472.029  Surveyors and mappers authorized to enter lands of third parties under certain conditions.--Surveyors and mappers may go on, over, and upon the lands of others when necessary to make surveys and maps, and, in so doing, may carry with them their agents and employees necessary for that purpose. Entry under the right hereby granted does not constitute trespass, and surveyors and mappers and their duly authorized agents or employees so entering are not liable to arrest or to a civil action by reason of such entry; however, this section does not give authority to registrants, agents, or employees to destroy, injure, damage, or move anything on lands of another without the written permission of the landowner.
