Part 1: Thematic Mapping

Distribution of Public Education Institution by School Types

The point symbols I used in the Education layer represent each school and its location. Each school is a zero-dimensional feature on the map. This is done such that users can easily observe the spread of education institutions in each planning area. The educational institutes are discrete quantitative values that exist on a single location on the map. Each type of educational institute (ie. Centralised Institutes, Junior Colleges, Secondary, Primary) is represented by a different symbol of different colour so that it is easier to differentiate between them.

Road Network System Hierarchy of Singapore

I used a single colour for the RoadSection Line and colour saturation. The line symbols represent the various major and minor roads and expressways in Singapore, which are qualitative values. Line symbols are also one-dimensional as they indicate the flow of roads in the country. A new column “RD_TYPE” was added to the dataset to classify the dataset into different types of roads. Each type of road is represented by a different coloured line of different width to differentiate between them.
