Locations File

The locations that are rendered on the map are not dynamically constructed. Instead a GeoJSON-ish file is used. The file is publicly stored in a Google Storage Bucket and access when the app is opened.

Warning: The format of this file is likely to change

The DemoApp uses the geometry.coordinatesfield for plotting the data point. The link is also attached to the datapoint. When a point is clicked on the map the link is used to populate the Locations table.
