When your query\nresults contain one or more `GEOGRAPHY` type columns, you can view the results\nin an interactive map.\nTo view the map, in the **Query results** pane, click the **Visualization** tab.\n\nVisualization in BigQuery is ideal for quick inspections and\niterative query development. You can visually confirm data alignment with\nexpectations, identify outliers, and assess the correctness of your spatial\ndata. It's also useful for ad hoc analysis to explore results and derive\nimmediate conclusions from geospatial queries.\n\nTo see an example of how to use the integrated geography viewer, see\n[Get started with geospatial analytics](/bigquery/docs/geospatial-get-started).\n\n### BigQuery Studio limitations\n\n- You can only visualize one `GEOGRAPHY` column at a time.\n- Performance is subject to browser capabilities and isn't intended for rendering extremely large or complex datasets. BigQuery renders up to approximately one million vertices, 20,000 rows, or 128 MB of results.\n\nLooker Studio\n-------------\n\nLooker Studio is a no-cost, self-serve reporting and data visualization\nservice from Google Marketing Platform that connects to BigQuery\nand hundreds of other data sources. The service includes support for a variety\nof [geographic field types](https://support.google.com/looker-studio/answer/9843174)\nand [choropleth maps](https://en.wikipedia.org/wiki/Choropleth_map) of\nBigQuery `GEOGRAPHY` polygons. With\n[Google Maps-based visualization](https://support.google.com/looker-studio/answer/9713352),\nyou can visualize and interact with your geographic data just as you do with\nGoogle Maps: pan around, zoom in, and pop into Street View.\n\nFor a walkthrough of geospatial analytics in Looker Studio, see\n[Visualize BigQuery `GEOGRAPHY` polygons with Looker Studio](https://support.google.com/looker-studio/answer/10502383).\n\nBigQuery Geo Viz\n----------------\n\nBigQuery Geo Viz is a web tool for visualization of geospatial\ndata in BigQuery using Google Maps APIs. You can run a SQL query\nand display the results on an interactive map. Flexible styling features let\nyou analyze and explore your data.\n\nBigQuery Geo Viz is not a fully featured geospatial analytics\nvisualization tool. Geo Viz is a lightweight way to visualize the results of a\ngeospatial analytics query on a map, one query at a time.\n\nTo see an example of using Geo Viz to visualize geospatial data, see\n[Get started with geospatial analytics](/bigquery/docs/geospatial-get-started).\n\nTo explore Geo Viz, go to the Geo Viz web tool:\n\n[Go to Geo Viz](https://bigquerygeoviz.appspot.com/)\n\n### Geo Viz limitations\n\n- Geo Viz supports geometry inputs (points, lines, and polygons) that are retrieved as a `GEOGRAPHY` column. You can use BigQuery's geography functions to convert latitude and longitude to `GEOGRAPHY`.\n- The number of results that Geo Viz can display on a map is limited by browser memory. You can lower the resolution and reduce size of geospatial data returned from the query by using `ST_Simplify` function.\n- Real-time, interactive analysis is handled locally by your browser and is subject to your browser's capabilities.\n- Geo Viz supports sharing visualizations only with users authorized to execute queries in the same BigQuery project.\n- Geo Viz does not support downloading a visualization for offline editing.\n\nColab notebooks\n---------------\n\nYou can also perform geospatial visualizations in Colab\nnotebooks. For a tutorial on building a Colab notebook to\nvisualize data, see [BigQuery geospatial visualization in Colab](/bigquery/docs/geospatial-visualize-colab).\n\nTo view and run a prebuilt notebook, see [BigQuery geospatial visualization in Colab](https://github.com/GoogleCloudPlatform/bigquery-utils/blob/master/notebooks/bigquery_geospatial_visualization.ipynb) in GitHub.\n\nGoogle Earth Engine\n-------------------\n\nYou can also visualize geospatial data using Google Earth Engine. To use\nGoogle Earth Engine, export your BigQuery data to Cloud Storage\nand then import it into Google Earth Engine. You can use the Google Earth Engine tools\nto visualize your data.\n\nFor more information on using Google Earth Engine, see the:\n\n- [Google Earth Engine developer's guide](https://developers.google.com/earth-engine/)\n- [Google Earth Engine API tutorials](https://developers.google.com/earth-engine/tutorials)"]]
