  9. IRI Map Room

  10. 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

  11. 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

  12. IRI Map Room MEWS Time Series Analyses

  13. IRI Maproom • Maproom link • Global • Regional • Applications • Health • Food Security • Fires • IFRC

  14. Finding the Data and Maps • Semantic Web metadata/navigation/provenance http://iridl.ldeo.columbia.edu/ontologies/

  15. Faceted Search http://iridl.ldeo.columbia.edu/ontologies/query2.pl?...

  16. Metadata Browser http://iridl.ldeo.columbia.edu/ontologies/browse.pl

  17. Generalizing the IRI plugin • Currently entities are a view plus (optionally) a set of local data views • Local view is click-on-map plus some parameter choices • Would be good to generalize those parameter choices • Parameter choices should only appear when appropriate

  18. Generalizing the IRI plugin • Currently entities are selected from a cascading menu • IRI should serve that menu • Menu should be generated in a meaningful way • Do we need to consider some other way?

  19. Possible Basis for Cascading Menu in SERVIR • Dataset Hierarchy • Dataset Faceted Search • Maproom Faceted Search • Maproom Hierarchy

  20. Generalizing the IRI plugin • Making better use of WMS • Should separate out the layers • Transparent Background on Images • Could include local info references within WMS
