Measurement by geodetic method can be used for the determination of deformation on an object or area. One of the geodetic methods that can be used in the measurement of deformation is Terrestrial Laser Scanner (TLS) episodic. Episodic TLS is a measurement method for determining the three-dimensional position of an object (in a particular coordinate system) which is performed several times of measurement with a certain period. The final task study aims to determine the size of deformation in the Sidoarjo mud area using episodic TLS data. In addition, TLS data in Musi Banyuasin is also used for simulation deformation measurements, where calculation of yield difference between two filtering methods (manual and automatic) is used. <br /> <br /> <br /> The result both of the LUSI episodic TLS data processing and the Musi Banyuasin TLS data processing show that value of the deformation and value of simulated deformation can be obtained with the precision up to centimeter. The deformation in the area of LUSI caldera vary spatially by -0.5 to 1 meter. In the TLS simulation data, the measurement by the point to point method resulted in average value of the deformation result of 5.8 to 11.4 cm and the surface to surface method yielded an average value of the deformation result of 4.5 to 19.1 cm. The difference in outcomes between the two deformation measurement methods is 0.1 to 9.7 cm. <br /> <br /> Measurement by geodetic method can be used for the determination of deformation on an object or area.
