In-class Exercise 7a: Geospatial Analysis using Tableau

1 Overview

In this exercise, we have some more hands-on using geographical data on Tableau.

We use the realis 2022-2023 data to analyse the property data.

2 Load data

We have 8 realis files and we union them in Tableau.

3 Proportional Map

Note

Note that there are 429 unknown postal codes as they are not available in OpenStreetMap.

We also created a tooltip sheet to show the median unit price for each quarter.

4 Choropleth

We use the Planning Area in the map, hence we need to change it to a geographic role using State.
