PART 1 THEMATIC MAP

The map above shows the distribution of public education institutions in Singapore. For this thematic map, I used the categorize function to classify different schools with the feature "main level_". Since the data points of the school are nominal in nature I have a few options, namely, the use of shape symbols or varying hues. In this particular case, I have tried out both the options and I realized that using different hues can help the viewer distinguish the schools better than symbols. Hence, I chose hues to represent the various schools in Singapore.

=== The map above shows the different hierarchies of roads in Singapore. They are namely Expressway, Major Arterial, Local Access, and Minor Arterial. I classified the hierarchy of roads based on LTA's official documentation. A new field is added and used to classify the roads based on keywords such as Expressways, Highways, Drive, Avenue etc. I then categorize them based on this new field and adjusted the width of roads as well as colors to help distinguish the hierarchy of roads. ===

For the Master Plan Landuse 2014 thematic map, I used LU_DESC which is already in the dataset to classify the various landuse functions. Various hues are then used to distinguish the land use of each sub-zone within Singapore. Due to the number of types of landuse functions, I have decided that using symbols for every type of use could look disorganized. Therefore, I chose to use hues to represent each land use function. However, if the purpose is to visually identify a single landuse function such as residential land use in Singapore amongst the various landuse function, a better way may be to use symbols to distinguish them. ===
