Part 1 : Thematic maps

Distribution of public education institution

Different symbols were used for the different public institutes. The institutes that are using the same symbols are distinguish by the different colour and size. This is so that users can have a clearer visualisation of the different public institutions.

Hierarchy of road network system of Singapore

A new column “category” was added to the dataset to classify the different roads types (e.g. Expressway, major, minor and unknown roads etc.). Different colours and different thickness of the line symbols represents the different type of roads(e.g. expressways are thicker compared to the other roads) This helps user to have have an easier and clearer visualization of Singapore's road network.

2014 Master Plan Landuse

In the 2014 Master Plan, some of the landuse were categorised together. Example will be the business sector(Business1, Business2 etc.). Reason for merging some of the sectors is to reduce the number of colours shown on the map so that the different Landuse are easier to visualize.

Part 2 : Choropleth maps

Aged population (+65) in 2010 and 2018

Special patterns: There seems to be a higher aged population in the East side of Singapore.

Explanation: Graduated symbol is used, age0-age64 being in pale blue. The older a person gets, the darker the shade of blue.

Proportional of aged population in 2010 and 2018

Special Patterns: Similar to 2010, the aged population was also higher in the East side of Singapore during 2018.

Explanation: Similar to 2010, I also used the Graduated symbol to map the proportional aged population. In addition, quantile mode was used.
