The digital elevation is used to assess the economic factor.

The lowest elevation of 10 meters above sea level is mostly located at the north side of Gombak and the area with highest elevation of 143 meters above sea level is mostly located at south side of Gombak. Building site at area with highest elevation will inevitably generate more cost, therefore, the financial capability of the company that is paying for the construction of the quarantine centre.

The objective of this analysis is to identify a suitable location for building a National Communicable Quarantine Centre in Gombak planning subzone. This location need to have a contiguous area of at least 10,000m2 and its analyzed based on the following factors:

  • Economic factor
  • Accessibility factor
  • Health risk factor
  • Natural conservation factor

Buildings

The building footprint is used to assess the health risk factor. The selected site should not be near populated area in order to prevent the spread of diseases when the quarantine centre is eventually built. The buildings is not categorized in the map as the buildings was not categorized well, with majority of the buildings labelled as "Unknown" in the data obtained from BBBike, and therefore, categorizing the buildings will not be useful in this case.

Natural Features

The natural features is used to assess the natural conservation factor. The selected site should be away from these natural features, particularly away from waterbody as the water can be contaminated easily. In this case, the natural features located in Gombak is categorized into three categories, namely forest, park and waterbody. The location of these natural features is scattered around south-west, north and east side of Gombak.

Roads

The roads, specifically track(thinner line) and service(thicker line), is used to assess the accessibility factor. The selected site should be close to these roads so as to facilitate transportation of materials during the construction stage. From the map, you can see that the two types of roads is mostly scattered across Gombak, indicating that multiple areas we have to select the site.

Digtial Elevation

The digital elevation is used to assess the economic factor. The selected site should avoid steep slopes as building a quarantine on a steep slope will incur more development cost for the construction of the quarantine centre. The lowest elevation of 10 meters above sea level is mostly located at the north side of Gombak and the area with highest elevation of 143 meters above sea level is mostly located at south side of Gombak. Building site at area with highest elevation will inevitably generate more cost, therefore, the financial capability of the company that is paying for the construction of the quarantine centre.
