Map View

Your portfolio on a map

The Map View tab plots the clinical-trial sites of the trials currently in view. It reads each trial's geocoded site locations, so as you filter the dashboard (by query, phase, status, sponsor, disease, drug…) the map updates to show only the matching sites. A trial that runs at several sites appears at each one.

• Each point is a trial site (facility), positioned by its latitude/longitude.
• The map respects every other filter on the page, and a selection on the map filters the rest of the dashboard back.
• When you deep-link to a single trial, the map shows just that trial's sites; a "Show All Studies" button clears the single-trial focus.

Markers, clusters & heat map

At a world view, nearby sites collapse into colored cluster bubbles showing how many sites they contain; zoom in (or click a cluster) to break it apart down to individual markers. A toggle switches the same data between markers/clusters and a heat map that shades regions by site density.

• Cluster bubbles — count of sites in that area, colored on the same scale as the legend (more than 10 sites is red) and sized by the count.
• Legend — headed "Colour = count, on one scale": a pin's colour is the number of trials at that site, a numbered circle's colour is the number of sites in the group, both on the same bands (1, 2–5, 6–10, More than 10); purple marks a nearby site nudged apart to stay visible. In heat-map mode it shows the fewer-to-more-sites color scale.
• Markers — individual sites; click one for details (below).
• Heat map — toggle from the controls to see geographic concentration at a glance instead of individual points.

Draw a polygon to filter by geography

Use the draw tool to lasso an area and filter your whole portfolio to trials with a site inside it — useful for "trials running in my region/country cluster". Click Draw Polygon Filter, click the map to drop points (at least 3), then the check mark to complete it. The polygon filter stacks with all other dashboard filters.

• Draw Polygon Filter — start dropping points; until you have 3, the complete button's tooltip says how many more you need.
• Complete Polygon / Cancel Drawing — apply the polygon, or discard it while drawing.
• Redraw Polygon Filter / Delete Polygon Filter — replace the current polygon or remove the geographic filter entirely.
• While active, the dashboard, table, and the Facilities/Countries/Regions charts all narrow to sites inside the polygon.

Facility details

Click a site marker to open the Facility Details dialog: the facility name and city/country, the trial(s) running there with their status, and an Open in Google Maps button that shows the site in Google Maps. This makes the map a way to explore who is running what, where.

• Choose what the dialog shows with Popup Settings (the gear button in the map toolbar): tick NCT ID, Overall Status, Phase, Lead Sponsor and Study Details on or off, and optionally add one of your custom columns.

Map controls

• Zoom In / Zoom Out and pan; clusters expand as you zoom.
• Show Heat Map / Show Markers — switch between the heat map and markers.
• Draw, complete, cancel, redraw, or delete the polygon filter.
• Enable Location, then Center on my location — with your browser's permission, center on where you are to see nearby sites.
• Popup Settings (gear) — choose which fields the Facility Details dialog shows.
• Enter Fullscreen / Exit Fullscreen — expand the map to fill the screen.
• Tiles follow your light/dark theme.

Where the map data comes from

Sites come from each trial's location records (the ClinicalTrials.gov locations data), geocoded to coordinates. Only sites with valid coordinates are plotted. The same location data powers the Top Facilities, Countries Distribution, and Regions Distribution charts — and when a polygon is active, those charts use only the sites inside it.
