Fields of Expertise
Mine Surveying
iMO is experienced in dealing with the common problem of insufficient topographical information. Where conditions are unfavourable we are spurred on to find fast and reliable new technologies to acquire terrain data. Since 2001, iMO has offered technology-driven solutions for topographical surveys focusing on terrestrial and airborne laser scanning in combination with GNSS surveys.
iMO’s offers the following modular service:
- Evaluation and selection of survey technologies
- Specification and procurement of survey equipment
- Realisation of geodetic base surveys
- Establishment of geodetic survey networks
- Realisation of terrestrial laser scanning surveys
- Management of airborne laser scanning projects
- Realisation of airborne laser scanning projects
iMO is specialised in the performance of surveys in remote areas such as West Africa. We relish the challenge of operations in difficult conditions, such as in areas where electricity supply or transport networks are unreliable, and will devise our own innovative modifications based on up to the minute technology. If other aspects of your operation don’t go according to plan, you can rest assured that our advanced project management skills will mean we adapt quickly to changing circumstances and deliver what you need.
Terrestrial Laser Scanning (TLS)
Terrestrial laser scanning is a time saving and accurate surveying technique for the acquisition of 3D survey data. It is used by the mining and civil engineering industry to derive surface models but also by the film industry and to assist with forensic investigation and heritage protection. iMO provides terrestrial laser scanning as a service for mining clients for a variety of purposes including annual inventory, year end survey, slope monitoring, reverse engineering, geological modelling and contractor supervision.
Airborne Laser Scanning (ALS)
Airborne laser scanning is a topographic land mapping method which can perform timely and cost-effective mapping of large areas with a high point density and a high degree of accuracy. The method is performed by an aircraft-mounted system which emits a regular stream of laser pulses which are reflected by the ground and the objects on it. ALS data acquisition can be combined with other surveying sensors such as digital metric cameras.
iMO offers a modular choice in their project management for airborne laser scanning projects. This includes project evaluation, definition of work scope, compilation of tender documents, ground preparation, ground survey works, permissions, contractor supervision, quality control, data processing and data management.
GNSS - Applications
GNSS (GPS, Glonass) surveying techniques have improved tremendously in recent years and have become powerful tools for positioning and navigation. GNSS has two major advantages over other surveying equipment: its operation is weather independent and does not require inter-station visibility and it is ideal for supporting terrestrial laser scanner surveys by allowing direct positioning of the scanners. iMO uses the latest GNSS equipment from leading manufacturers. The GNSS static method allows the establishment of highly accurate and reliable geodetic networks. Real-Time Kinematic (RTK) can be applied for surveying large numbers of points or for stake-out surveys. In the case of aerial surveys, GNSS equipment is used as reference station.
