Abstract OnEarth is an open source software package that efficiently serves georeferenced raster imagery with virtually zero latency, independent of image size or spatial resolution. The key to OnEarth's speed lies in the use of a unique, multi-resolution file format (Meta Raster Format, or MRF) combined with supporting open source software packages such as the Geospatial Data Abstraction Library (GDAL) and Apache to serve out images via web service protocols such as Web Map Tile Service (WMTS) and Tiled Web Map Service (TWMS), or visualization formats such as Keyhole Markup Language (KML). The emphasis on performance and scalability were strong drivers for developing this specialized package versus using existing software.While OnEarth is currently deployed operationally at several institutions, powering applications across the Earth Science and planetary spectrum, its active development is managed by NASA's Global Imagery Browse Services (GIBS) project. The purpose of GIBS is to provide a complementary historical and near real time (NRT) image archive to NASA's Earth Science data products for a multitude of uses: GIS ingestion, first responder and NRT applications, data search and discovery, decision support, education and outreach.Released as open source to GitHub in October 2013, NASA is encouraging members of the open source community to participate in the evolution of OnEarth—in the roles of developers, evaluators, and users—as a means to vet and enhance its capabilities. This leveraging of efforts not only benefits those who intend to use the software for their own endeavors, it effectively contributes back to NASA by strengthening GIBS and promoting the use and understanding of NASA's vast archive of science imagery and data. Several tools, including the GIBS reference client, Worldview, will be demonstrated as part of this presentation to illustrate the breadth of application and consistent image access speed across installations.https://github.com/nasa-gibs/onearth
