Examples for standards

ISO 19115-1 “Metadata – Part 1: Fundamentals“

OGC City Geography Markup Language (CityGML) Encoding Standard

TIFF 6.0 Perspectives on Standards

Linguistic perspective and types of standards de-jure standard (French “la norme”, German “die Norm”)

Companies develop industry standards: de-facto standard

IT-business and geomatics, consortia of companies ensure interoperability: Also de-facto standards

Economic perspective

Standardisation avoids the costs

Participation in the standardisation process puts companies ahead of others

Standards enable a company to utilise a range of suppliers Standards support the legislation process User’s perspective

If technology is mature, then users expect standardised solutions that are simple, fast, and effective. Example: GeoTIFF

System manufacturer’s perspective

Government agencies and other customers have forced the manufacturers to open their systems and support standardised interfaces. If standardisation is pushed towards an implemented solution the companies not only have to pay for drafting the standard’s documentation but also for Programming the implementation.

Development group’s perspective

In the IT-domain, standardisation is very closely related to the design of computer systems. Choosing the right moment to launch a standard development is probably the most critical decision in the process. National perspective

The principles of standardisation are: do it once, do it right, do it internationally.

Hierarchy of standards

Usually the IT-domain recognises three levels: abstract, implementation, and interface. Classification of standards

Top level Bottom level Explanation

Level of coverage International Multinational, Regional National Local

Level of Recommended practice advisory document prescriptiveness Information report informative document

Standard, normative documents Technical specification Classification of standards

Top level Bottom level Explanation

Function Design standards focus on user consistency in respect to product structure and appearance. Examples: zip-codes and metadata.

Interface standards Example: communication protocols

Framework standards foundations of multiple products and services Examples: metric system, Coordinate Reference System

Performance standards results oriented and do not specify how to do it. Example: braking distance

Testing methods provide consistent and replicable methods for assuring quality and compliances. Examples: crash tests, conformance testing

Terminology creates agreements on what words mean, accelerating contracting and minimizing confusion Classification of standards

Top level Bottom level Explanation

Development De-facto standards arise from market forces; process most successful when dominant participants can “dictate” standards; also help speed the entry of smaller competitors, especially when standards are open and not proprietary

Regulatory standards by public agencies through rule-making; best for public safety and health or emission standards for automobiles

Consensus standards either voluntary agreements or set via Standards Developing Organisations (SDOs) like ISO Terminology of standardisation

ISO, CEN standards

OGC de-facto standards, industry standards

Legal force of standards

State-of-the-art

The application of a standard is not compulsory

A standard is binding, if it is said so in a contract

Often standards are referenced by laws 2 Organisations Standardisation organisations

Three formerly separate standards ISO 19113 “Quality principles”, ISO 19114 “Quality evaluation procedures”, and ISO/TS 19138 “Data quality measures”

Project lead: Sweden

Quality principles The “data quality elements” contain quantitative quality information.

Completeness Negative example: missing road data

Logical consistency The application schema distinguishes between public and private houses. The dataset distinguishes between low and high buildings.

Spatial accuracy The absolute point accuracy is 10 cm (diagonal)

Temporal quality The date of the data compilation was August 2010.

Thematic accuracy Areas have been classified according to remotely sensed imagery as meadow although, in reality, they were swamps.

Usability A product specification fully applies for the intended purpose. However, the data are 12 years old. Data quality (ISO 19157)

Quality measures Completeness Commission C.1 excess item indication that an item is incorrectly present in the data

C.2 number of excess items number of items within the dataset that should not have

been in the dataset

C.3 Rate of excess items number of excess items in the dataset in relation to the number of items that should have been present

C.4 number of duplicate feature instances total number of exact duplications of feature instances within the data

Omission C.5 missing item indicator that shows that a specific item is missing in the data C.6 number of missing items count of all items that should have been in the dataset and are missing C.7 rate of missing items number of missing items in the dataset in relation to the number of items that should have been present

Similar quality measures for other quality principles Spatial referencing by coordinates (ISO 19111)

Spatial referencing by coordinates – Extension for parametric values (ISO 19111-2)

Geodetic codes and parameters (ISO 19127)

Well known text representation of coordinate reference systems (ISO 19162) Spatial referencing by coordinates (ISO 19111)

A Coordinate Reference System may be geodetic vertical engineering image

Subtypes of Coordinate Reference Systems derived projected compound Spatial referencing by coordinates (ISO 19111)

Coordinate System subtypes Spatial referencing by coordinates – Extension for parametric values (ISO 19111-2)

Combination of a horizontal spatial Coordinate Reference System with a non- spatial third dimension, e.g. the "pressure altitude" in aviation.

Geodetic codes and parameters (ISO 19127)

Supported by NATO Well known text representation of coordinate reference systems (ISO 19162)

Well Known Text (WKT) offers a compact machine- and human-readable representation of geometric objects, including Coordinate Reference Systems.

The EPSG Geodetic Parameter Dataset is a collection of definitions of coordinate reference systems and coordinate transformations

Origin: European Petroleum Survey Group (EPSG), UK

Today maintained by IOGP, International Association of Oil and Gas Producers

Adopted by the Open Geospatial Consortium in 2001

Developed by Roger Lott, UK NTv2, National Transformation, version 2

De facto standard for the transformation of geospatial data from one coordinate reference system to another

Developed by the NRCan’s Geodetic Survey in the mid-nineties

2D

Two Austrian institutions – Bundesamt für Eich- und Vermessungswesen and Technische Universität Wien – have indicated an interest in extending the NTv2 to the third dimension.

Recent attempts and results at other places: • Inefficient mechanism for vertical data storage and access • New format is required, with many of the attributes of the NTv2 file structure

Involved experts: Roger Lott, UK, Mike Cramer, NRCan/Can., Dave Danko, Esri/USA, Keith Ryden, Esri/USA. Land Administration Domain Model (LADM, ISO 19152)

Intention: Help building modern property cadastre systems In particular in those countries which do not have a century of cadastral tradition

Structure: Abstract, conceptual schema with five basic packages (1) parties (people and organizations), (2) rights, responsibilities, and restrictions (ownership rights), (3) spatial units (parcels, buildings and networks), (4) spatial sources (surveying), and (5) spatial descriptions (geometry and topology)

Project lead: The Netherlands Preservation of digital data and metadata (ISO 19165)

Preliminary works:

ISO 14721:2012 “Space data and information transfer systems – Open archival information system (OAIS) – Reference model”

GI+100: 16 principles for the archival of geospatial data, published by the European National Mapping and Cadastral Agencies:

Archiving of digital Geographic Information begins at the point of data creation, rather than at the point of withdrawal from active systems (1).

Be selective and decide what to archive and what to lose (3).

Consider preservation timeframes of 1, 10, 100 years (4).

Geographical data should be preserved in a way that non geo-specialists can handle (8). Preservation of digital data and metadata (ISO 19165)

Earlier standard: Space data and information transfer systems – Open archival information system (OAIS) – Reference model (ISO 14721)

Input: Submission Information Package (SIP) Storage: Archival Information Package (AIP) Output: Dissemination Information Package (DIP) Preservation Principles of the ISO 19165

Prioritization Proposed categories 1 year, 10 years, 100 years, more

Data formats Format registry

Database Persistent understanding of the technology for accessing this dataset.

Properties Assumptions about the future potential use of the data

Level of aggregation Which levels of detail are required for archival?

Gold copy To increase reliability, copy in an open format

Intellectual property rights Authoritative geospatial data often possess legal restrictions (copyrights, authority to modify representation, agreements with external organizations)

Time Many geospatial data are continuously updated such as cadastral data (time slices)
