1 ISO/TC 211 Geographic information/Geomatics 1 Presented by Julie Binder Maitra At GSDI-7 Bangalore, India February 2004 नमस्ते ! Applying ISO/TC 211 Standards in the Development of Data Content Standards

2 ISO/TC Applying ISO/TC 211 standards in the development of data content standards Topics  ISO Standards of interest  ISO/DIS Geographic information — Rules for application schema (slides 3-5)  ISO Geographic information — Schema for coverage geometry and functions (slides 6-7)  ISO 19115:2003 Geographic information — Metadata (slides 8-10)  Application in development of data content standards  Introduction to Geospatial One-Stop (slides 11-12)  Standards developed through Geospatial One-Stop (slide 13)  Application of ISO standards of interest (slides 14-17)  Links (slide 18)

3 ISO/TC ISO/DIS Geographic information — Rules for application schema  Presents General Feature Model for defining geographic features  Provides rules for defining an application schema in Unified Modeling Language (UML)  Provides rules for integrating schemas from other ISO/TC 211 standards into an application schema for a complete data structure  Pending registration as Final Draft International Standard (FDIS); targeted for publication as an International Standard (IS) in May 2004.

4 ISO/TC ISO/DIS Geographic information — Rules for application schema Extract of General Feature Model

5 ISO/TC ISO/DIS Geographic information — Rules for application schema ISO/DIS provides specialized rules for integrating schemas from the following standards in the series of standards:  ISO 19115: 2003, Geographic information — Metadata (including data quality reporting)  ISO 19108:2002, Geographic information — Temporal schema  ISO 19107:2003, Geographic information — Spatial schema.  ISO/DIS 19110, Geographic information — Feature Cataloguing Methodology  ISO 19112:2003, Geographic information — Spatial referencing by geographic identifiers

6 ISO/TC  Defines coverage as a “feature that acts as a function to return values from its range for any direct position within its spatiotemporal domain.”  Data sets that can be represented as coverages include digital orthoimages, gridded elevation data sets, and thematic classification maps such as soils maps.  Coverages are of two types: discrete and continuous  Representation of geographic phenomena as discrete features or coverages is not mutually exclusive. A discrete feature or a coverage could represent the same phenomenon.  Pending registration as a Draft International Standard (DIS); targeted for publication as IS in May ISO Geographic information — Schema for coverage geometry and functions

7 ISO/TC ISO Geographic information — Schema for coverage geometry and functions Coverage geometry packages

8 ISO/TC The main package in ISO is Metadata entity set information. It is an aggregate of other packages: Identification information – information to uniquely identify a resource or resources Constraint information – restrictions on access and use of a resource or metadata Data quality information – scope, lineage (information about events or source data used to construct the data), and data quality element information. Maintenance information - scope and frequency of updating data. Spatial representation information - information concerning the mechanisms (grid or vector) used to represent spatial information in a dataset. Reference system information - description of spatial and temporal reference system(s) ISO 19115:2003 Geographic information — Metadata

9 ISO/TC Content information – information about the feature catalogue used and/or information describing the content of a coverage dataset Portrayal catalogue information - information identifying the portrayal catalogue used. Distribution information - information about the distributor of and options for obtaining a resource. Metadata extension information - information about user specified metadata extensions. Application schema information - information about the application schema used to build a dataset. Extent information – metadata elements that describe the spatial and temporal extent of the referring entity. Citation and responsible party information - data types for citing a resource (dataset, feature, source, publication, etc.) and information about the party responsible for a resource. ISO 19115:2003 Geographic information — Metadata (continued)

10 ISO/TC ISO 19115:2003 Geographic information — Metadata

11 ISO/TC Introduction to Geospatial One-Stop  E-Government (E-gov) Initiative  Component of President’s Management Agenda  Geospatial One-Stop is one of 24 E-gov initiatives  Objectives  Raise the visibility of the strategic value of geographic information and the National Spatial Data Infrastructure (NSDI)  Accelerate implementation of the NSDI  Increase Federal agency accountability for the stewardship and sharing of geospatial resources  Make access to geospatial information faster, easier and less expensive for all levels of government and the general public

12 ISO/TC Develop standards for data themes used by many different GIS applications. These themes are known as NSDI Framework themes. 2.Inventory existing Framework data holdings and create metadata to enable data discovery through the NSDI Clearinghouse. 3.Create metadata for planned data acquisition and update of Framework data and serve metadata through the NSDI Clearinghouse to enable opportunities for partnerships. 4.Prototype and deploy enhanced data access and web mapping services for Federal Framework data. 5.Establish a (One-Stop) Federal Portal providing web services to extend the capabilities of the NSDI Clearinghouse Network. Introduction to Geospatial One-Stop

16 ISO/TC Application of ISO Top Level Classes for Digital Orthoimagery

17 ISO/TC Application of ISO  Standards developed through Geospatial One-Stop will be compliant with ISO  Some elements listed as optional in ISO are mandatory for Geospatial One-Stop  examples: Metadata standard name, Metadata standard version, Dataset purpose, Dataset progress, Dataset maintenance and update frequency  ISO elements closely match elements in FGDC Content Standard for Digital Geospatial Metadata, FGDC- STD (version 2.0); therefore, data standards will be compliant with FGDC standard  FGDC standard lacks metadata elements for language and character set

18 ISO/TC Links  ISO Technical Committee 211, Geographic information/Geomatics,  Geospatial One-Stop,  FGDC Content Standard for Digital Geospatial Metadata, FGDC-STD (version 2.0),
