Land Cover Change Detection with radar data

4th Geospatial Intelligence Challenge (GI4)


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.



The results below are divided into Software Repositories, Data Processing Pipeline Services and Data Product Repositories.  In case you would like to get in touch about specific results, please use the indicated reference code.


Software Repositories

There are currently two Software repositories in the area of Change Detection and Characterization: SAR Change Detection with GRD data. All of them available on request. GitLab contains the data. Follow the link below to proceed to the corresponding platform. To run this application you will need a Developer Cloud Sandbox that can be requested at support (at)

Data processing pipeline

There is a trigger App & coordinator, ready for the production via Terradue Ops or via Ellip notebooks workspace for 'any' Scaler user. There is no dedicated Infohub App available yet for Scaler users. Initial results from validation tests are available on the Data Store.


On-demand processing

Private access from dedicated Infohub App not yet available
