When you have two sources of spatial data – such as Airbnb locations and EV charging point locations – and you want to analyse the spatial relationships between them, such as determine how many Airbnbs are within a certain distance from an EV charging point, Tableau’s spatial functions can be extremely useful.
In this video, I walk through the above scenario and show:
- How to connect to multiple sources of data
- How to perform high-level visual analysis using map layers
- How to create a spatial join between two data sources
- How to use MAKEPOINT(), BUFFER() and DISTANCE() spatial functions
- How to make your spatial analysis dynamic with the help of parameters
