Canadian Context
•
•
•
Large nation:
– sparsely populated
– remote and difficult access to many regions
Maritime nation:
– 3 oceans
– longest coastline in the World – 243,000 km
Polar nation:
– the Arctic is a government priority:
▪ a development challenge for Canada
▪ mapping polar shelf in support of UNCLOS
▪ increased maritime surveillance and arctic
science
– sensitive and rapidly changing environment
•
Large development, stewardship, security
responsibilities
•
Resource-based economy:
– natural capital, transportation, environmental
impact
•
Sustainable growth a challenge:
– observations and knowledge are tools to
sustainable growth

System (WIGOS): passive and
active terrestrial, airborne, and
spaceborne sensors working in the
visible, IR and microwave bands
WMO Information System (WIS):
collected data is exchanged freely
and in near real-time globally

Recognition of the Importance of
Earth Observation at WRC-12
• ITU Secretary-General Hamadoun Touré
•
commended the delegates on the attention given to
Earth observation radiocommunication
applications, which are crucial for monitoring and
combating climate change and for disaster
prediction.
WRC-12 agreed to Resolution 673 (Rev.WRC-12)
called “The importance of Earth observation
radiocommunication applications”.
Why is Earth Monitoring Important?
• Understanding
natural environment
Hydrometric Monitoring on
West Coast
• Assessing impacts
• Managing risk
in societal benefit
areas:
Over 80% of all
disasters in Canada are
driven by changes in the
environment

QUALITY HEALTH INDEX
• Empowers individuals to
decide how they might be at
risk
• Provides health messaging
for Canadians—both general
& at-risk populations—how
to minimize that risk
• High resolution landuse EO
needed to assess emissions
and impacts on air quality

Conclusions
• Communications/Broadcasting is not the only critical service in case of
disasters:
– Earth Monitoring is the essential tool for prediction, detection and
response to natural and man-made disasters. The data management
(including quality assurance and archive) of these transmissions is an
additional important challenge
▪ Earth Monitoring data is continuously used to forecast significant
events and thus provide early warnings to identify risks and reduce
impacts on life and property (e.g. floods, severe weather, chemical
releases)
▪ Earth Monitoring data is required before, during and immediately after
a disaster to assess risks and to ensure safe and effective operations
and to aid in planning (e.g. forecasting weather conditions during relief
operations)
▪ Earth Monitoring data analyses provide information to policy and
decision makers on the adoption of longer term mitigation measures
(e.g. modifying building codes to adapt to climate change)
– It is critical to provide and protect necessary spectrum, as well as radio
and telecommunication infrastructure, for obtaining and disseminating
