ASF HyP3¶
Alaska Satellite Facility's Hybrid Pluggable Processing Pipeline
HyP3 (pronounced "hype") is a service for processing Synthetic Aperture Radar (SAR) imagery that addresses many common issues for users of SAR data:
- Most SAR datasets require at least some processing to remove distortions before they are analysis-ready
- SAR processing is computing-intensive
- Software for SAR processing is complicated to use and/or prohibitively expensive
- Producing analysis-ready SAR data has a steep learning curve that acts as a barrier to entry
HyP3 solves these problems by providing a free service where people can request SAR processing on-demand. These processing requests are picked up by automated systems, which handle the complexity of SAR processing on behalf of the user. HyP3 doesn't require users to have a lot of knowledge of SAR processing before getting started; users only need to submit the input data and set a few optional parameters if desired. With HyP3, analysis-ready products are just a few clicks away.
Getting started¶
On Demand products processed by HyP3 can be requested quickly and easily, either by using a web interface or programmatically. These services are currently only available for Sentinel-1 datasets.
Web Access¶
ASF's Data Search Vertex portal provides a rich interface to explore Sentinel-1 acquisitions and find images to submit for On Demand processing. It also provides tools for selecting pairs and stacks for InSAR analysis.
Programmatic Access¶
Requesting and downloading On Demand products can also be done programmatically:
Public Visibility of Jobs¶
