Buildings: To build a disease centre, it needs to be far away from the population to prevent spreading of diseases to the nearby population. The data was extracted from BBBike@Singapore. As Singapore is highly compact, once the disease hits a population, it can easily spread and is important to keep the disease centre away from nearby population.

Target Roads: To build a disease centre, it needs to be close to existing local roads, namely: service roads and tracks to ensure easy transportation of building materials during the construction stage. The data was extracted from BBBike@Singapore. The targeted roads had to be extracted by 'select features using an expression' to extract the service roads and tracks from the 'type' column.

Natural Conservation: The selected site needs to be away from forested land, park and water as when the disease enter the water bodies of Singapore. The data was extracted from BBBike@Singapore.

Elevation: The selected site needs to avoid slope as this will incur large construction cost as steep slopes involves a lot of cut-and-fills and leads to relatively higher development costs. The data was extracted from NASA's EarthData Search Site and was prepared by importing the raster data into QGIS. The higher the value, the higher the elevation of the location , measured in degrees.
