GeoCare Navigator adds cluster views, organization filters and ZCTA service-area tools

Kristine Treece, presenter, demonstrated recently added features in the Health Center Program’s GeoCare Navigator mapping tool during a guided online walkthrough.

Treece opened the session by advising new users to watch the introductory video, then showed the tool’s home screen and basic workflow. "What you're seeing now is the home screen of the GeoCare Navigator," she said as she began the step-by-step tour.

The demo highlighted a cluster visualization used at wider zoom levels to reduce map clutter: "These circles represent clusters, or groups of multiple health center service delivery sites, that are located close to one another," Treece said, illustrating a cluster example that represented 23 sites. Selecting a cluster brings up a cluster summary card and an option to "View Health Center Sites," which opens a list of the individual sites and the full site pop-up containing site name, organization name and grant number.

At roughly a 10-mile zoom level, Treece demonstrated that clusters disappear and a right-hand sidebar appears, listing each visible site with a site card that includes the health center, organization name, site address and grant number. She noted the interface shows a card indicator (for example, "2 of 10") where the first card is a cluster summary and the remaining cards are individual-site cards.

The update also includes color-coded site markers to indicate organizations, with a caveat that colors can be duplicated across organizations. To help users distinguish organizations, Treece introduced a new "filter by organization" control: "If I click filter by organization, I see a list of organizations that are currently visible at this map level in location," she said. Activating the filter grays out other organizations while keeping all sites clickable; the list updates dynamically as the user pans or zooms.

Treece demonstrated creating a service area using draw/select tools and clarified that GeoCare service areas are generated from ZCTAs (ZIP Code Tabulation Areas) or ZIP codes, which may also be uploaded to create a service area. She emphasized that, with the enhancement, the site card list and organization filter remain visible while a service area is selected, allowing users to filter, pan, and zoom without losing the selected service-area context.

She also pointed out that some markers may represent multiple separate sites that share the same address; users can flip through the cards using on-card arrows to view each site individually. Finally, Treece confirmed that the table view—where selected ZCTAs and columns can be managed—remains unchanged and that the print PDF report will continue to display the sites on the map with color coding by organization.

"This concludes our overview of the new features in GeoCare Navigator. Thank you," she said to close the demo.

The demonstration focused on user-interface and data-visualization improvements intended to help users locate and inspect Health Center Program service delivery sites; it did not announce changes to data content or reporting policies.
