Maritime Surveillance

• Regular collection of data to support all aspects of risk assessment and disaster planning.
• Interferometric SAR analysis over large areas to detect shifting infrastructure.

• Reducing the risk of disasters.
• Preventing catastrophes such as oil pipeline ruptures and building colapses.
• Predicting hurricanes and cyclones.
• Predicting flooding.
• Predicting drought and forest fires.

InSar is a long-established and proven technique for mapping technique for mapping and monitoring subtle, 1 centimeter and smaller, changes in surface position, whether it be vertical movement of the surgace or structural movement through subsidence.

• Predicting flash floods through InSAR analysis of snow accumulating and melt.
• Wind speed and direction for hurricane monitoring.
• Soil moisture and land cover information for drought and forest fires.

• Improved forecasts for severe weather such as heavy rain or snow events, hail, tornadoes, damaging waves, and storm surge.
• Reducing loss of life and property from natural and technological disasters.
• Ability to issue advance warning.

RADARSAT-1 contributes to international hurricane monitoring through the Hurricane Watch program, whick is systematically acquires images of hurricanes whenever possible.

• Timely, up-to-date situational awareness in areas affected by disasters in support of search and rescue operations.
• Generating wide area coverage to map the extent of large flooded areas.
• Wildfire mapping during fire.

• Ability to make high-profile international contribution to organizations such as International Charter "Space and Major Disasters".
• Reduced loss of life and reduced cost of disaster management.
• More efficient allocation of resources during response.

RADARSAT-1 data has been successfully used worldwide to support disaster response efforts during events such as flooding, oil spills, volcanic eruptions and severe storms.

Timely, up-to-date situational awareness in areas affected by disasters in support of recovery and assessment activities.

• Effective use and deployment of critical resources.
• Faster damage assessment.

"Until the November 95 launch of RADARSAT, no affordable, reliable data source existed which could provide synoptic information for monitoring flood extent."
