Overlay Maps of Landscape Resource Attributes for Selayang-Rawang Region, Selangor (using MapInfo)

GIS software platforms like ArcGIS, QGIS, MapInfo and others provide tools and functionalities for
performing composite map overlay operations and creating visually informative composite maps. These
techniques are valuable for gaining insights into geographic data and facilitating data-driven decision-
making processes in various industries and applications. As mentioned, the layering technique is
performed based on the assigned attributes. For example, Figure 2 below shows the attribute set of
topography, soil and geology, as well as attribute set of hydrology for Selayang-Rawang region. Each
attribute set has a few parameters on individual layer maps such as slope gradient, slope types, density of
development and groundcover, natural waterbodies, drainage system, as well as flood risk area. The colour
hue intensity depicts the scoring or rating criteria for the attributes – e.g.: the darkest hue represents the
lowest suitability, and the brightest hue represents the highest suitability of land usage or development
potentials.
