INTERNATIONAL TGS, PGS, and Schlumberger to conduct 3D seismic survey offshore Malaysia The 6,885km² survey acquisition is due to start in June 2023. Credit: Nathan Forbes on Unsplash. GS and its partners PGS and oilfield services company Schlumberger have secured pre-funding for a multi-client 3D seismic survey offshore Malaysia. Planned to be carried out in North Luconia Province of the Sarawak Basin, the 6,885km² survey acquisition is due to start in June 2023. It is scheduled to conclude in August 2023 while the final deliverables are anticipated in Q2 2024. TGS noted that the interim results would be made available to assist with evaluation of the early acreage. NUVIEW on mission to map entire globe in 3D with LiDAR for first time NUVIEW, an American Earth observation and geospatial technology company, announced that it is building the first commercial LiDAR satellite constellation which will map the entire land surface of the Earth in 3D for the first time. The announcement was made during the Geospatial World Forum in Rotterdam, the Netherlands. The company has $1.2 billion dollars in early adopter agreements. Currently satellite imagery provides a 2D view of the planet, with only an estimated 5% of the Earth’s landmass having been mapped with LiDAR. The limited depth and accuracy restrict its use for challenges such as climate change, disaster response, sustainable farming, conservation, and forestry. NUVIEW’s technology will be powered by a constellation of satellites. It will collect data more than 100 times faster than current commercial aerial solutions. This will give 3D mapping. Credit NUVIEW NUVIEW access to the geospatial market which is expected to grow to a $1.7 trillion industry. “NUVIEW is thrilled to be leading a new era in geospatial technology to provide the first, most complete, high-resolution 3D point cloud of the Earth’s surface,” says Clint Graumann, CEO & Cofounder of NUVIEW. “Our LiDAR satellite constellation will offer a wealth of information that has never before been available at scale, driving innovation and progress throughout numerous industries and revolutionising the way we understand and interact with our planet.” Cepton is developing groundbreaking LIDAR technology to make driving safer The survey is the second phase of a multiyear contract, which was awarded initially by Malaysian firm Petronas in 2020. The contract was awarded to acquire and process up to 105,000km² of multi-client 3D data in the Sarawak Basin over a period of five years. The latest survey builds on this project’s initial phase in the Sarawak North Luconia Province. TGS CEO Kristian Johansen said: “TGS has built an expansive multi-client data library across the Asia-Pacific region, and we are pleased to return to the Sarawak Basin with our partners. Sarawak is an area that has recently experienced multiple oil and gas discoveries, and we expect this to be a very important basin for future exploration. Cepton Inc (NASDAQ:CPTN) is making a name for itself in the fast-paced world of automotive innovation with its game-changing technology poised to revolutionize vehicle safety. A leading Silicon Valley startup, Cepton has harnessed the power of LIDAR to enhance the security and autonomy of everyday vehicles. In an exclusive interview with Proactive, Cepton’s CEO Jun Pei shared insights into the burgeoning world of LIDAR and its transformative impact on the automotive industry. LIDAR, short for Light Detection and Ranging, is an optical device that measures the distance between objects by emitting laser pulses and analyzing the reflected light. While this technology has been around for decades, recent advancements in miniaturization and technical capabilities have enabled its application in modern vehicles. Contrary to popular belief, LIDAR's first application is not autonomous vehicles; instead, it serves as a powerful safety device. Pei emphasized that LIDAR equips vehicles with the ability to perceive objects in their surroundings, detecting obstacles and enhancing safety for drivers and pedestrians alike. "As we drive toward a safer future, LIDAR plays a pivotal role in reducing accident rates and instilling a sense of certainty and comfort while driving," Pei explained. 6 May-June issue l 2023 www.africasurveyorsonline.com
INTERNATIONAL MBARI, 3D Aim To Create New LIDAR Seafloor Mapping Technology Imaging the structure of the deep seafloor is critical to understanding the biology and ecology of the largest living space on our planet. But to date, only about 20 percent of the ocean floor has been mapped at a resolution useful for scientific study. For the past 10 years, MBARI has worked with 3D at Depth to develop innovative tools to map the seafloor using lidar technology. Now, this partnership aims to create the next generation of subsea lidar technology that can generate detailed high-resolution maps of underwater features. “To meet our goal of surveying the complex and rugged terrain of the deep seafloor at one-centimeter resolution, we’re working closely with 3D at Depth to develop enhanced lidar technology that will be smaller in size and weight and require less power, making it ideal for deployment on MBARI’s robotic submersibles and eventually, our autonomous robots too,” said Dave Caress, a MBARI uses lidar technology from 3D at Depth to visualize the deep seafloor at high resolution. This year, MBARI and 3D at Depth will build and test a more portable lidar system designed for seafloor mapping.

These projects are truly a win-win for both organizations as it provides MBARI with a tool to meet their scientific goals and helps us improve our subsea lidar systems for diverse robotic platforms,” said 3D at Depth CEO Carl Embry. IOGP Releases Land Survey Data Model The International Association of Oil and Gas Producers has released its Land Survey Data Model (LSDM), continuing the practice of its Geomatics Committee of maintaining an "out-of-the-box" data model template to manage survey data within a geodatabase. The LSDM is an industry standard template for operators to maintain land survey data, mainly acquired for the oil and gas industry. The model enables the storage of key geospatial and nongeospatial descriptive and feature-specific elements of the following land-based survey activities: • Design, engineering, and construction surveys of infrastructure and facilities including proposed routes, as-found, as-left, as-installed, and as-built positions; depth of burial; general/ detail layout surveys—for company or third-party facilities that may overlap or affect exploration and production infrastructure (e.g., those owned or operated by utility companies) • Land and topographic surveys, including elevation (e.g., contours, spot heights, relief shading, terrain modeling), natural and man-made features, explosive remnants of war, archaeological sites, and underground services surveys • Geodetic and survey control network surveys, including coverage, line of sight, and monumentation • Land survey measurements, survey line plans, and similar documentation for unmanned aerial vehicle (UAV)/ light detection and ranging (LiDAR) operations or similar (planned and asexecuted) • Vegetation and land use surveys • Imagery from satellite, UAV, and crewed survey flights (e.g., satellite imagery, LiDAR, aerial photography) • Right of Way (ROW) surveys and surveillance (ROW anomalies and The model is an industry standard template for operators to maintain land survey data, mainly acquired for the oil and gas industry. | Image Source: IOGP observations) such as pipeline route surveys, pipeline and facility UAV inspection, and access road surveys • Administrative boundaries and cultural information (e.g., roads, railways, rivers, habitation) • Geophysical/seismic, exploration and reconnaissance, geohazard, shallow and intermediate geology surveys • Geotechnical soil investigations • Environmental baseline and monitoring surveys • Infrastructure condition and subsidence monitoring surveys A detailed description of the data model may be found in the IOGP Report 640 – LSDM Guideline for Delivery and Use report, which is included in the package.
