Overall, overlay mapping techniques are essential tools in GIS for conducting suitability analysis
and making informed decisions in various domains such as land use planning, flood management, and
agriculture. These techniques involve combining and transforming geographical data to generate
suitability maps based on multiple criteria and weights. They play a central role in many GIS applications
and are widely used in spatial planning and decision-making processes. These approaches, supported by
innovative tools and methodologies, can help identify suitable areas for conservation, assess potential
impacts, and develop adaptation strategies. Coordinated efforts across different sectors and the active
involvement of local residents are crucial for effective landscape management and the preservation of
heritage resources.

Results and Discussion

Application of Overlay Mapping and Suitability Analysis

The overlay mapping technique is anticipated to reveal the precise locations of natural and cultural
heritage sites in relation to the broader landscape. This includes the identification of historical
monuments, archaeological sites, and culturally significant natural features. The suitability analysis is
expected to generate maps indicating optimal areas for land resource planning while safeguarding cultural
heritage. These maps will highlight zones where development aligns with heritage preservation goals and
where caution is needed to prevent cultural erosion. Based on Figure 1, various environmental, physical
and social attributes for Selayang-Rawang region in Selangor have been mapped in individual map layer
such as microclimate, topography, landuse, heritage and socio-economic as well as circulation and
accessibility. The maps were created with different colour coding to differentiate the representation of
landscape resource attributes and they were shaded with colour hues to indicate the suitability analysis
scoring. All the maps were layered to obtain the final scoring and composite map.
