  1. Global Agricultural Monitoring GLAM Team • Curt A. Reynolds (FAS) Edwin Pak, Amir Majedi, Jenn Small, Assaf Anyamba, & Compton Tucker (GSFC) • FEWS NET Science Meeting October 2-3, 2012 University of California, Santa Barbara Agricultural Drought: New Directions in Risk Assessment, Monitoring, & Forecasting

  2. GLAM Overview • Second generation MODIS-based agricultural system to support FAS monitoring activities • Successor to the Pekko system (@ UMD) – proof of concept ... • Improvements – wall to wall global coverage, rapid query, & simplicity • Currently classified as “Beta” but operational version – testing different component technologies, architecture and data base • Future improvements to follow when VIIRS data operationally ingested • Includes: • NRT production -- therefore operational • Two processing nodes set up (glam0 for USDA/FAS/IPAD, glam1 as fail-safe/other agency/public system) • Data: provides Terra and Aqua data (NDVI, NDWI) • GUI • Data query and plotting by Crop mask and administrative region • Capture AoI /current map view with visible crop and shape layers in PNG or JPEG formats. • Keyboard shortcuts to improve data set navigation and querying

  5. DB Results: Plot 1 After changing plot configurations, click [Update] to refresh plot image. All plots can be downloaded and saved offline

  6. DB Results: Plot 3 (Interactive) Dynamically enable or disable years or the mean Custom range scaling with tool-tip data point highlighting

  7. DB Results: Table download CSV format can be opened as text file or with any spreadsheet application

  8. Summary • Browser Compatibility – on going issue, but big strides have been made. Best viewed on Firefox/Chrome with at least a 1280 x 768 screen resolution - javascript engine outperforms IE. IE supported but slower: if user experiences IE problems, screenshots of the errors should be forwarded to Amir and Ed • Official release to FAS happened when GLAM0 was updated with the reprocessed dataset and running NRT production ~ 6/22: system was declared as an operational prototype. • The public release of the GIMMS GLAM (beta) system is now available and online at http://glam1.gsfc.nasa.gov/ • the public glam1 system runs about 6-12 hours behind the private • glam0 system on data production days under normal operations. This is to prioritize and balance system loads to ensure the highest performance for primary users (IPAD/FAS) on the glam0 system. •   Choice of MapQuest over Google maps is based on the legal terms of use: Open MapQuest has less red tape and is free to use and share under Created Commons. • For documentation on HTTP retrieval of GIMMS GLAM internal DB files, please see http://glam0.gsfc.nasa.gov/doc/README.http_db. This method may be used to access database tables outside the web browser user interface. •   For more information please visit: http://glam1.gsfc.nasa.gov/doc/home.html • User feedback to edwin.w.pak@nasa.gov: Please include error messages, screenshots, and steps to duplicate the problem.
