Creating Geomap Reports

Visualizer Geomap displays data by geographic regions in a map format, typically as a heat map or with markers, for example Sales by State or Sales by Region.

To create a Geomap, you must provide:
  • One attribute, for example location, region, or city
  • One measure, for example sales, or quantity
They are required because the map uses the measure to determine color intensity or marker size.
There are important limitations while working with the Visualizer Geomap.

Geomaps work best with aggregated data and fewer than 500 data points. If you need to display more than 500 data points, use a third-party mapping tool and embed its charts in Birst.

Performance depends on the computer resources that you use, so start with a small number of data points and increase gradually.

When too many data points are plotted, Geomaps may slow down or become unresponsive.

Creating a Geomap report:

  1. From the Guided Mode menu select Geomap. When the default map displays and the Visualizer prompts you to add a measure and a Geoattribute.
    add measure and geoattribute
  2. Add a measure, for example Sales.
    add a measure
  3. In the left pane, set the Geomap Layer Type for the Sales measure.
    set the Geomap Layer Type for the Sales measure
  4. Pick a Layer Type, for example heatmap.
    Pick a Layer Type
  5. Return to the Subject Area. The Sales measure in the Chart Builder shows the heatmap icon.
    Return to the Subject Area.
  6. Add a Geoattribute, for example Orders > ShipCity.
    ShipCity

    Visualizer prompts you to associate a map with the attribute.

    associate a map with the attribute
  7. Click ShipCity.
  8. Click Maps and select one, for example, United States > States.
    click map and states

    Visualizer applies the Sales measure and the State attribute data to a heatmap.

  9. Hover over the map to see the data. Click a State to zoom. Use the zoom controls, "+" and "-" to resize the heatmap.
