Part 1: Map Layouts of Extractions
Target Roads
There is a higher number of target road networks in the central and eastern part of the Gombak study area. To build the quarantine centre, it is suitable to build at these areas due to the transportation of the materials for the construction of the quarantine centre.
Buildings
By using Master Plan 2014 Land Use and OSM’s buildings layer, I intersect them and classify them according to the building types. Residential buildings are saturated in the western side and northern side of the study area. Furthermore, military buildings (i.e. Bukit Panjang Camp) are at the central of the study area. In addition, train stations are at the eastern side of the study area. Hence, it is ideal to set up the quarantine centre at the southern side of the study area to stay away from those stated buildings.
Target Natural Features
According to the three types of nature features namely forest, parks, and water, the proposed quarantine centre needs to stay away from these nature features. Hence, it is ideal to set up the quarantine centre at the southern side of the study area.
Digital Elevation
The colours of the elevation are represented where green means flat land, orange-yellow means mid-level land, and red means high-level land. To fulfill the economic factor of building at gentle slope, it is suitable to build the quarantine centre at the green areas of the slope according to the raster.

Part 4: Analytical Hierarchical Process (AHP)
Before computing AHP and to find out the suitability of building Communicable Disease Quarantine Centre, we have to decide criteria relevant to our goal which I have identified and arranged in the hierarchy illustrated in the above figure. This allows the incorporation and accommodation of both qualitative and quantitative criteria for assessing the suitability of building Communicable Disease Quarantine Centre. So, let’s start computing AHP.
Part 5: Suitability Analysis
Based on the weights computed in AHP (which are equal to 1), we use Raster Calculator to calculate the suitability by applying the following formulas:
