Abstract Due to advancements in digital mapping and remote sensing technology, monitoring built heritage has become more straightforward and convenient. Current individual measurements have numerous limitations, leading to their underutilization. This study suggests a multi-scale data monitoring approach for detecting built heritage deformation by integrating low-cost, wide-area satellite SAR data, high-precision laser scanning technology, and drones surveying technology for quick deployment and computation. Settlement monitoring of Sizergh Castle was conducted to assess the feasibility of the proposed method. The results indicate that the method outlined in this paper can effectively and precisely monitor the settlement and deformation of the heritage building both indoors and outdoors. It can also identify the primary settlement and deformation areas within the building. This greatly improves the efficiency of monitoring heritage buildings and facilitates conservation and repair by maintenance staff.
