Hydrography is a science that produces charts and maps with points that have the following characteristics - they show latitudinal and longitudinal position, they show depth of water at that position with chronological compatibility to tidal variations and they also show distance from particular land features like coastline indentures (Mason, 2007).

Since then the science has evolved from a crude form of conjecture to a fairly accurate predictive one.
This paper prepares a report form of investigation in which the implications of converting hydrographic surveying based on single-beam echo sounders to multiple-beam ones shall be studied and considered in detail to assess feasibility and functional efficacy with particular reference to Medway Ports, UK. To initiate this noble venture it is first necessary to study a little of Medway Port, Kent, UK, especially in detail to its known navigation features.
The Medway Ports authorities define the Medway River as one of the principal trade arteries of the United Kingdom with particular utility to the South East of England through which this river flows before ending into the sea strategically near to the English Channel and the North Sea (Overview, Medway Ports, 2007). This proximal position to two main European trade routes, the port's efficient functionality and its easy accessibility to its hinterland by road, rail and water has eventually evolved it into a port of choice for many export and import operators. Cargoes such a fresh produce, forest products, new vehicles and steel and containers pass through it to and fro British soil (Overview, Medway Ports, 2007).
Actually, the Medway Ports authority is a statutory one and is responsible for a 27 mile stretch of water that is a combination of the Medway and Swale rivers. The authority is responsible for maintaining the rivers and for providing and coordinating pilotage and vessel traffic services to ensure safety of all river users including pleasure boat ones (Overview, Medway Ports, 2007). The Ports are mainly a combination of the Sheerness and Chatham docks (Peel Ports Group, Medway Ports, 2007). Britain's first LNG handling terminal was constructed at the Isle of Grain within the Ports complex (Peel Ports Group, Medway Ports, 2007).
Pilotage services provided by the Ports authorities are compulsory for vessels of 50 metres and above in length.
The Medway Conservancy Board has taken over hydrographic surveying of the Medway Ports system from the Royal Navy Hydrographic Inshore Squadron since the 1960s. Presently, it has tow crafts at its service - the 18.9 metre Medway Surveyor that surveys the main reaches of the Medway and the deeper offshore waters and the 6 metre Medway Recorder which surveys the berths and shallower waters. Both vessels have permanently installed echo sounders that can also work as side scan sonar recorders (Hydrographic Service, Medway Navigation Service, 2007). It is assumed that the echo-sounders are all single beam ones.
Hydrographic surveying is undertaken in two types of operational locations - oceanic or relatively deeper offshore waters and relatively shallower inshore waters. As has already been evidenced with Medway Ports, the former locations are usually surveyed by larger survey ships like the Medway Surveyor and the latter locations by smaller

Regarding the application of survey networks, there are terrestrial survey networks; GPS survey networks, topographic survey networks, geodetic survey networks, engineering survey networks and so forth. Furthermore, the survey network is divided into free networks and constrained networks.
The public police lack appropriate resources to deal with such crimes, since they have to stick to their budget, and as a result, private security has emerged and is increasing. Private security guards are commonly hired by entrepreneurs to guard the business from theft; in such a scenario, the police are not required, in countries where local mafia is present firms prefer hiring private security, (De Melo & Ofer 1994 p40).
The surveys are consistently accurate to the sub centimetre level. When the GPS base is established on a known latitude and longitude, and if post processing is applied to the base station, standardized coordinates for GIS mapping is provided, or any other application that requires coordinates based on latitude and longitude, UTM zone, State Plane Zone, or any of the standard zones and map projections.
There are also two kinds of QS the Private Practice and the one who is employed in a construction company. The comparison between the two surveyor are further discuss in this paper. Quantity surveying is a superb career for men and women who have the desire to involve themselves in the exciting world of construction and development.
However, GPS had already a remarkable impact on surveying, first as a technology for the "control surveys", for which the purpose was first introduced into many countries during the early 1980's before the full satellite constellation was available to navigation users.
The purpose of which is it can operate in any kind of weather, it has a non-stop operation which means it can operate 24 hours and is always available anywhere. It has also a very economical use, it increases productivity, customer service is improved and the accuracy (3-D data, Velocity timing) is not a question.
suring system, an image pickup unit for taking an image in the measurement range, an image processing unit for performing image processing to extract edges from the image picked up, and a control arithmetic operation unit for selecting a point near the edge as a measuring point
The facility in this case is currently being used in accordance to its use and this therefore means that improvements in the property will help in increasing the usefulness and the functionality to the public.
The author of the paper advices that considering the ethics, liability and legal manners for a professional surveyor, a surveyor should justify his actions at all times, be able to demonstrate personal commitment in abiding by the ethical standards in maintaining integrity of professionalism.
