GIS Modelling for Urban Land Suitability Study

We are conducting a study to identify a suitable location for building a National Communicable Disease Quarantine Centre located at Gombak planning subzone. The site would need to have a contiguous area of at least 10,000m2 and meet the following criteria:

1) Economic factor: The site should avoid having steep slopes as that would require cutting and filling which would amount to a relatively higher development cost.
2) Accessibility factor: The site should be close to existing roads (service roads and tracks) for easy transportation of building materials
3) Health risk factor: The site should be away from the population as we would want to prevent the disease from spreading.
4) Natural conservation factor: The site should be away from forested land, water and parks.

Part 1: Map View with Study Area, Target Roads, Buildings, Natural Features, Digital Elevation

The data for this analysis was obtained from the Master Plan 2014 Subzone Boundary, BBBike Singapore (buildings, roads, nature) and ASTER Global Digital Elevation Model (Elevation raster layer).
