Over time, the earth's plate moves actively and dynamically, causing crustal deformation. Deformation can occur linearly with a constant movement value every year and also nonlinear due to sudden plate movements that cause tectonic activity. In the land administration scope, the deformation can cause changes in the shape, position, and dimensions of measurement and mapping objects. Currently, there are several potential earthquakes near Bali Island. This research was conducted to investigate the changes that occur in measuring and mapping objects (land administration) in Bali Province. The land administration data employed in this study is the simulated gridding data and the real field measurement data. The deformation data used is based on the deformation model data created by the Geospatial Information Agency (BIG), which accommodates the linear movement model-based block motion model. Based on the simulated velocity, the deformation over 14 years caused horizontal displacement up to 86.2 cm. In addition, sudden movements due to an earthquake and its following postseismic deformation also can affect the changes in the position of land administration data. This change in position has potential problems in mapping, such as gaps and overlaps, without including a proper time-dependent coordinate reference system that accommodates the deformation model.
