Summary

Terradue, an ESA spin-off, is at the forefront of developing platforms and applications that aid researchers in extracting valuable information from the vast amounts of data generated daily by Earth observation satellites. By leveraging Elasticsearch technology, Terradue has created a query engine that efficiently selects optimal satellite acquisitions for InSAR applications, a technique used to map ground deformation via radar imagery. This capability was notably applied in assessing the aftermath of the 2015 Nepal earthquake. The process involves indexing extensive metadata linked to satellite imagery, encompassing acquisition properties, orbit state vectors, and tie points, allowing for rapid computation of satellite data pairings necessary for precise ground displacement measurements. Terradue's use of Elasticsearch facilitates real-time data processing, achieving significant speed and efficiency in querying and filtering satellite data, supporting geohazard research and broader Earth science applications. As Terradue celebrates its 10th anniversary, it continues to expand its cloud platform solutions, underscoring its commitment to advancing Earth sciences through scalable and innovative data processing technologies.
