Land Cover Change Detection with radar data

4th Geospatial Intelligence Challenge (GI4)
global-catalogue-of-co-seismic-deformation.jpg

Challenge Description

SAR sensors are a valuable tool to detect changes over man-made and natural structures: especially in equatorial regions, where clouds are present throughout the whole year thus limiting the use of optical sensors, SAR sensors could be used as a complementary source of information. The aim of this challenge is to create ready-to-analysis products for the identification of changes.

 

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

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

Description Data Processing Pipeline (private) On-demand Processing Service (private) Reference

Application package,
available for deployment as:

Data processing pipeline

  • Trigger App & coordinator, ready for production via Terradue Ops or via Ellip notebooks workspace for 'any' Scaler user)
  • No dedicated Geobrowser App available yet for Scaler users
  • Initial results from validation tests are available on the data Store

On-demand processing

  • Private access from dedicated Geobrowser available upon request, to authorized Scaler users.

For authorized users upon access request addressed to support (at) terradue.com. and after approval by WFP.

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
