Facilitating Centralized Access to Earth Science Imagery & Metadata with NASA GIBS
Abstract:NASA's Earth Observing System Data and Information System (EOSDIS)' Global Imagery Browse Services (GIBS) is a system that provides full resolution imagery from a broad set of Earth science disciplines to the public. Behind this service lies The Imagery Exchange (TIE), a workflow data management solution developed at the Jet Propulsion Laboratory. TIE is an Open Archival Information System responsible for orchestrating the workflow for acquisition, preparation, generation, and archiving of imagery to be served by the GIBS’ web mapping tile service, OnEarth.
Before GIBS & TIE, users could access this imagery & metadata only by making requests directly to different providers & DAACs. GIBS solves this problem by offering a centralized way to access this data. TIE provides GIBS a mash-up of data by supporting a variety of different interfaces, security protocols, and metadata standards that are found across different providers.
This presentation will detail the challenges we’ve faced during the implementation of this data mash-up, and will highlight our current efforts to make GIBS a robust resource for our scientific community.
