Take Home Exercise 2

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

1.Map Layout of Study Area

Composite map

Composite map.jpg

This is the composite map of Gombak planning subzone which contains the building layer, natural features layer which consists of both Waterway and Natural layers combined through Union and the road layer. This map will be the base map of our further analysis.

Template:Center top

Gombak roads

This map layout shows the planning subzone with the available roads, attained by clipping the road layer from OSM and the planning subzone layer together with the road layer being the input layer and the subzone layer the clip layer.

Gombak buildings

This map layout shows the planning subzone with the buildings contained in it, attained by clipping both layers with the building layer being the input layer and the subzone layer the clip layer.

4.Analytical Hierarchical Process

Using Excel-based AHP library such as the AHP Template provided by SCB Associates, the 4 criterias which are Economic factor (slope), Accessibility factor (road), Health risk factor (building) and Natural conservation factor are inputted and ranked according to importance of factor against each other. Using the scale provided, I have given the values as such:
