The goal of ISO/TC 211...
... is to develop a family of international standards that will





support the understanding and usage of geographic information
increase the availability, access, integration, and sharing of
geographic information, enabling the interoperability of geospatially
enabled computer systems
contribute to unification of efforts to address global ecological and
humanitarian problems
ease the establishment of geospatial infrastructures on local, regional
and global levels
contribute to sustainable development

 19100
series
A structured set of standards for information
concerning objects or phenomena with locations
relative to the Earth
 Specifies methods, tools and services for
management of geographic information



Including the definition, acquisition, analysis, access,
presentation and transfer of such data
Over 50 projects; 40 have been finalized as ISO
standards or technical specifications

Adaptable through use of profiles
Highlights of 191XX Standards
 Architectural
Reference Model (ISO 19101)
Describes computational services to manipulate
geographic information in a distributed processing
environment
 Presents Enterprise, Informational, Computation,
Engineering Viewpoints

 General
feature model (ISO 19109)
Meta-model for developing conceptual models
 Types, attributes, associations and operations for
“features” (abstractions of real world phenomena),
defined in feature catalogs (19110)
 Also covers application schema

More 191XX Standards

Metadata (ISO 19115)


Encoding (ISO 19139)



Widely adopted in earth observation community
XML schemas for describing, validating and exchanging
metadata
19128 (WMS), 19136 (GML), 19142 (WFS) inherited
from OGC
Others


19117 – portrayal, 19118 – encoding, 19119 - services
Also, standards for DRM, registry management, and quality
measures
IPCC, UNEP, UNFCCC, GTOS and ECVs

The UNEP (United Nations Environment Program) and the
WMO (World Meteorological Organization) created the
IPCC (Intergovernmental Panel on Climate Change)


To assesses the scientific, technical and socio-economic
information necessary to understand the risk of humaninduced climate change
GCOS (Global Climate Observing System) was created
to ensure that observations and information
necessary for addressing climate change are
available.

Includes GOOS, GTOS, GAW, GCW
Essential Climate Variables
 GCOS
has identified 47 Essential Climate
Variables (ECVs)
Determined to be technically and economically
feasible for systematic observation
 Need to be accurately measured and systematically
monitored
 Of the 13 Terrestrial ECVs, most are globally
distributed and can be represented as coverages

 The
ECVs encompass many domains and
measurement protocols
UNFCC’s Request to GTOS

In 2006 the UNFCCC (United Nations Framework
Convention on Climate Change) the SBSTA (Subsidiary Body
for Scientific and Technological Advice) called on GTOS to:



“assess the status of the development of standards for each
of the essential climate variables in the terrestrial domain”
The UNFAO is working with TC211 to develop
standards for the representation one of the
terrestrial ECVs – Land Cover
GEO Task CL-06-03: Develop intergovernmental
mechanisms for coordinating terrestrial
observations needed for climate studies and
forecasting.
19144 – Classification Systems
 Part
1: Classification system structure
Based on discrete coverages and classification
rules maintained in registry
 At DIS stage

 Part
2: Land Cover Classification System
FAO/UNEP Land Cover Classification System
 Conceptual Basis for land cover description and
Registration of Classifiers
 Did not pass vote to advance to DIS, being revised

LCCS
 Provides
a scale independent method of
classifying land cover
 Uses a set of diagnostic criteria to
successively refine land cover features
 Approach is generic and supports all types
of land cover and accommodates all
existing classification systems
 Goal is to create an absolute level of
standardization between different land
cover classification systems
ISO Joint Steering Group
 ISO
will establish Joint Steering Group for
ECVs to support the UNFCCC’s mandate
The JSG will determine which ISO committee or
liaison organization will create each required
standard
 Expected to happen at TMB September 2008

 It
is possible that the JSG will ask bodies
like the IEEE for technical advice

Leary of undue influence from industry
The Standards Coordinating Committee for
Earth Observations (SCC 40)
 Created
to oversee the development of
standards essential to the functioning of
GEOSS (Global Earth Observations System of Systems )

Includes standards related to sensor systems,
communications, data processing, data archiving,
data searching and access, data portrayal and
decision support systems
 Type
2 - can sponsor a standards
development effort involving multiple IEEE
technical societies
 Approved by the Standards Board 3/2006
SCC 40
 The
ICEO has taken a leadership role in
facilitating standards and interoperability
for GEOSS

Current SCC40 membership is 8 volunteers
working on GEOSS-related standards projects
 IEEE
members are also working to support
The ICEO Standards Working Group
 The GEO Standards and Interoperability Forum
 The GEOSS Standards Registry
 The GEO Interoperability Process Pilot Projects
