Data Access
ARIA Product Search
InSAR standard data products are currently searchable and downloadable through Alaska Satellite Facility (ASF) DAAC Vertex. This site requires a NASA Earthdata URS user login.
Event Response
Data products that have been generated for event response are made available on the ARIA Share site, which does not require a login. The products are generated for both emergency response and scientific rapid response. These include Devastation (Damage) Proxy Maps, Water and Water Change Maps, Surface Disturbance Maps, Displacement Maps and time series for earthquakes, volcanic eruptions, and landslides.
