1. 1 EOSDIS Global Browse Tools and Services Ryan Boller February 7, 2012 LANCE User Working Group Meeting Washington D.C.

2. 2 Driving Goal Provide full resolution product viewing capability for EOSDIS products; LANCE NRT products are being used as a pathfinder for a more general capability Approach Provide standardized services for brokers to pull and host or build their own interfaces to NRT imagery Provide a full-resolution, global browse tool that use the above services Global Browse Tools and Services

7. Imagery Server Trade Study Map / imagery server needed –Low latency for quick ingest of new products –Responsive for user interactivity –Flexible to support a variety of clients –Scalable to user demand and additional products Trade study with Physical Oceanography Distributed Active Archive Center (PO.DAAC) at NASA / JPL –Tiled Web Mapping Service (TWMS) –Google Earth Enterprise –Statically-generated Keyhole Markup Language (KML) files 3/20/2016NASA Land Atmosphere Near-real-time Capability for EOS (LANCE) 7

8. Imagery Server Trade Study 3/20/2016NASA Land Atmosphere Near-real-time Capability for EOS (LANCE) 8 Not a “black box” - can be evolved Compatibility with many clients: Google Earth, Google Maps, OpenLayers, NASA/ARC World Wind, others

9. System Architecture - Status Product ingest –50+ global data products being continuously ingested and served –Latency from map tile generation: 10-90min per product Map serving performance –Concurrent users: 1000+ –Latency: ~0.5ms / request External users –One “external” partner: NASA/JPL State of the Oceans projectState of the Oceans –Others anxious: EPA, NGA, Vandenburg AFB, American Museum of Natural History… 3/20/2016NASA Land Atmosphere Near-real-time Capability for EOS (LANCE) 9
