Options are available to union buffers and to use geodesic distance. A numeric field. bufferSR. Syntax: constrain( , , ). Hot Network Questions Can one planet in our system eclipse another one? There are two basic methods for constructing buffers: Euclidean and geodesic. Buffered features are created as line or polygon features using the settings of the chosen feature template.
