Optical surveying is a field of research that involves using optical instruments and technologies to conduct surveys and measurements of various objects, structures, and landscapes. This can include the use of devices like total stations, theodolites, and laser scanners to capture precise and detailed data on the geographical features and dimensions of a particular area. Optical surveying is commonly used in construction, engineering, archaeology, and geology to map out and analyze the topography of a site, monitor structural movements, or create accurate 3D models. This research area plays a crucial role in the accurate and efficient collection of spatial data for a wide range of applications.
