Our team's objective is to analyse and determine how these facilities such as transportation, school and healthcare services would impact the accessibility level around HDB.
Social inequality has been the hot topic in recent years as government start to find sustainable ways to tackle the increasing inequality and stratification in Singapore.However, with constant development and improving infrastructure around Singapore, the impact on accessibility has not really been research upon.

User Interface Prototype
Tools and Data Architecture
- 1. Most of the datasets retrieved provided only addresses, not coordinates. Thus, first we had to geocode each point to get the coordinates.
- 2. Some datasets had CRS WGS84 while some had SVY21. Thus, we had to convert all to SVY21
- 3. Calculating the distance from each of the 8500 houses to each of the 5000 bus stops was computationally impossible. Thus, we had to use Raster to create a radius around each house and calculate distance from that house to the bus stops which lay within the radius to get the closest bus stop
- 4. Plotting 8000 points on a map was very cluttered and not insightful. Thus, we provided the user options to select regions/subzones/towns for better plots
