Custom Processing

ALOS-1 PALSAR    The L1.1 (SLC) custom processing service has been discontinued. ASF is in the process of becoming a mirror of the JAXA archive for PALSAR L1.1 products, so will soon provide worldwide coverage. If you are currently not able to find L1.1 products using Vertex or the ASF API, keep checking as new products are added to our archive daily.

Sentinel-1     ASF HyP3 (pronounced “hype”) is a user service for processing Synthetic Aperture Radar (SAR) imagery that addresses many common issues for users of SAR data:

  • Most SAR data require at least some processing to remove distortions before they are analysis-ready
  • SAR processing requires a lot of computing resources
  • Software for SAR processing is complicated to use and can be prohibitively expensive
  • Producing analysis-ready SAR data is hard to learn

HyP3 On Demand Radiometric Terrain Correction (RTC) and Interferometric SAR (InSAR) processing using GAMMA software are available through the ASF Vertex Data Search application. This allows you to use the powerful search tools of Vertex and then directly order data for processing without leaving the application. Processing is done in the cloud and results are available to download in less than an hour. 

Step-by-step instructions for using the Vertex On Demand processing services are available in the On Demand User Guide or the RTC On Demand! and InSAR On Demand! StoryMaps.

GAMMA RTC and InSAR processing are also available programmatically using the HyP3 API and HyP3 SDK. Detailed information about what these services provide and how to use them can be found in the ASF HyP3 User Guide.
