3. Improving The Security Situation In Afghanistan With Earth Observation Technologies

Canadian Forces (CF) has deployed Joint Task Force Afghanistan (JTF-Afg) which is now serving a key role in the NATO-led International Security Assistance Force (ISAF) whose goal is to improve the security situation in Afghanistan and assist in rebuilding the country. During the seasonal flooding period of March 2008, the Canada Centre for Remote Sensing (CCRS) conducted timely and relevant analysis of floodwater extents over the South of Afghanistan using the Canadian Earth Observation Satellite RADARSAT-1. Used extensively in and out of ISAF, the water extent analysis performed by the CCRS and the derived products have been key to providing global situation awareness of and assistance to reconstruction efforts in potentially flooded areas. The fact that RADARSAT-1 was available for disaster response planning throughout the flash floods season was a confidence builder for the NATO ISAF mission as well as all the governmental and non-governmental agencies operating in the South of Afghanistan.

5. Ensuring a Cleaner, Healthier Environment: Generating Satellite-derived Products For The Monitoring Of Harmful Algae In The Lower Great Lakes and St. Lawrence River

It is only through a healthier environment that Canadians can create the quality of life and standard of living to which we all aspire. Continuing from the success of two past Canadian Space Agency (CSA) Government Related Initiative Program (GRIP) projects, Environment Canada (EC) will use Earth Observation (EO) data, especially MERIS, to (1) construct time-series of satellite-derived water quality over the lower Great Lakes and the both the St Lawrence River and associated fluvial lakes, (2) determine optical cross-section spectra appropriate to these inland waters with a particular emphasis on harmful algal blooms, (3) modify existing or develop new optical models/algorithms for use with MERIS sensor aquatic colour data. This new project is a collaborative effort between CSA's GRIP, EC's National Water Research Institute and the St. Lawrence Centre. This new initiative will benefits Canadians and is in line with the National Water Strategy and the St. Lawrence Plan. For more information, please contact Robert.bukata@ec.gc.ca, guy.letourneau@ec.gc.ca or guy.aube@asc-csa.gc.ca.

6. Gauging the Health of Canada’s Forests From Space

Pest outbreaks caused by insect defoliation and climate-related drought resulting in dieback of trembling aspen are important natural disturbance agents on Canada’s forests. Repeat severe defoliation and aspen dieback result in mortality, reduced growth rates, dead tree tops and loss of foliage, all of which will impact forest productivity, carbon stocks, and the forest’s ability to sequester carbon from the atmosphere. With the support of the Canadian Space Agency's (CSA) Government Related Initiatives Program (GRIP), Canada Centre for Remote Sensing (CCRS) and the Canadian Forest Service (CFS) established a joint project entitled "Gauging the Health of Canada s Forests: Accounting for Insect Defoliation and Dieback in the Indicators of Sustainability for Canadians". The goal of this project is to develop and demonstrate Earth-Observation based methods for consistent, timely and spatially precise mapping and monitoring of the location, extent and severity of insect defoliation and dieback disturbances. The resulting information products support Canada’s national and international reporting requirements on environmental and sustainable development indicators. For more information, please contact Paul.Briand (paul.briand@asc-csa.gc.ca) or Joost van der Sanden (sanden@nrcan.gc.ca).

7. Improving the Environment and Health of Canadians From Space: CCRS leads International Efforts On Satellite Climate Data Records

Threats to our environment are a clear and present danger that now confronts governments around the world. This is nowhere more evident than in the growing challenge of climate change. Our Government believes that action is needed now to ensure our quality of life. To strengthen Canada's role in developing satellite-based climate data records, the Canadian Centre for Remote Sensing (CCRS) hosted a meeting on "Measurement consistency for 1-5 km sensors (MODIS, ATSR, and AVHRR)" in Ottawa on June 4-5, 2008, under the auspices of the international Committee on Earth Observing Satellites (CEOS). The focus of the meeting was on the consistency between satellite optical sensors used in climate change studies. The meeting was attended by several groups from USGS, NASA Goddard Space Flight Center, NASA Langley Research Center, and US NOAA. The scientific expertise and unique satellite data processing technology developed at CCRS were recognized as key elements of future efforts to produce climate data records for other regions of the world. This initiative is a component of NRCan/ESS program "Enhancing Resilience in a Changing Climate" and is supported by CSA's Government Research Initiatives Program (GRIP). For more information, please contact Alexander P. Trichtchenko (trichtch@ccrs.nrcan.gc.ca).

11. Polar Ice Shelf Break-Up Seen From Space

Canada is a cooperating member of ESA and contributed to the development of the Envisat satellite. Wilkins Ice Shelf has experienced further break-up with an area of about 160 km² breaking off from 30 May to 31 May 2008. In February 2008, an area of about 400 km² broke off from the ice shelf, narrowing the connection down to a 6 km strip; this latest event in May has further reduced the strip to just 2.7 km. This animation, comprised of images acquired by Envisat’s Advanced Synthetic Aperture Radar (ASAR) between 30 May and 9 June, highlights the rapidly dwindling strip of ice that is protecting thousands of kilometers of the ice shelf from further break-up: www.esa.int.

12. Land Cover Information From Space: GeoBase Product User Needs Assessment

To help Canadians to adapt to our changing environment, governments need to better understand Land Cover changes. This is nowhere more evident than in the growing challenge of climate change. Earth Observation (EO) can play a major role in the land information world. This information is required by numerous public sector and private sector organizations and crucial for their operations and services. The GeoBase Steering Committee recently decided that Land Cover would be a priority map layer to add to the GeoBase portal (www.geobase.ca). As the first phase of the project to create a GeoBase Land Cover product, this User Needs Assessment (UNA) asked a wide spectrum of users about their needs for Land Cover information, in both the short and long term. Supported by the Canadian Space Agency's Government Related Initiatives Program (GRIP), the Canadian Forest Service (CFS) created EOSD (Earth Observation for Sustainable Development) to satisfy forest sector requirements, in cooperation with the provincial governments. Agriculture and Agri-Food Canada (AAFC) is currently producing a Land Cover product as part of the National Land and Water Information Service (NLWIS) to meet the agriculture sector needs, again in collaboration with the provincial governments. The currently planned GeoBase Land Cover product will build on the EOSD and NLWIS products and will add new Land Cover data for northern Canada from the Canada Centre for Remote Sensing. The Land Cover Community of Practice (LCCoP) was recently established as a national network of federal agencies undertaking sector specific Land Cover monitoring initiatives. DB Geoservices Inc worked with members of the LCCoP and the GeoBase program to inform users (coast to coast to coast) of the currently planned GeoBase Land Cover Product, and seek their views on the usefulness of this product and ways to improve it. They also asked for input on long term Land Cover monitoring Products. Several recommendations were made for both the short term and long term Land Cover products. This UNA was funded by GeoConnections and the report will soon be made public. For more information, please contact Ian Jarvis jarvisi@agr.gc.ca or Denis Genest dgenest@nrcan.gc.ca.
