Control surveys are carried out to establish precise horizontal and vertical positions of reference monuments. These serves as the basis for subsequent surveys for projects such as topographic and hydrographic mapping, boundary delineations, road and construction planning, design and layout. We employ GPS/GNSS for the establishment of control points in static post-processing and RTK mode.
