Case study 1 — Lake water hydrology and bathymetry. Hydrography deals with the measurement and description of underwater features such as depth, tides, currents and bottom profiles. Bathymetric surveys are a specific subset of this which deals with the mapping of the underlying bed. Hydrographic surveys are used for a variety of activities, such as construction, port and harbour maintenance, dredging and coastal engineering and management. Randall Surveys undertakes hydrographic surveys, inshore, lake, reservoir and river surveys, canal surveys and waterway surveys throughout the UK and Europe. Our fully equipped hydrographic teams operate a fleet of vessels equipped with the latest multibeam, sector scan and single beam echo sounders, on-board processing and data displays, real-time centimetre level GPS position fixing, currentmetering, sidescan sonar and magnetometers.

Experience Technology

Surveyors work alongside other engineers, architects and land developers to define legal land boundaries and provide essential engineering support for urban development, large infrastructure projects, the development and operation of mines and the management of the environment and resources. Geospatial engineers are the most recent additions to the engineering family. They use new and developing technologies such as GPS, satellite imagery, laser mapping and fast computing to create complex layers of interconnected geographic information.

Today we can measure position very accurately. We can make maps and look down on the world from airborne and satellite platforms, and visualise the natural and built environment in 3D. Geospatial information constantly reveals new insights about our world and our place in it. Land surveyors play a crucial role in land development, mapping and engineering construction.

Registered land surveyors have a special status as they are the only professional who legally define the dimensions of new or existing property. Surveyors advise land owners, lawyers, builders, architects, planners and other engineers. Surveyors are always in demand with state and federal government, local councils and private companies. Land surveyors are skilled in land measurement, land law, mapping and geographic concepts.

They enjoy working both indoors and outdoors, using modern measurement technology. Cadastral land surveyors in the private sector often begin their careers with outdoor, hands-on tasks. As they progress, they develop their professional skills with client liaison, project development and more legal and business matters. In government departments, graduates initially work on implementing operations relating to land, water, roads, rail or harbours, depending on the department.

They progress to develop policy and regulations and advise on special case or unusual surveys. All surveying relies on geometry, mapping and a spatial brain to fit measurements together. Surveyors are the measurement experts. From the development of the Olympic stadium, the Pacific Highway, the Lane Cove tunnel or the huge new rail networks, to all new major high-rise developments in Australia and internationally, engineering surveyors are there from project launch to completion.

The increased scale and complexity of new infrastructure is very challenging, however, engineering surveyors are assisted by recent advances in measurement technology including:. Engineering surveyors are sought after by major development companies like Leightons, Brookfield-Multiplex, Lend Lease or Meriton, where they oversee all aspects of major urban development including pre- and post-construction surveys, through to ongoing monitoring of finished projects.

Engineering surveyors often begin their careers in the field, leading parties responsible for the set out of complex projects. They go on to manage teams of survey parties and work closely with project managers and allied professionals to ensure projects are completed on time and on budget. As projects become more ambitious, the experienced engineering surveyor must design new techniques with the latest technology to ensure challenging building specifications are met.

There is a lot of personal satisfaction in the work of an engineering surveyor as the final project is a constant reminder of the contribution they made to the completion of the project. The expansion of mining in Australia has produced a desperate need for mining surveyors who are an integral part of the mineral production process. Mining surveyors draft mine plans and determine how the mine will operate efficiently and safely, as well as helping to minimise environmental damage and remediate old mine sites.

Mining surveyors work at all kinds of mines from open-cut iron ore mines in Western Australia to underground coal mines in New South Wales and Victoria, as well as overseas. Mining surveyors must take exams administered by the Board of Surveying and Spatial Information after they graduate to become registered mining surveyors. Mining surveyors usually begin their careers in a hands-on role, dealing with the day-to-day operations of the mine.

After registration, they supervise teams of surveyors and liaise with mine managers and allied professionals. Some may choose to take further study and become more involved with the business side of the mining company, while others will develop their technical skills and advise on new techniques to improve yields, cut costs and maximise profits. This highly paid segment of the surveying profession is an attractive option for professional surveyors.

Mining surveyors get a lot of personal satisfaction from improved mine yield and the smooth operations of the mines for which they are responsible. The work is very 3-dimensional and a mining surveyor must have a good spatial awareness. Hydrographic surveyors also measure the impact on the coast and offshore structures of the ocean, climate change and development. Hydrographic surveyors monitor marine environments and prepare digital charts for navigation, as well as supervising the offshore construction of pipelines and submarine cables, drill platforms and wind farms, piers and seawalls.

Employers in Australia and overseas include governments, oil companies, such as Shell and Chevron, and engineering companies building new energy and transport infrastructure. After graduation, it is possible to gain professional recognition of their specialised skills through hydrographic certification. When the Pasha Bulker was beached off Newcastle in , hydrographic surveyors helped salvage operations by mapping an exit route, avoiding submerged rocks. Hydrographic surveyors were also involved in the recent refloating of the Costa Concordia off the coast of Italy.

A career in hydrographic surveying can be extremely exciting and rewarding with outdoor work on the rivers and seas or in the office carrying out important calculations. Modern geospatial technologies are used to create solutions in an ever-widening range of industries. Currently, there are more well-paid jobs than there are geospatial engineering graduates — in private industry and the government sector, in Australia and overseas.

