IPRO’s Pellucid database contains data for many quality of health care measures in counties, states, hospitals, and hospital regions. We designed the map to be fully driven by this database for both data values and metadata. Any changes made by staff are instantly reflected on the map, without the need to update the code.
The central design challenge was to make a map that can support any number of variables for different levels of geography and different types of geometry (points and areas), all without being overwhelming and confusing to the user. We designed an interface that is fairly simple for basic usage but can grow more complex if the user dives deeper by adding overlays, zooming to a street-level map, or changing symbolization options.
