PROBLEM TO BE SOLVED: To provide a noise removal method of laser data which does not degrade the laser data and can be automatically processed. SOLUTION: The noise removal method of laser data removes noise data from a laser data group, which includes planar position data and altitude data acquired by using an aircraft laser scanner. A representative value of a focused mesh is added to the focused mesh and the altitude data of surrounding mesh is statistically processed and set after mesh generation of the laser data group based on the planar position data, then a statistical verification on the basis of the representative value, which is applied to the focused mesh for each altitude data in the focused mesh, is conducted and the noise data is separated and removed.
