1. A point cloud data encoding method by an encoder, comprising:
encoding geometry data of the point cloud data;
encoding attribute data of the point cloud data; and
transmitting a bitstream including the point cloud data,
wherein points for the point cloud data are partitioned into a road and an object,
wherein the bitstream includes information for representing a method for the partitioning the point cloud data,
wherein the object is partitioned based on a block including a number of points on an axis,
wherein the bitstream further includes information related to the block.
