Objective
To identify a location in Gombak planning subzone that is suitable for building a National Communicable Disease Quarantine Centre, the following decision factors are studied in this report:
1. Accessibility Factor: The selected site should be close to existing service roads and tracks, to ensure the ease of transportation of resources during the construction of the Centre.
2. Health Risk Factor: The selected site should be away from the population in order to avoid the spread of the disease.
3. Natural Conservation Factor: The selected site should be away from forested land, park and water.
4. Economic Factor: The selected site should avoid steep slope to as it involves a lot of cut-and-fill which would lead to relatively higher development cost.

Features of Interest
Accessibility Factor (Roads)
Service roads and tracks are of concern for our analysis. Hence, they are extracted from OSM roads data. They are concentrated in the north and east areas of Gombak. Overall, road network in Gombak is sparse.
Health Risk Factor (Buildings)
All buildings are treated as population indicators. In general, the Centre should be kept away and isolated from all buildings. Therefore, classifying buildings will not be meaningful for our analysis. It can be observed that the southern area of Gombak is lacking buildings.
Natural Conservation Factor (Natural Features)
There are 1 forest, 4 parks and 3 waterbodies identified.
Economic Factor (Elevation)
The lowest point in Gombak is 8 degrees above sea level, while the highest point is 145 degrees. Natural features are located within the low-lying areas of Gombak while the highest point of elevation can be observed in the southern area of Gombak.
