M/039 - Geographic information

To produce a set of definitions for use in standards developed in the field of geographic information.

To develop or adopt formal languages and graphical notations for defining and describing application data - including geometry directory and dictionary data. This includes the definitions of techniques for mapping from conceptual schemas to transfer schemas.

This European Standard defines the requirements of query and update of geographic information. It identifies the spatial operators that a standard data manipulation language shall use to process geographic information, and identifies the minimum requirements that the server and client shall agree to ensure that the integrity of the client database is maintained.

To provide an overview of the family of standards. To describe the areas of application to which the family applies. To explain the overall context within which the family will operate.

In the context of this European Prestandard, a direct positioning system identifies location of points in relation to the Earth by coordinates. The most widely-used systems are geodetic reference systems. Others exist, mainly for local use. This European Prestandard: - defines the basic concepts related to coordinate position information; - gives the guidance necessary to use the geodetic reference systems for geographic information. The choice of any particular position system is outside the scope of this European Prestandard.

This European prestandard establishes a conceptual schema for metadata. Metadata can be defined at its simplest as 'data about datasets'. This European prestandard specifies those data which shall be used to describe a geographic dataset. This includes data about the content, representation, extent (both geometric and temporal), spatial reference, quality and administration of a geographic dataset. This European prestandard also identifies those data which are mandatory for describing geographic datasets, the minimum set of metadata.

This European Prestandard specifies a method for the transfer of geographic data and their metadata. It defines the transfer schemas, implementation mechanisms and encoding rules for the transfer of geographic data. This European Prestandard supports transfer both for data defined by standardised schemas and for data defined by application specific schemas.

This European Prestandard establishes general principles for describing the quality of geographic information and provides a schema for describing data quality. This European Prestandard specifies information appropriate for the judging of quality of geographic information. This includes details of the derivation and usage of particular sets of geographic information and the results of measures of quality either against a pre-established scale or relative to similar information.

This European Prestandard establishes a schema for spatial referencing using geographic identifiers. It specifies how a system of geographic identifiers is described, and defines the attributes of a location and the contents of a gazetteer of locations. Spatial referencing based on coordinates is outside the scope of this standard. This European Prestandard is applicable not only to digital data, but also to other forms of geographic data such as maps, charts and textual documents.

This European Prestandard establishes principles for describing spatial schemas which can be part of application schemas. These schemas can be used for defining, structuring, querying, updating, encoding, transforming and transferring geographic data. The spatial schemas specify the constructs for the representation of geometry and topology of geographic objects. The constructs are defined in spatial schemas according to requirements from the applications.

This European Prestandard identifies and defines a structured set of concepts and components enabling the definition, the description, the structuring, the query and the updates and the transfer of geographic information and information about geographic information. This European Prestandard does not prescribe the use of any specific standard, it does not serve as an implementation specification for systems nor does it serve as a basis for appraising the conformance of implementations.
