Intersect

The Intersect operation is a fundamental GIS analysis tool used to combine two or more spatial datasets and identify only the geographic areas where they overlap. The resulting output layer contains the shared features from all input layers while retaining the attribute information from each dataset. This enables users to analyze both spatial relationships and associated data within a single layer. Intersect is widely used for location-based decision-making across industries. For example, it can identify land parcels within flood-risk zones, determine wildlife habitats that overlap with protected areas, assess infrastructure located inside administrative boundaries, or analyze development sites affected by environmental constraints. It is also valuable in urban planning, environmental monitoring, disaster management, transportation planning, and natural resource management. By merging spatial and attribute data into one comprehensive dataset, the Intersect operation simplifies complex analyses, improves mapping accuracy, and supports informed, data-driven geospatial decisions.
