UNDERGROUND UTILITY DETECTION

Vision use both non-intrusive investigations and direct access survey methods to provide a clear understanding of buried services, utilities and hazards necessary for many aspects of construction projects. This data reduces the need for expensive excavations or delays by identifying safe and clear areas for all excavations, boreholes, piles and trial pits. Preparation of detailed digital CAD drawings based on accurate topographical/land survey information can be essential at the detailed design stage to use or avoid existing underground utilities, drainage networks and obstructions and plan new services more efficiently. All our underground survey teams are fully trained and equipped with the latest technology including multi-frequency electro-magnetic equipment, CCTV drainage cameras and dual-frequency Ground Penetrating Radar (GPR).

3D LASER SCANNING

A Revolution in 3D Scanning the laser scanners are changing the way the industry looks at 3D. Both capture high quality scans at exceptionally high speeds as they deliver superior accuracy and range. Users now have more options to choose from to handle a wider range of projects with the same, powerful Trimble Lightning technology, making our laser scanners the best values on the market. Once the fieldwork is done, rely on Trimble RealWorks software to efficiently, effectively manage large data sets and produce compelling deliverables.

Mobile Laser Scanning

Mobile Laser Scanning (MLS), also known as Mobile LiDAR (Light Detection and Ranging), is a remote sensing technique used to collect highly accurate 3D spatial data of the surrounding environment from a moving platform, such as a vehicle or aircraft.

AERIAL SURVEYING

Vision International uses a number of aerial imagery acquisition platforms to provide mapping at various scales and formats for clients, according to their requirements. Using a Trimble UX5 Unmanned Aerial Vehicle (UAV) based in Kuwait, Vision International is able to respond rapidly to requests for the flying of aerial photography, with the height of flying determining the scale and accuracy of the resultant mapping. Deliverables to the client can be either Digital Terrain Models ( DTM ) , or rectified orthophotos, or full, contoured topographic mapping. The use of the UAV makes the preparation and updating of base mapping for Geographical Information Systems easy, accurate and fast, responding immediately to requests by clients. The company also has a formal agreement with IIC Technologies, an international surveying company with offices globally, for the flying of aerial photography using their own aircraft, using an Intergraph DMC II230 digital camera.

Bathymetric surveying plays a crucial role in understanding and managing the underwater environment. By accurately mapping the seabed and water depth, bathymetric data supports a wide range of applications essential for sustainable marine development, navigation safety, and environmental conservation.

Multibeam sounder

Multi-beam surveys are used to gather detailed information about the features on the seabed by measuring multiple depths from a single transducer array at high resolution. The result is a highly accurate 3D picture of the sea floor. It has many added advantages over the single beam surveys. It provides higher resolution data as per the International Hydrographic Organization (IHO) standards and is more time efficient, has less errors and captures additional data such as the seabed texture and type.

Singel beam

In single-beam bathymetry, an echo sounder is used to measure the depth by sending out an acoustic signal. This does not provide an image as detailed as one that is produced by multibeam bathymetry. Even though Multibeam technology has largely superseded single beam, single beam still remains a valid methodology for surveying. For shallow water environments where the time required to achieve 100% in sonification with a multibeam sonar is excessive or beyond a client’s budget, single beam is used.

Sub Bottom profiler

Sub-bottom profiling systems identify and measure various marine sediment layers that exist below the sediment/water interface. These acoustic systems use a technique that is similar to single beam echo sounders. A sound source emits an acoustic signal vertically downwards into the water and a receiver monitors the return signal that has been reflected off the seafloor. Some of the acoustic signal will penetrate the seabed and be reflected when it encounters a boundary between two layers that have different acoustic impedance. The system uses this reflected energy to provide information on sediment layers beneath the sediment-water interface.

Side Scan Sonar

Side Scan Sonar is a category of sonar systems used to create an image of the ocean floor. This image can be of very high quality, and can discern objects within the scan area with clarity, regardless of the murkiness of the water. The scan is done by a “tow fish”, or using a side mounted transducer, which is positioned in the water off the side of the survey vessel. The tow fish sends and receives soundwaves, which are then processed by a computer.

Hemisphere DGPS

Hemisphere Differential Global Positioning System (DGPS) is a technology used for accurate positioning and navigation.

TIDE OBSERVATIONS

Tide observations are checking and predicting how the sea level changes over the course of the day. To do this, we use a tide gauge.

ADCP Nortek

Acoustic Doppler Current Profiler (ADCP) is an instrument used to measure water currents in oceans, rivers, and lakes. It operates on the principle of the Doppler effect, which is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source.

Ambient Noise

Ambient noise refers to the background noise present in a particular environment, typically resulting from a combination of natural and human-generated sources.

Magnetometer

A magnetometer is an instrument used to measure the strength and/or direction of magnetic fields.
