  10. IRI Map Room

  11. IRI Map Room Malaria Early Warning System • Front page illustrates most recent dekadal rainfall estimates (FEWS RFE) • Administrative and epidemiological overlays available • Change dates to view different time periods • Click and drag box across map to zoom

  12. IRI Map Room MEWS Time Series Analyses STEP 1: Select size of domain for analysis Administrative District OR Box – 11km, 33km, 55km, 111km STEP 2: Select location for which analysis will be created

  13. IRI Map Room MEWS Time Series Analyses

  14. IRI Map Room Climatic Suitability Interface • Front page illustrates number of months during the year that are suitable based on “normal” conditions • Same visual options as MEWS

  15. IRI Map Room Climatic Suitability: A Historical View

  16. IRI Map Room Connection Between Resources Links on the side menu allow users to interact between products

  17. IRI Map Room Connection Between Resources

  18. Going into the Future • Continuing data efforts • Expanding map rooms directed at particular user groups • Semantic Web metadata/navigation/provenance http://iridl.ldeo.columbia.edu/ontologies/
