A newly initiated campaign marks an important step in preparing for how data from the Sentinel-1 European Radar Observatory will be used for applications such as land-cover mapping and crop management. Sentinel-1 is the first of the five missions that ESA is developing for the GMES initiative.
Sentinel-1 is a constellation of two C-band radar satellites that will provide continuous all-weather, day and night imagery for use in a range of diverse services from marine and land monitoring to emergency services needed immediately following disasters from natural events, as well as those resulting from human activity. The initial Sentinel-1 satellite is due to launch at the end of 2011 and will be the first mission dedicated to providing Earth observation data for the Global Monitoring for Environment and Security (GMES) initiative. GMES is a joint venture between the European Commission and ESA to fulfil the growing need for accurate and timely information to better manage the environment, understand and mitigate the effects of climate change and ensure civil security.
The objective of the current campaign, called AgriSAR, is to evaluate how frequent multi-polarisation acquisitions provided by Sentinel-1 will improve applications such as land-cover mapping and crop monitoring. To accomplish this ambitious task, ESA has asked MDA Geospatial Services to acquire multi-temporal, quad-polarisation RADARSAT-2 imagery throughout the 2009 growing season over three test sites. The chosen sites are located in Flevoland in the Netherlands, Barrax in Spain and Indian Head in mid-west Canada. MDA Geospatial Services will be able to simulate various imaging modes for the Sentinel satellites from the series of images acquired during the campaign.
"The campaign is remarkable in that it will, for the first time, include very frequent spaceborne radar images over three different test sites throughout the growing season and thus provide an excellent
