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. The location must meet the following decision factors:
- Economic factor: The selected site should avoid steep slope. This is because construction at steep slope tends to involve a lot of cut-and-fill and will lend to relatively higher development cost.
- Accessibility factor: The selected site should be close to existing local roads, namely: service roads and tracks. This is to ensure easy transportation of building materials during the construction stage.
- Health risk factor: The selected site should be away from population i.e. housing areas and offices in order to avoid disease spreading to the nearby population.
- Natural conservation factor: The selected site should be away from forested land, park and water.
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. We will get the proximity map of each decision factor layer and give it a criteria or rank. Next, we will rank the importance of the decision factors against each other and use AHP to get the weights for each factor which will be used for raster calculation of our final raster map. Lastly, for land suitability analysis, we will reclassify the table and vectorize the plot of land which suits our needs.
