On Demand Sentinel-1 Processing in Vertex

The Alaska Satellite Facility offers On Demand processing of Sentinel-1 datasets to Radiometric Terrain Correction (RTC) or Interferometric SAR (InSAR) products through Vertex, ASF's Data Search web portal. You can submit scenes to be processed into higher-level products, avoiding the cost and complexity of performing such processing yourself.

On Demand Sentinel-1 products are generated using ASF's HyP3 processing platform, leveraging GAMMA Software. Products are distributed as UTM-projected GeoTIFFs. To learn more about the finished products, refer to the Product Guides:

Getting Started

To request On Demand products, visit ASF Data Search - Vertex.

  1. Select your scenes - RTC processing is available for Sentinel-1 GRD-H and SLC scenes with a beam mode of IW. InSAR processing requires pairs of IW SLC scenes. Use the Geographic Search in Vertex to find individual scenes to submit for RTC processing, or reference scenes to use for generating InSAR pairs. For InSAR, once you find a reference scene, use either the Baseline or SBAS Search to find scene pairs to submit for processing.

  2. Submit your request - After selecting your scenes, access the On Demand queue to submit your processing request. You may process jobs worth up to a total of 10,000 credits per month. See our Credits page for more details.

  3. Monitor your request - The On Demand Products search type displays your running and completed requests. New requests are typically available for download within an hour, but wait time will depend on processing load.

  4. Download your data - Finished On Demand products can be downloaded after an On Demand Products search either directly or via your download queue . On Demand products are retained and available to download for two weeks after processing.
