1. A three-dimensional data encoding method of encoding geometry information of a first three-dimensional point cloud located in a first area, the three-dimensional data encoding method comprising:
selecting a moving method from among a plurality of moving methods;
determining a second area based on the moving method selected and the first area;
moving a second three-dimensional point cloud located in the second area determined, to the first area, using a method in accordance with the moving method;
encoding the geometry information of the first three-dimensional point cloud, based on encoded geometry information of the second three-dimensional point cloud that has been moved to the first area; and
generating a bitstream including the geometry information of the first three-dimensional point cloud encoded in the encoding and moving information indicating the moving method selected, wherein
the plurality of moving methods include a method for rotating the second three-dimensional point cloud about a vertical axis of a mobile body, the mobile body including a sensor configured to generate the first three-dimensional point cloud.
