Datasets SAR (Radar) associés
ALOS-2 PALSAR-2 (SAR)
JAXA
JAXA's L-band SAR satellite. Because it senses terrain change beneath vegetation, it excels at monitoring landslides and volcanic activity in forested areas. Emergency imagery during disasters is provided free of charge.
StriX (Small SAR Constellation)
Synspective (Japan)
A Japanese small-SAR satellite constellation. It offers 1 m-class resolution with day/night, all-weather observation, supports ground-displacement analysis and emergency disaster tasking, and pairs with analytics services.
ICEYE SAR (25 cm-class SAR)
ICEYE (Finland)
One of the world's largest SAR constellations. It reaches a top-tier 25 cm SAR resolution and has a strong track record in damage assessment for the insurance industry during storms and floods.
