Which spatial selection method allows a user to select polygons that share at least half of their area with another large polygon?

The spatial selection method that allows a user to select polygons sharing at least half of their area with another larger polygon is through intersection. While the provided answer is incorrect, the most appropriate choice would involve the concept of area overlap or spatial relation rather than identical attributes.

Intersecting the source layer feature means that polygons that share any geometric overlap with the selected feature will be included in the selection. This method effectively captures all polygons that either partially or fully overlap with the specified area, aligning with the requirement of including those that share at least half of their area.

When comparing other means of selection:

• Touching the boundary would only select polygons that share a border with the source polygon, not necessarily based on a percentage of overlapping area.

• Being identical to the source layer feature would select only those polygons that completely match the geometry of the source polygon, which is too restrictive for the criteria of area sharing.

• Selecting based on the centroid being within the source layer feature might imply proximity but does not satisfy the condition of area overlap, which is crucial for the requirement posed in the question.

Thus, for the task of selecting polygons based on shared area, intersection is the most relevant method, ensuring that all polygons which significantly share space with the larger polygon are accurately identified
