SMT201 AY2019-20G1 EX2 Eddie Leow Kian Giap

Task

To identify a location suitable for building a national Communicable Disease Quarantine Centre located at Gombak planning subzone with a contiguous area of at least 10,000m2.

Part 1: Gombak and Roads, Buildings, Natural Features and Digital Elevation

A short description of not more than 100 words for each view.

Part 2: Gombak and Proximity to Roads, Buildings, Natural Features and Slope

A short description of not more than 150 words for each view.

Part 3: Criterion Scores of Each Factor Layers

Among all the criteria standardisation techniques, Min-Max technique will be apply to standardize the four raster layers from Part 2 to derive their criterion score.

Let X be the value.
The formula of Min-Max technique is [(X - Min) / (Max - Min)].

Criterion Score for Roads

Formula (in meters): 1 - [(X - 0) / (743.303 - 0)]
The higher the standardized value the nearer it is to the existing service roads and tracks.
The reason why there is a 1 subtracting Min-Max formula is to inverse the standardized value. The existing Min-Max technique will give a standardized value where the higher the standardized value, the further it is to the existing service roads and tracks. However, the decision factor for accessibility is to have the selected site close to existing service roads and tracks.

Criterion Score for Buildings

Formula (in meters): (X - 0) / (838.466 - 0)
The higher the standardized value, the further it is away from the buildings.

Criterion Score for Natural Features

Formula (in meters): (X - 0) / (863.669 - 0)
The higher the standardized value, the further it is away from forested land, park and water.

Criterion Score for Slope

Formula (in degrees): 1 - [(X - 0) / (36.419 - 0)]
The higher the standardized value, the lower the degree of the slope.
The reason why there is a 1 subtracting Min-Max formula is to inverse the standardized value. The existing Min-Max technique will give a standardized value where the higher the standardized value, the higher the degree of the slope. However, the decision factor for economic is the selected site should avoid steep slope.
