Part One - Map Views w Roads, Buildings, Natural Areas and Elevation

Map with Roads

After exracting the Gomback area out, we put the road layer on top. For Road layer, we specificly focus on Servie Roads and Tracks. Since the Disease Quarantine Centre requires a better accessibility factor, so the suitable slot should locate closer to the roads. I used red color to represent track and blue color to represent service roads, so that viewr can better differenciate those two types of roads.
By looking the map view alone, suitable slots should locate at north-east area.

Map with Buildings

I used blue color to represent building areas, as we can see from the map view above, most of the buildings are locate at northern part or sorth-west areas. Since we need to consider the health risk factor, and we need to put the suitable slots far away from populations, in this case, the building areas, thus, based on the building map itself, the suitable slots should be located at southern Gombak area.

Map with Naturals

For the naturals map view, I used different color to represent different type of natural areas. I used green to represent forest, pink for park and baby blue for water. For natural conservation factor, we need to put the suitable slot far away from the natural areas, based on the naturals map alone, the slots should be put around southern Gombak area.

Map with Elevation

As you can see from the Elevation map, I used different color to represent areas with different elevation, yellow areas have higher elevation while the dark areas have lower elevation, green areas have relatively middle elevation.
As you can see, the middle Gombak area is the most elevated, we shoudl consider avoid putting suitable slots here.

Part Two Proximity Raster w Roads, Buildings, Natural Areas and Slope Raster layer

Roads Proximity Map

Min = 0 meters, Max = 742.560163330078 meters As you can see from the Roads proximity map view, I used dark red color to represent the rastered roads. I used red colors to represent those areas who are closer to roads and I used cold color like blue to represent areas who are far from roads, since the Quarantine Centre should be located close to the roads, the red areas could be the potential slots.

Buildings Proximity Map

Min = 0 meters, Max = 837.627415466309 meters I used redish color to represent areas which close to the buildings to alarm viewers, becasue those are the areas close to population which are the areas we need to avoid when we choose suitable slots. The areas with cold color like blue, are areas far from population and could be the potential suitable slots.

Naturals Proximity Map

Min = 0 meters, Max = 862.805825134277 meters I use redish color for areas closer to naturals and darker and colder color for areas which far from the naturals

Slope Raster Map

Min = 0 degrees, Max = 36.3826292610168 degrees I used blue color to represent those areas who has steep slope and yellow color to represent areas which are more flat.
