A topographic survey is the service performed to determine the configuration, relief, or elevations of a portion of the earth's surface, including the location of natural and/or manmade features thereon. The preparation of a topographic survey requires the expert skill of a Registered Professional Land Surveyor well versed in techniques used to prepare reliable topographic maps. A topographic survey is not a boundary survey, although some approximate property lines may be delineated. The limits of the topographic survey will be determined based on the intended use.
