Seamless Synthetic Aperture Radar (SAR) Archive for Interferometry Analysis

UNAVCO/WInSAR, the Alaska Satellite Facility (ASF), and JPL propose to collaborate in an information technology and data management development project to design and implement a seamless distributed access system for Synthetic Aperture Radar (SAR) data and derived data products (InSAR interferograms).

A seamless SAR archive will increase the accessibility and the utility of SAR science data to solid earth and cryospheric science researchers. Specifically, the project will provide simple web services tools to more seamlessly and effectively exchange and share SAR metadata, data and archived and on-demand derived products between the distributed archives, individual users, and key information technology development systems such as the NASA/JPL QuakeSim and ARIA projects that provide higher level resources for geodetic data processing, data assimilation and modeling, and integrative analysis for scientific research and hazards applications. The proposed seamless SAR archive will significantly enhance mature IT capabilities at ASFs NASA-supported DAAC and UNAVCOs WInSAR and Supersites archives that are supported by NASA, NSF, and the USGS in close collaboration with ESA/ESRIN.

As part of the proposed effort, data/product standard formats and new QC/QA definitions will be developed and implemented to streamline data usage and enable advanced query capability. The seamless SAR archive will provide users with simple browser and web service API access tools to view and retrieve SAR data from multiple archives, to place their tasking requests, to order data, and to report results back to data providers; to make a larger pool of data available scientific data users; and to encourage broader national and international use of SAR data. The new ACCESS-developed tools will help overcome current obstacles including heterogeneous archive access protocols and data/product formats, data provider access policy constraints, and an increasingly broad and diverse selection of SAR data that now includes ESA/ERS/ENVISAT (and upcoming Sentinel mission), CSA/Radarsat, JAXA/ ALOS-PALSAR, and DLR/TerraSAR-X satellite data and NASA/UAVSAR aircraft SAR data. The list will continue to expand with NASA/DESDynI further increasing the need to efficiently discover access, retrieve, distribute, and process huge quantities of new and diverse data.
