Composite Map
A map created by overlaying multiple spatial data layers, supporting complex spatial analysis
What is a Composite Map?
Multiple thematic layers of spatial data are combined into a single visual representation to create a composite map. Land use, soil type, elevation, climate, vegetation, population density, and infrastructure are a few examples of the data that can be found in these layers. A composite map, created by merging various datasets, provides a more thorough understanding of the region under study, facilitating in-depth spatial analysis and well-informed decision-making.
Urban planning, environmental management, agriculture, and catastrophe risk assessment are among the domains that frequently employ this type of map. For instance, by layering information on slope, rainfall, and soil quality, a composite map may assist in determining the best places for farming. Overlay analysis, data standardization, and visualization with Geographic Information Systems (GIS) software are commonly used steps in the process of making a composite map.

In a GIS, a composite map is made by superimposing many map layers to present merged data in a single view. Through the integration of data from various sources, it facilitates the analysis of spatial relationships, patterns, and trends.
Roads, land use, and satellite images are just a few examples of the several geographical layers that be combined into a single perspective on a composite map. GIS allows you to highlight patterns, modify colours and transparency, and overlay layers for easy visualization and study.
By combining several data layers, composite maps enable geographers to see trends, examine connections, and aid in resource management and planning.
By combining several data layers onto a single map, composite mapping helps make better decisions in fields like resource utilization, environmental management, and urban planning by highlighting links and patterns.
