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
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.
| 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. |

2.Map Layout of Study Area with Proximity
| Proximity to target roads |
 |
| Proximity to buildings |
 |
| Proximity to target natural features |
 |
| Proximity to slope |
 |
3.Map Layout of Study Area with Ranked Proximity
| Ranked Proximity to target roads |
 |
| Ranked Proximity to buildings |
 |
| Ranked Proximity to target natural features |
 |
| Ranked Proximity to slope |

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:
