<start_of_turn>model
In Geographic Information Systems (GIS), the union operation plays a critical role in spatial analysis by combining the geometries of two or more geographic features or layers to create new polygons representing their combined areas. Here are some common applications of the union operation in GIS:

Overlay Analysis: Union is often used in overlay operations to find the common areas or intersections between different layers, such as land parcels, administrative boundaries, or environmental zones. This helps in understanding the relationships between different geographic features.

Spatial Data Integration: Union can be used to integrate or merge spatial data from multiple sources. For example, combining land parcel data with census data to analyze population density in specific areas.

Land Use Planning: Urban planners and government agencies use union to identify areas where different zoning regulations overlap. This information is crucial for land use planning and development.

Natural Resource Management: In forestry or environmental studies, union can be used to find the overlap between ecological zones, which helps in conservation and resource management.

Emergency Response: In emergency management, union is used to identify areas affected by multiple hazards (e.g., flood and fire zones) to assess potential risks and plan responses accordingly.<end_of_turn><eos>
