Expand the detected arplane based on player's real world position

Is it possible to make this work? I detect lets say a small arPlane on the ground and start placing objects. Then what i'd like to do is: as i move around, the detected plane expand underneath me without me having to scan the ground all the way to where i moved to. for example, i start my app and im at point 'A', i scan the ground which generates arPlane on the ground that i scanned. Now i move to point 'B' say a meter or two away from point A, the app without me scanning the ground again, updates the already detected plane such that the path i took from A to B is now part of the original generated plane. possible?
