Global catalogue of co-seismic deformation (2002-2010)

1st GeoHazards Challenge (GH1)

Challenge Description

ENVISAT satellite acquired SAR imagery during the period 2002-2010. Many earthquakes occurred during this observation time and the analyses performed have consolidated the DInSAR as an extremely important technique to map and characterize co-seismic deformation. However, the DInSAR analyses were performed relying on different software and parameters, thus results are heterogeneous. In this challenge produce a homogeneous catalog of co-seismic deformation associated with earthquakes with Magnitude >5 by relying on the Envisat ASAR dataset.

Results

The results below are divided into Software Repositories, Online Services and Data Products Repositories.
In case you would like to get in touch with us about specific results, please use the indicated reference codes (e.g. WFP-01-01-01).

 

Software Repositories

There are two categories of software repositories generated for the Challenge:

  • GitLab repositories are hosting the reference software code, for use by the team members of a challenge only (restricted access)
  • GitHub repositories are hosting the public software code (mirrors), for engagement and collaborative work with the broad community of software developers (public access)

Follow the links below to proceed to one or the other, and find an "Ellip Workflows (ewf)" software application implementing a data processing function.
You can adapt this software to your own context, commit a contribution to the related repository, or engage with the BETTER consortium to run it for a specific purpose (new area of interest, ...) by requesting Cloud resources to support (at) terradue.com

Description Software repository (private) Software repository (public mirror) Reference

Coseismic DInSAR: ERS / ENVISAT automated InSAR Module (CNES, ALTAMIRA), by Terradue

The application generates pre and coseismic interferograms of significative earthquakes of magnitude higher than 5, to assess changes from the coherence normalized difference maps.

Resources: CNES ALTAMIRA DIAPASON processor

Data Processing as-a-Service

There are two categories of "Data Processing as-a-Service" application packages created for the Data Challenge:

  • Data Processing Pipelines are controlling full EO data production campaigns, for use by approved members of a challenge only (authorized access),
  • On-demand Processing Services are controlling individual EO data processing jobs, also for use by the approved members of a challenge only (authorized access).

Follow the links below to proceed to one or the other, via a dedicated Geobrowser application providing web access to one or the other of the Data Processing services.
You can engage with the BETTER consortium to request authorized access via support (at) terradue.com

Data Product Repositories

There is a dedicated client App publicly available for the visualization of the data products resulting from EO data processing challenges.

The results can consist of:

  • Validation data: small amount of data products generated for approval by the Challenge promoter
  • Production campaign data: full-time series/collection of data products answering the Challenge promoter question about Earth Observation data being used to help solve global societal challenges
Description  Catalog entries (public) Data product repository (public) Reference
  • Validation data as of Feb.2020 (with ESA SNAP tbx)
  • AOIs: Central Italy and Iraq only
  • New setup (using the DIAPASON application) as of March 2020: world earthquakes with magnitude >5, for pre-seismic and co-seismic events from early 2002 to end of 2010
