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

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?

Possible Basis for Cascading Menu in SERVIR

• Dataset Hierarchy

• Dataset Faceted Search

• Maproom Faceted Search

• Maproom Hierarchy

Generalizing the IRI plugin

• Making better use of WMS– Should separate out the layers– Transparent Background on Images– Could include local info references within
