Numerical cadastral surveying indicates measuring/mapping boundaries, or areas of land, upon the request of local authorities or interested persons in order to register the land in the cadastral record, or to mark the land according to what is registered in the cadastral record.
The purpose of this kind of surveying is to map the precise locations of sewage pipes, gas pipes, underground tracks, and communication lines. Currently, surveying services are required by government agencies, municipal organizations, and government investment organizations in order to establish attributional information data to enable scientific and systematic management.
