Take Home Exercise 2- GIS Modelling for Urban Land Suitability Study


Task: Identify a location suitable for building a national Communicable Disease Quarantine Centre at the selected site of Gombak Planning Subzone


Part 1: Gombak Study Area Map layout with four views

In order to determine whether the location is suitable to build a national Communicable Disease Quarantine Centre, there are a few critical decision factors to take into consideration: Economic, Accessibility, Health Risk and Natural Conservation. Since the selected site is at Gombak Planning Subzone, the following is the map layout that consists of views in relation to the decision factors.

Gombak Study area and the target roads

The target road types are service roads and tracks and the selected site has to be close to the existing local roads. Looking at the first view of the map, we can see that there is high accessibility of service road lines in the North and East side of the Gombak Subzone whereas the other parts of the Gombak does not have local roads to access. To ensure that there is no difficulty in transporting the building materials during the construction stage, the quarantine centre can be built in North eastern area of Gombak.

Gombak Study area and buildings


Health risk factor plays a part when selecting the right location to build the quarantine centre so that it is at far proximity from the buildings that are populated with people. Considering this critical factor, it would be appropriate to build the quarantine centre at the Southern side of Gombak as there is no presence of buildings. The overall presence of the buildings is widely spread out so there are available land for us to select.
