amd 1:2011 Geographic information -- Methodology for feature cataloguing ISO 19110:2005/Amd 1:2011 – ISO 19119:2005/Amd 1:2008 Geographic information -- Services Extensions of the service metadata model ISO 19119:2005/Amd 1:2008

ISO Metadata Is flexible Depicts relationships between datasets and collection level (parent/child relationships) Standardizes descriptors through the use of codelists Accommodates new technologies (such as documenting services) Accommodates International scope Undergoes revision/review in 5 year cycles

Organization and Content of ISO ISO is organized in Sections and Packages Section: Groupings of similar information Package: Logical groupings of elements found in multiple locations within Sections

Main Sections of ISO Metadata Metadata Information (MD_Metadata) Root element that contains information about the metadata itself. Root contains main sections. Spatial Representation Information (gmd:spatialRepresentationInfo) geospatial representation of a resource Reference System Information (gmd:referenceSystemInfo) spatial and temporal reference systems used in the resource Metadata Extension Information (gmd:metadataExtensionInfo) user specified extensions to the metadata standard used to describe the resource Identification Information (gmd:identificationInfo) uniquely identify a resource or resources Content Information (gmd:contentInfo) physical parameters and other attributes contained in a resource Distribution Information (gmd:distributionInfo) who makes a resource available and how to get it Data Quality Information (gmd:dataQualityInfo) quality and lineage (including processing steps and sources) of a resource Portrayal Catalogue Information (gmd:portrayalCatalogueInfo) collection of defined symbols used to depict, to humans, features on a map Metadata Constraint Information (gmd:metadataConstraints) constraints on the use of the metadata and the resource it describes Application Schema Information (gmd:applicationSchemaInfo) application schema used to build a dataset Metadata Maintenance Information (gmd:metadataMaintenance) maintenance of the metadata and the resource it describes
