These are just some of the issues with doing spatial analytics in a business intelligence tool: Have you ever had to deal with the EPSG projection in data before? Welcome to geospatial analytics. You can see the problems illustrated in videos like this one and this one. This presents a number of issues when trying to move geospatial data into Tableau.

In short geospatial data has added complexity compared to non-geospatial data and tools like Tableau and Power BI are built primarily for tabular data that is not geospatial in nature. Want to add a few more layers like points or demographic data to your map? You likely won’t be able to as there are data layer limits in both tools. While there are a few common data types like Shapefiles and GeoJSON there are close to 200 individual formats of geospatial data. If you need to translate data formats.Either large number of rows or features or complex geometries (take a look at the coast of Norway if you need an example). Using custom geospatial data or anything that goes beyond commonly used boundaries like states (for example latitude and longitude points would fall into this category.If you want to go beyond a map of states or provinces you certainly can but you are likely to hit roadblocks if you are: However… Spatial data wasn’t made for Power BI or Tableau You can quickly see your data in a location context and learn something about the spatial arrangement of your data alongside your other data. Theĭarker colors indicate locations with more pickups, and the lighter colors indicate locations with fewer pickups.For simple data visualizations like this BI tools provide a great interface.

The marks update on the map to show the concentration of taxi pickups per location.

On the Marks card, click the Mark Type drop-down and select Density.

Drag a measure field, such as ID, to Detail on the Marks card.

Note: Because Tableau is averaging the latitude and longitude of the data, there is only one mark on the canvas.

From the Data pane, drag both Pickup Latitude and Pickup Longitude onto the canvas.

To learn more about Heatmaps and find out how to create and customize them, see Create Heatmaps that Show Trends or Density in Tableau. Heatmaps are most effective when working with a data set containing many data points where there is substantial overlap between the marks on the map. Heatmaps, also known as Density Maps, help you identify locations with greater or fewer numbers of data points. The polygons on the map update to show the amount of sales using color. The map view updates to a filled (polygon) map.įrom the Orders table in the Data pane, drag Sales to Color on the Marks card. On the Marks card, click the Mark Type drop-down and select Map. The background map updates with the new settings. Under Background Map Layers, clear Country/Region Names.In the Background pane, click the Style drop-down and select Normal. The data points on the map update to show the amount of sales proportionally. To learn more about geographic fields and how to create them, see Assign a geographic role to a field.įrom the Orders table in the Data pane, drag Sales to Size on the Marks card. In the Data pane, open the Location folder and double-click State.Ī map view is automatically created because the State field is a geographic field. To follow along with the example below, open Tableau Desktop and connect to the Sample-Superstore data source, which comes with Tableau.

This topic illustrates how to create a simple map using an example. If your data source doesn't contain location data, see the Map Data (Link opens in a new window) section for ways you can connect to location data. Prerequisites: To build a simple map, your data source must contain location data (for example, location names or latitude and longitude coordinates). If you're new to maps, or simply want to take advantage of the built in mapping capabilities that Tableau provides, you can create a simple point or filled (polygon) map similar to the examples below. You can build several different types of maps for your geographic analysis in Tableau.
