Chapter 18. Advanced Mapping
In Chapter 6, we covered basic mapping functionality within Tableau. This chapter covers the more advanced mapping techniques and functionality that you can do within Tableau. These advanced mapping techniques came into Tableau from 2018 onward and made an impression on how you can advance your mapping capabilities.
Always map responsibly and make sure you are taking into consideration proportionality (not creating a map that misrepresents the data).
This chapter uses United States mainland flights data to enable full use of the mapping capabilities.
Note
Tableau has some mapping capabilities built in—for example, the ability to select a state or city as a geographic field. To use the advanced mapping functionality, you will need to have a dedicated latitude and longitude field to use within spatial calculations.
