Part 1: Thematic Mapping
Distribution of public education institution by school types
Using the Pin Map to map out the distribution of public education will allow us to see the discrete data points on the map more vividly. By changing the Symbol Layer, employing relevant SVG marker to indicate different level of the educational institution, and giving different sizes to the different level of the educational institution, we will be able to identify the necessary school better.
Hierarchy of Road network system of Singapore
I have used the RoadSectionLine_Apr2019 data from LTA DataMall and I figure that using the column expression of the Symbology function allows me to perform categorization better. I made my reference to https://remembersingapore.org/2018/08/15/singapore-street-suffixes/ when I was categorizing the 3 different levels of road type. By assigning the expressway to a higher stroke width followed by major roads then the minor roads, I think it is easier for readers to identify the major landscape.
2014 Master Plan Landuse
Similar to the technique I use in the Hierarchy of Road network system of Singapore, I use the column expression function to classify the different land usage to their rightful functional group. By using https://en.wikipedia.org/wiki/List_of_building_types as my reference, I have randomized the color ramp to show the difference in the proportion of land use in Singapore. As we can see in the map, most of Singapore’s land use is for residential purposes.
