PART I: Thematic Mapping
Map 1: Distribution of Public Education Institutions in Singapore
Description
For this map, the data points were further classified and designed according to their type or main level, namely Centralised Institute, Mixed Level School, Junior College, Secondary School and Primary School, allowing the map viewer to differentiate the different public education institutions around Singapore.
The 2014 Planning Subzone Regions were also used to signify the regions of Singapore, allowing the viewer to further view these institutions in their appropriate regions. The OpenStreetMap layer was inserted to further pinpoint the location of the institutions in terms of different transport modes that can be taken to reach them, nearby amenities etc.
Map 2: Road Network System of Singapore
Description
The data points were further classified and designed according to their type and symbol description, namely Expressway, Expressway-Sliproad and Major Roads. Contour lines were removed due to its inapplicability and the international boundary was replaced using the OpenStreetMap layer that also represents this. The expressways were labelled accordingly to their name, allowing the map viewer to view these expressways at a glance.
With the function of Rule-based labelling, the major roads were also labelled accordingly with a minimum scale of 1:100000, allowing the viewer to zoom in and identify these roads which can be connected to the expressways via sliproads.
Map 3: 2014 Master Plan Landuse
Description
The areas were narrowed down to the following which I feel are relevant in this map. The OpenStreetMap layer was also added for the map viewer to easily identify these areas.
With the land scarcity of Singapore, this map was designed to emphasise the open spaces of Singapore that could be utilised for further developments. The special/reserved areas designate the areas which are unavailable to be utilised. With Singapore being a major transhipment hub relying on exports from foreign countries, waterbodies and agriculture are also highlighted in this map where these areas could be substituted for other purposes.
PART II: Choropleth Mapping
Background Information
For the following maps, the term ‘Aged Population’ refers to Singaporean residents who are at least 65 years of age.
The 2014 Planning Subzone GIS data and the 2008 Planning Subzone GIS data by the Urban Redevelopment Authority were utilized for the maps portraying the related population in 2010 and 2018 respectively. This is to cater for the difference in the subzone areas between 2014 and 2008, in which the subzones that are present in the 2014 Planning Subzone GIS Data might not be present in the 2008 Planning Subzone GIS data, leading to data discrepancies and unaccounted values.
For instance:
2008 Planning Subzone GIS data: Subzone_Code AMSZ08 is YIO CHU KANG
2014 Planning Subzone GIS data: Subzone_Code AMSZ08 is TAGORE. YIO CHU KANG is AMSZ10 instead.
