Gombak Maps

Gombak Roads

The criteria for the quarantine site selection involved studying the proximity to service roads & tracks for ease of construction. These 2 road types were identified and filtered for further study.

These roads are well spread out across the whole Gombak subzone.

Gombak Buildings

On comparing the buildings with the addresses & street view on Google maps, I realised a vast majority of the buildings were either residential, commercial-based or have high throughput of individuals on a regular basis, such as places of worship or childcare centres). The quarantine centre's proximity to these areas also carry a high risk to the population, hence I decided to include all buildings into my analysis.

The buildings generally occupy the western, northern & central areas of Gombak, with very few of them in the south & southeast.


Gombak Natural Featues

3 kinds of natural features exist in Gombak -- Forests, parks & water bodies -- which are all distinctly shown on the map.

These areas are located near the eastern, northwestern & southwestern periphery of the subzone. The southwestern regions of Gombak are devoid of such natural features.


Gombak Elevation

Gombak's highest areas lie in its southern region (blue & green); the elevation decreases radially from there and gentles into low elevations nearer to the other edges of the subzone (orange & red).
