OS Power BI Map Visual

The OS Power BI Map Visual is a custom visual designed to easily display geospatial data on an OS backdrop map in Power BI dashboards. Quickly create insightful maps with a combination of points, lines, polygons or common geographic boundaries provided by the Office for National Statistics.

To get started, download the visual .pbiviz file from Releases and click 'Import a visual from file' in your Power BI software. Visit our documentation for full instructions on how to use the visual.

Features

• Easily create choropleth (fill) or point maps on an OS basemap in Power BI
• Combine points and polygons on the same map to enable greater insights
• Provides easy access to hundreds of commonly used Office for National Statistics (ONS) boundaries such as Lower Super Output Areas (LSOAs) / Middle Layer Super Output Areas (MSOAs) and wards without needing to import your own separate geometry files
• Drag-and-drop geocoding for longitude / latitude, postcodes, Unique Property Reference Numbers (UPRNs) and Eastings / Northings
• Use custom geometries within your map (GeoJSON or WKT) or directly upload shapefiles, geojson or topojson files
• Enable two-way interaction between the map and other visuals (graphs, charts, tables, etc.) within your report
• Highly customisable map formatting and styling options
• Built with security in mind for data protection

Contributing

We welcome contributions from the community via issues and pull requests. The repo is maintained by a team of 2 developers in addition to our normal work but we will try our best to support in a timely manner. Find more details on how to contribute here. We have also documented further information such as our design philosophy, the visual architecture and technical decisions in the repo wiki.

Quick Start to Develop Locally

• To develop this custom visual you will need to have Node.js installed and enable Developer mode in Power BI. You can learn more about how to set up your environment here.
• To get the dev version of the visual up and running, run:
  • npm install
  • pbiviz start
• If the visual doesn't show up, go to localhost (e.g. https://localhost:8080/) -> if it's 'unsafe' click through to continue anyway -> then go to /assets. If you now refresh the visual, it should be visible in Power BI.
• To create a build, run:
  • pbiviz package
