Part 1 : Map View with Study Area and Target Roads, Buildings, Natural Features, Digital Elevations Layer

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.
