Cadastral Surveying is the sub-field of surveying that specialises in the establishment and re-establishment of real property boundaries. It is an important component of the legal creation of properties. A cadastral surveyor must apply both the spatial-measurement principles of general surveying and legal principles such as respect of neighboring titles.