Geospatial engineers face the challenge of managing and combining huge volumes of geospatial data from various measurement techniques of differing precision and at differing times. This includes robotics and machine automation, smart buildings and smart infrastructure, car navigation systems, transport logistics and new digital services for mobile phones.

Geodesists are principally researchers who work with the fundamental coordinate framework that maps our world. This kind of research is usually done at the postgraduate level and geodesists work in universities and federal and state government agencies, such as Geoscience Australia and the NSW Department of Lands, which are charged with the maintenance of the national or state coordinate frameworks. GIS specialists use ongoing developments in digital technology to enhance the ways that information can be used.

Integrating these databases in real time with GPS positions or other devices opens up a new world of location-based services — one of the many uses of GIS. This is about linking social networks, navigation and business directories on mobile phones, to access information in new ways, create new services or just find your friends. Location-based services use powerful applications from Google, Apple, Facebook,Microsoft and others.

GIS is used in mine management to optimise work flows. It is used by councils for asset management and by emergency management authorities to coordinate activities, especially during large disaster events. GIS is used in traffic management and environmental monitoring, and is increasingly being used across the corporate sector, especially in the insurance industry. Ultimately web services of geo-data can be linked to provide a spatial data infrastructure SDI that could be used to benefit everybody.

GIS specialists ensure that these layers inter-link for analysis and planning, to meet the needs of the community and our changing natural and built environments. Surveyors and geospatial engineers use modern satellite, aerial and land-based positioning technology to provide mapping services for flood plain studies, coastal monitoring, natural resource management, agriculture, sustainable development, and many more applications.

Transportation in Ghana over the decades has dominantly depended on land either by the road and rail systems. Access roads to coastal and lakeside settlements have not been the best due to the bad road nature and possibly the unavailability of link roads to the settlements. This kind of movement takes so long a time and for that matter its effect on perishable goods either by expiring or getting rotten. In the case where access exists, due to the bad nature of the roads and most often only one narrow access, vehicles are either unable to get to the production sites or vice versa. The use of fishing canoes has been the available mechanism for transporting people and goods which has endangered lives over the past periods due to unavailability of safety measures. Ghana is fortunate to have a major water body along the southern boundary of the country, i. Along this lake and the coast are towns, communities, villages that depend on the use of these water bodies for their livelihood and business activities. Moving from one settlement to the other either along the water body or across has always been a huge problem.

A NOAA survey ship uses its multibeam echo sounder to conduct hydrographic surveys. Multibeam sonar measures the depth of the sea floor by analyzing the time it takes for sound waves to travel from a boat to the sea floor and back. Many of the things you buy in the store probably traveled, at some point, on a ship. The U. Over 1. Keeping our marine transportation system functioning in a way that is safe, efficient, and environmentally sound requires information about water depth, the shape of the sea floor and coastline, the location of possible obstructions, and other physical features of water bodies. Hydrography is the science behind this information, and surveying is a primary method of obtaining hydrographic data. And so began the history of the Survey of the Coast, an organization that would go through changes to its name and structure, but not its fundamental mission:

Engineers, contractors, environmentalists, water management, city, state and federal agencies trust Arc for their most complex projects.

Hydrographic survey is the science of measurement and supervision of marine waters and subaqueous relief for the purpose of safe navigation of vessels and marine conservation. It applies to survey of marine waters, as well as that of lakes and rivers, which is collectively referred to as hydrographic survey or waterway survey by several nations. Measurement of the conducted water regions can be compiled into navigation chart. Initiated from hydrographic surveying, marine survey extends itself to the aspects of marine geodetic survey, submarine topography survey and other marine special survey. Hydrographic survey deals with a wide variety of subjects, of which strong emphasis is placed on positioning survey, bathymetric survey, sweeping survey and tide survey, as well as bottom characteristics sampling. Traditionally, survey of bathymetry is made directly with a sounding rod or a hand lead. Modern bathymetric survey is generated to measure the depth with the principle of echo: Airborne Laser Bathymetry can be conducted in a relative clear water region. The information of chart water depth refers to the vertical distance between a certain point in the water and sounding datum. As a result, besides field survey, water depth can be figured out until the completion of acoustic wave velocity correction, location and slant distance rectification and draft amendment.

Strong emphasis is placed on soundings, shorelines, tides, currents, seabed and submerged obstructions that relate to the previously mentioned activities. The term hydrography is used synonymously to describe maritime cartography , which in the final stages of the hydrographic process uses the raw data collected through hydrographic survey into information usable by the end user. Hydrography is collected under rules which vary depending on the acceptance authority. Traditionally conducted by ships with a sounding line or echo sounding , surveys are increasingly conducted with the aid of aircraft and sophisticated electronic sensor systems in shallow waters. The product of such hydrography is most often seen on nautical charts published by the national agencies and required by the International Maritime Organization IMO , [4] the Safety of Life at Sea SOLAS [5] and national regulations to be carried on vessels for safety purposes. Increasingly those charts are provided and used in electronic form unders IHO standards. Governmental entities below the national level conduct or contract for hydrographic surveys for waters within their jurisdictions with both internal and contract assets.

Engineering and land survey are fundamental to the design, construction and navigation of infrastructure projects from small to national scale such as buildings, road and rail networks. Hydrographic Surveyors contribute to safety of navigation and port management for seas, rivers and lakes, and underwater infrastructure projects such as pipelines and offshore wind turbines.
