Solid Earth Science Data System for Exploration of Lithospheric Deformation in the Western US
Abstract
The primary objective of this project is to generate long-term consistent surface deformation Earth Science Data Records (ESDRs) by infusing science product generation, visualization, and manipulation tools and information technology, prototyped under NASA’s REASoN, ACCESS and SENH programs, into an end-to-end operational Science Data System. The products include geodetic daily position time series, crustal motion velocities, and strain and strain rate maps. These data products will be at the level just below interpretation. They will make scientific discoveries from EarthScope’s Plate Boundary Observatory (PBO) and other GPS networks more accessible to the broad community of geophysics researchers and students by providing them these data products through a science data portal with integrated product exploration and modeling tools. Data products and web-based modeling tool are made accessible through a portal called GPS Explorer (http://geoapp03.ucsd.edu/gridsphere/gridsphere) that allows scientific users to explore and manipulate these products and data sets in a workbench-like environment. The tools allow users to explore geophysical parameters in response to earthquakes and volcanic events within the PBO and greater western North America region. This IT system has been designed using modern IT tools and principles in order to be extensible to any geographic location, scale, natural hazard, and combination of geophysical sensor and related data. We have built upon open GIS standards, particularly those of the OGC, and have used the principles of Web Service-based Service Oriented Architectures to provide scalability and extensibility. We will present how we have brought this IT infrastructure and these product generation tools to a mature, flexible and expandable science data system.
