Gombak Subzone Area

The image above shows the 4 different views of Gombak study area.

• 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

Map view with Roads

There are many types of road in Gombak Subzone, I have filtered out the service and track roads for accessibility. Comparing the two types of roads, there are more service type roads than track types roads.

Map view with Buildings

There are different types of building in Gombak subzone. However, majority of the building types are null value hence I did not split based on types as the null types will not value add to any analysis.

Map view with Natural Areas

There are different types of natural areas and I have split them into their types, they are forests, parks and water.

Map view with Digital Elevation

I have splitted the Elevation to 5 classes The steeper the class is the more we should avoid it as the development cost will be higher.

Gombak Subzone Area (Proximity)

Proximity with Roads

I have split the raster into 5 classes in quantile, the nearer the road, the better it is, which also means more accessible. Hence the colour white will be representing a more suitable development decision

Proximity with Buildings

Similarly, the raster has been splitted into 5 classes, the further the building is the better it is for health risk factor.

Proximity with Natural Areas

Similaritly, the raster has been splitted into 5 classes again, the further the natural areas are, the better it is for conservation purpose.
