Land Suitability Analysis to build a national Communicable Disease Quarantine Centre
To identify a suitable location for the construction of a national Communicable Disease Quarantine Centre, there are several criteria to be satisfied. The four concerning factors are as such:
- Economic factor: The selected site cannot be on a steep slope to prevent additional construction costs.
- Accessibility factor: The selected site should be close to service roads and tracks.
- Health risk factor: The selected site should be away from the general populace.
- Natural conservation factor: The selected site should be away from forested land, park and water.
The following map shows the Gombak Planning Area and the factors to be taken into consideration:
Study Area: Gombak Planning Area
View 1 shows the Road Network in Bukit Gombak. For the purpose of the land suitability analysis, we will focus on tracks and service roads which are shown in yellow and purple respectively. View 2 shows the Buildings in Bukit Gombak. View 3 shows the Natural features, which consist of forest (green), parks (pink) and water features (blue). View 4 shows the elevation in Bukit Gombak, where darker areas are of higher grounds and lighter areas are low-lying areas.
Proximity Analysis
View 1 'Road Proximity' shows the proximity analysis of the road network in Bukit Gombak, from a distance of 0 to 702.72 meters. 0 meters, indicated in red, refers to the road itself. As the distance from the road increases, the color spectrum changes from orange to blue, with blue representing areas furthest from the road network and hence the least accessible.
View 2 'Buildings Proximity' shows the proximity analysis of buildings in Bukit Gombak, from a distance of 0 to 827.91 meters. Areas indicated in red are in closest proximity to the buildings while areas indicated in blue are furthest are the buildings, which are the most suitable locations since they are far away from the general populace.
View 3 ' Natural Features Proximity' shows the proximity analysis of natural features including forest, parks and water features in Bukit Gombak, from a distance of 0 to 847.27 meters. Areas indicated in red are nearest to the natural features while areas indicated in blue are furthest away from these natural features. Since the Communicable Disease Quarantine Centre has to be built away from natural features, the areas indicated in blue are the most suitable choice.
View 4 'Slope Proximity' shows the slope map which indicates the level of elevation at different parts of Bukit Gombak. Areas indicated in red are low lying areas below 4.00 meters elevation while areas indicated in blue are of higher grounds of more than 13.45 meters. Since areas with steep slope are not preferred, the areas indicated in red will be most suitable.
