Adding data to the map

The following pages cover adding data to the OS basemap in the OS Power BI Map Visual.

Core concepts

The visual allows you to add up to three layers to the map at once, which can be styled and symbolised separately. There is a marker points layer, a features layer, and a reference layer.

The marker points layer can contain point-based data from your Power BI data model, which can be supplied either as coordinates, postcodes, or Unique Property Reference Numbers (UPRNs).

The features layer can contain point, line, or polygon data which can be supplied in one of three ways: directly from your data model as WKT or GeoJSON; geocoded from Government Statistical Service (GSS) codes in your data model; or matched from a column in your data to features in a spatial dataset that you can upload into the visual.

Finally the reference layer can contain reference data such as administrative boundaries which are geocoded from GSS codes but are not matched to any specific data from your data model.

Creating and styling map layers

The pages below include detailed guides on creating and styling a point map within the visual:
