SMT201 AY2019-20G1 EX2 Linus Cheng Xin Wei

The Task

In this exercise, you are tasked to identify a location suitable for building a national Communicable Disease Quarantine Centre. The selected site must be located at Gombak planning subzone, with a contiguous area of at least 10,000m2 and it 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.

Submission Details

This is an individual exercise. You are required to work on the take home exercise and prepare submission individually.

Project artefact: All geospatial information compiled and derived, including the QGIS project file and data dictionary. The geospatial and aspatial data must be stored in a single GeoPackage. The project artefact must be uploaded onto eLearn.

Take-home Exercise Report: You are required to edit your take home exercise in the appropriate wiki page of the Take-home Exercise Dropbox. The take home exercise report, beside others, should include all the thematic and choropleth maps prepared and their respective discussion. The title of the wiki page should be in the form of: SMT201_AY2019-20G1_Ex2_FullName.

The report must provide the followings:

• A map layout with four views showing:
  • the study area and the target roads,
  • the study area and buildings,
  • the study area and the target natural features,
  • the study area and digital elevation, and
  • a short description of not more than 100 words for each view.
• A map layout with four views showing:
  • the study area and proximity to target roads layer,
  • the study area and proximity to buildings layer,
  • the study area and proximity to target natural features layer,
  • the study area and slope layer, and
  • a short description of not more than 150 words for each view.
• A map layout with four views showing the criterion scores of each factor layers and a short description of not more than 150 words for each view.
• An Analytical Hierarchical Process input matrix and result report and a short description of not more than 150 words discussing the analysis results.
• A map layout with the suitability land lot(s) and a short description of not more than 200 words commenting on each of the suitable land lot identified.

Overview Map

Map View w Roads

Although there are many types of roads found in the Gombak Subzone, I have filtered and charted the map based on the two target road types for accessibility, service & track. We can see from 1. that we have more service type roads as compared to track type roads, as well as a rather sparse road network that does not cover the whole Gombak area.
