Resolution vs. Spatial Coverage
• Medium (10m-class) resolution large-coverage systems: – Sensors: Current: ALOS-2; Sentinel-1; RADARSAT-2
Future: SAOCOM; NISAR; RCM; BIOMASS
– Transportation Infrastructure-Related Applications:
• Monitoring of background stability (e.g., subsidence; slopes)
• Assessing impacts of hazards (flooding; earthquakes)
• Large-scale (e.g., countywide) analysis of network stability
• High (1m-class) limited-coverage resolution systems: – Sensors: Current: TerraSAR-X; TanDEM-X; COSMO-SkyMed constellation
Future: PAZ SAR; COSMO-SkyMed 2nd Gen
– Transportation Infrastructure-Related Applications:
• Assessing stability of individual installations (e.g., bridge motion)
• Detecting of localized infrastructure threats (sinkholes; small landslides)
• As most X-band systems are high-res: Monitoring of road surface health

Other Ways To Get To SAR Data: The WInSAR Consortium
• Western North America Interferometric Synthetic Aperture Radar Consortium (WInSAR) (http://winsar.unavco.org/) – Free data access to WInSAR holding for members (UAF is a member; I am the representative (so
come to me))
– Mostly interested in monitoring tectonic motion
– Data from ERS-1/2, Envisat ASAR, TerraSAR-X, Radarsat
– Beyond these data holdings, WInSAR also manages TerraSAR-X and ALOS-2 data for its users
