Sjoerd van den Brom
Survey Manager
The Netherlands

Sjoerd van den Brom studied at Amsterdam Natical College and gained a bachelor degree in Hydrography in 1986. He joined Boskalis in 1989 as a field surveyor working on international derdging projects. His current position is manager of the Boskalis Survey department. Sjoerd has a strong engament in Hydrographic education, was a member of the Industrial reference board for Hydrographic education in the Netherlands for 10 years, of which he chaired the board for 8 years. He is a member of the ‘Conseil Industriel’ at Ensta-Bretagne and gives guest lectures on Survey for Dredging at both Plymouth University (UK) and Ensta-Bretagne (Fr).

Gathering Geospatial Data in Boskalis Mining Operations
Royal Boskalis Westminster N.V. is a leading global services provider operating in the dredging, maritime infrastructure and maritime services sectors. The company provides creative and innovative all-round solutions to infrastructural challenges in the maritime, coastal and delta regions of the world with the construction and maintenance of ports and waterways, land reclamation, coastal defense and riverbank protection. In addition, Boskalis offers a wide variety of marine services and contracting for the offshore energy sector including subsea, transport and heavy lift (through Boskalis Offshore) and towage and salvage (through SMIT). It also has strategic partnerships in the Middle East (Archirodon) and in terminal services (Smit Lamnalco). With a versatile fleet of over 1,100 units Boskalis operates in around 75 countries across six continents. Including its share in partnerships, Boskalis has approximately 14,000 employees. Almost all activities Boskalis is engaged in have strong geospatial components since we either change the ‘land- or seascape’ or perform an activity relating to an object at a specific –sometimes changing- location within the land- or seascape. A further factor of major influence is that a significant part of our activities take place under water, where a person unfortunately cannot see, or in some cases as in the Suriname example in a very inaccessible part of the world’s landscape. Since we change the landscape continuous updates are needed to provide our production units with accurate, high resolution digital data. The Boskalis Survey department is tasked with providing geo-referenced and geospatial information needed for efficient and effective execution of Boskalis activities worldwide. As an example the Lelydorp bauxite mining project will be presented.
Richard Musselman
Operations Support Engineer
Kinross Gold Corporation

Richard has worked in mining and surveying in Nevada for over 25 years, working at the Round Mountain Gold mine the past 16 years as the Chief Surveyor/Operations Support Engineer. He has experience in both open pit and underground operations. Early in his career he started using Trimble GPS equipment and has been a devoted user ever since. He was a mining industry leader in using robotic high wall monitoring solutions in the infancy of that technology. Richard is proud to be a third generation hardrock miner; three of his four children also work in the industry.

Using Trimble 4D Control for High Wall Monitoring at Round Mountain Gold Mine
Fast, reliable, and accurate high wall movement monitoring is critical to ensure safe production in a large operating open pit mine. In 2011, Kinross’s Round Mountain Gold Corporation and Trimble with Monsen Engineering teamed up to install an advanced total station high wall monitoring system at the central Nevada gold mine. The Trimble 4D at Round Mountain uses two robotic S8 total stations, six NetR9/Zephyr/prism GNSS monitored locations, an array of ten back sights, and a base station. The S8's are housed in climate controlled pit-edge buildings and GNSS station hardware is housed and powered using fabricated mobile solar trailers. Ground movement is measured every two hours at several hundred prism locations around the pit. Components communicate using the mine's existing 802.11 wireless network. The prism and GNSS location data is processed using a production server and stored in a virtualized SQL database server. Additional campaign monitoring is collected using a post or tripod mounted Trimble VX and a TSC3 data collector downloaded to the system daily. Reporting is available through the T4D Control with system alerts and T4D Control Desktop through a web interface. RMGC has plans to continue optimizing the system, to import historic GeoMoS monitoring data, and to develop site specific reporting and hardware customizations. Installation of the T4D system marks a significant improvement in data quality, quantity, and integrity at Round Mountain.

Perspectives of Remote Sensing and GIS for Mining Areas
Mining areas are special areas in the environment. There are in fact several different subareas, which are related to the mining area phenomenon. These are underground mining locations active and abandoned, open mines which are active, of course, reclaimed areas and damps. Talking about abandoned mines, we are facing in prevailing cases land subsidences. To prevent hazards, a detailed GIS data model created from detailed mining maps in 2,5 dimensional system is necessary. This system allows detection of possible location of subsidences by geotechnical models from mapped situation of mining activity. The open mines and dumps has to be mapped for GIS data model to record an updating of the continuing mining activity including additional infrastructure of the mine. The data are 3D measurements usually from photogrammetry and/or laser scanning evaluations. The individual task is monitoring of reclaimed areas and dumps. The monitoring should be stored and analyzed in 2,5D GIS. The monitoring should comprise both land cover and DEM. Land cover processing must be focused on development of reclaimed areas and physical and chemical activity of dumps “leakage of chemical materials, heating, etc. The DEM processing should monitor the new terrain stability, slope stability and subsidences.

More Detail, Better Insight, Accurate Analysis –WorldView-2 Power of 8 Bands
WorldView-2 is the only commercial satellite capable of collecting high resolution 8 band multi-spectral imagery in the world. Using a combination of these bands we will demonstrate how you can extract land and water features with better accuracy and clarity, providing insight and analysis never before seen in high resolution imagery.

Role of New Disruptive Technologies in Delivering Information
Information about availability of raw materials, water, energy resources, potential supply risks, environmental and social aspects are therefore crucial for securing reliable access to natural resources in the context of a growing pressure. Geoscientific knowledge underpins industry development as well as public policies and regulations for the benefit of society. Geological surveys have been key geoscientific information providers for many years, but very often, in a way that made it really usable only by geoscientists. Today, this information has to be made available for a wide community of users (industry, public authorities, scientists, NGOs…) in a very open manner, facilitating its understanding, and re-use. The main challenge our community is facing relies in a radical cultural change. We must be ready to contribute to the large network of scientific and technical information infrastructures (not limited to the geoscientific disciplines) that are rapidly growing, make sure our authoritative information is delivered with traceability, integrate crowdsourcing whenever it is possible. With this prerequisite condition, new disruptive technologies will provide us opportunities to collect, manage, and deliver the information in an efficient way at a reasonable cost for the benefit of our current and future users.
