GIS Modelling for Urban Land Suitability Study
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.
The Data
Three major data sets will be used in this hands-on exercise. They are:
- Master Plan 2014 Subzone Boundary from URA. This data can be downloaded from data.gov.sg.
- Roads, buildings and natural features data from OpenStreetMap (OSM) data sets. These data can be downloaded from BBBike@Singapore.
- ASTER Global Digital Elevation Model (GDEM) dataset jointly prepared by NASA and METI, Japan. This data can be downloaded from NASA’s EarthData Search site.
The GDEM data set is already provided in the hands-on exercise data folder. Both Mater Plan 2014 and the OSM data sets, on the other hand, need to be downloaded from their respective sources provided above.
The AHP
Although SAGA provides Analytical Hierarchical Process function. But the function does not provide detail report. In view of this, students are encouraged to use Excel-based AHP library such as the AHP Template provided by SCB Associates
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.
Due Date: 10th November 2019, 11:59PM (mid-night)
Need Help!
If you need help and you think that your question might be of interest to the whole class, send the question to Discussion Forum. If you would prefer to ask just the class staff, send an e-mail to me. Regardless, please don't be shy about asking for help if you are struggling with understanding the assignment or having trouble with a particular aspect of QGIS. I have heard stories of students struggling for many hours over minor issues that had easy solutions. I would like you to avoid these misadventures, so please contact me sooner rather than later if you get stuck.
