When performing a point-in-polygon overlay, the result is a new point layer where each point located within a polygon is associated with the attributes of that polygon. This process essentially combines the spatial relationship of points inside polygons with the respective attributes of those polygons, allowing for rich attribute data to be linked to the points based on their location.

This functionality is critical in many GIS applications, where understanding how points relate to geographical features represented by polygons can inform analysis and decision-making. By creating a new point layer in this manner, the analysis can reveal trends, spatial distributions, or anomalies corresponding to the attributes of the polygons—such as zoning regulations, land use types, or demographic data.

The other potential outcomes, such as creating a line layer, producing distinct point features without attributes, or summarizing points into a polygon layer, do not accurately reflect the primary goal of a point-in-polygon overlay, which emphasizes the enrichment of point data with polygon attributes rather than transforming or summarizing information differently.
