Abstract. Surveying is the process of determining relative positions of different objects on the surface of the earth by measuring horizontal distances between them and preparing a map to any suitable scale. Differential Global Positioning System (DGPS), Real Time Kinematic (RTK) and Network RTK (NRTK) techniques are the satellite-based positioning techniques that are commonly used in shallow water surveys and shoreline measurements. Operations in Surveying: Control Survey: Made to establish the horizontal and vertical positions of arbitrary points. All such control recovered or established shall be utilized to the fullest extent.
