Abstract
The National Institute of Standards and Technology (NIST) contracted TRE ALTAMIRA (TREA) for a historical Interferometric Synthetic Aperture Radar (InSAR) analysis to produce surface displacement measurements over a wide Area Of Interest (AOI) of approximately 709.6 square miles (1,838 km2) along the eastern coastline of Florida. The main scope of the study was to identify potential regional displacement trends affecting the area. TREA processed historical Sentinel-1 (SNT) imagery available over the AOI up to the end of January 2023, using its proprietary SqueeSAR® algorithm. Transects specifically required by NIST were also generated and attached to this document in Appendix 1. The current document constitutes the final Technical Report and includes a detailed description of the imagery (Section 2), an introduction to InSAR technology (Section 3), an overview of the SqueeSAR results obtained (Section 4), and the findings of the data analysis and interpretation (Section 5), which aimed to characterize and quantify observed trends in ground surface displacement across the AOI. The analysis and interpretation of the InSAR results was performed in collaboration with Exponent Failure Analysis (EX). This effort included "ground truthing" of the InSAR time series, identification of potential sources of error, and the documentation and evaluation of observed spatial and temporal data trends in the context of geological, hydrological, and anthropogenic conditions (primarily construction related).
