The purpose of this subchapter is to enable surveyors to have access to survey monuments, triangulation stations, traverse stations, leveling stations, section corners, quarter-section corners and sixteenth-section corners, locations, and other evidence needed in conducting or preparing for surveys or in preserving such monuments, triangulation stations, traverse stations, leveling stations, section corners, quarter-section corners and sixteenth-section corners, locations, or other evidence. It is particularly recognized that at times it is necessary for a surveyor to tread on property not in his or her survey contract because the boundaries and corners of any parcel of land are necessarily also those of adjoining parcels and because the location of boundaries and corners often are affected by the location of some that are remote and not adjoining.
