Breakthrough Research by NSI Remote Sensing Specialist Shows Coastline Entering New Recovery Stage

A paper authored by Dr. Arnob Bormudoi (First Author) and other two members of New Space Intelligence, Inc., has been published in the international remote sensing journal, Remote Sensing.

📰 Paper Abstract

This study provides a detailed analysis of the long-term recovery process of the Sendai coastline following the 2011 Tohoku Tsunami, utilizing satellite data.

Analysis Method: The research combined cutting-edge data analysis techniques, Dynamic Time Warping (DTW) and Persistent Homology (PH), to simultaneously quantify both the geometric changes and the structural complexity of the shoreline.

Key Finding: The study revealed that the Sendai coastline is not merely returning to its original state but is transitioning toward a "new dynamic equilibrium" characterized by increased structural complexity.

This research provides valuable insights that will contribute to future disaster prevention and environmental management efforts.
