 How to create and use Maps in Power BI

Creating and Using Maps in Power BI

Power BI offers several ways to create and leverage maps for visualizing your data geographically. Here's a breakdown of the process:

1. Choosing the Right Map Visualization:

  • Basic Map: Displays data points (e.g., stores, customers) on a world map or specific region. Great for basic location visualization.

  • Filled Map: Colors different geographical areas based on data values (e.g., sales per country). Effective for identifying patterns and trends.

  • Shape Map (Preview): Lets you customize map boundaries to specific regions or shapes and color them based on data. Ideal for detailed geographical analysis.

2. Adding the Map Visual:

  • Go to the Visualizations pane in Power BI Desktop.

  • Select the desired map type (Basic, Filled, Shape Map).

  • The map visual will appear on your report canvas.

3. Binding Data to the Map:

  • Drag and drop fields from the Fields pane to the appropriate areas in the Format pane:

  • Location: Specify geographic field (e.g., country, city, latitude/longitude).

  • Color: Assign data field for coloring map areas (Filled Map, Shape Map).

  • Size: Define data field for sizing data points (Basic Map).

4. Customizing the Map:

  • Use the Format pane options to personalize your map:

  • Change map style (e.g., roads, terrain).

  • Add tooltips, legends, and titles.

  • Modify data point styles and colors.

  • Apply zoom and pan functionalities.

5. Interactive Features:

  • Power BI maps offer interactive capabilities:

  • Filter data: Clicking on map areas filters other visuals based on location.

  • Drill down: Clicking on data points can open detailed reports for specific locations.

  • Highlighting: Hovering over data points highlights them for clearer identification.

6. Advanced Techniques:

  • ArcGIS Maps (Pro version): Integrate rich geographical data and analytical tools from ArcGIS.

  • Custom Map Layers: Import custom map layers (e.g., company boundaries) for tailored visualizations.

  • DAX Measures: Create custom calculations for dynamic data coloring and filtering on maps.


  • Choose the map type that best suits your data and analysis needs.

  • Ensure accurate geographic data for effective visualization.

  • Leverage interactivity and customization options to enhance user experience.

I hope this guide provides a good starting point for creating and using maps in Power BI. Don't hesitate to ask if you have any further questions or need specific examples!
