Publication of official Burst ID Maps

Microwave Toolbox
#1

Sentinel-1 performs systematic acquisition of bursts in both IW and EW modes. The bursts overlap almost perfectly between different passes and are always located at the same place. With the deployment of the SAR processor S1-IPF 3.4, a new element has been added to the products annotations: the Burst ID, which should help the end user to identify a burst area of interest and facilitate searches. Now, we publish complementary auxiliary products, the Burst ID maps.

The maps have a validity that covers the entire time span of the mission and they are global, i.e., they include as well information where no SAR data is acquired. Each entry of the database contains information about burst and sub-swath IDs, relative orbit and burst polygon, and should allow for an easier link between a certain burst ID in a product and its corresponding geographic location.

The maps are public and can be freely downloaded here: Sentinel-1 MPC Test data sets

The content is provided in sqlite3/spatialite binary (one per mode) and KMZ (one per mode and relative orbit number) formats. Additionally, a README file gives a description of the information provided by the maps, as well as information on the validation procedure and quality statistics.

Thank you for releasing this information. What would be the best document to cite for this map?

Thanks for sharing!

It would be great if this would be a first step towards the downloading of the desired bursts and not full-size products. Do you know if are there any plans for that?

Hi,
For now you can cite the map as follows:

Sentinel-1 Burst ID Map, version 20220530, generated by the SAR-MPC service, available on Sentinel-1 MPC Test data sets

At the moment there is no specific description available for the burst ID map generation, except for the very brief info in the README included with it. We are considering to prepare a short tech note on this.

The information on the generation of the burst ID itself can be found in the L1 Detailed Processing Model (ATBD) available in Sentinel Online and that can be cited.

We agree that this would be a very interesting feature from the Data Access Service and/or Snap, and it is acknowledged by the ESA ground segment management.
However, I interact here as part of the SAR Mission Performance Cluster (SAR MPC). This download feature is out of the scope and responsibilities of the MPC and has to be confirmed/implemented directly by those services
