WebThe Buffer operator creates a buffer polygon around the input geometry at a specified distance. If the input geometry is a polygon and a negative distance is specified, then the buffer polygon could be inside the input geometry. The specified distance is in the units of the associated spatial reference. WebSummary. Creates polygons that cover a given distance from a point, line, or polygon feature.

The fundamental method to create a buffer around a geographic feature stored in a vector data model, with a given radius r is as follows: • Single point: Create a circle around the point with radius r. • Polyline, which consists of an ordered list of points (vertices) connected by straight lines. This is also used for the boundary of a polygon.
