Large surface displacements measured with feature tracking

Challenge Description

When the surface deformation due to seismic events, volcanic activity, glacier motion, and/or slope instability is too large (meters or tens of meters) radar interferometry cannot be used due to decorrelation of SAR signal. In this case, feature tracking techniques can be applied. These approaches are convenient because they can be applied in a very similar way to different data sources, as for example optical and radar imagery. The aim of this challenge is to implement ad-hoc feature tracking algorithms to be applied to Sentinel-1 (radar) and Sentinel-2 (multispectral) satellite imagery.

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
