Multiplatform Lidar Use in Digital City Projects

CHCNAV AlphaUni 900 Application Case
Following its emergence more than a decade ago, digital twin technology has developed to become a complex and comprehensive technical system that supports the construction of new smart cities. It is also an advanced model for the continuous innovation of intelligent urban development and a future form of modernization of the combined ‘virtual and real’ world. (This article is brought to you by CHCNAV) The establishment of the digital twin city brings to the forefront high-level topographic tools that are able to deliver comprehensive, multi-dimensional, large-scale and high-resolution datasets. Traditional methods of collecting and representing 2D spatial data, such as... (read more)

Extraterrestrial Hydrography

While there is still lots of ocean mapping work to do on Earth, oceans situated elsewhere in our solar system hold plenty of mysteries too, writes Wim van Wegen in this column. The oceans on our planet remain largely an unexplored world, far from divulging many of their secrets. Seabed 2030, which is a joint project between the Nippon Foundation of Japan and the General Bathymetric Chart of the Oceans (GEBCO), aims to collect all available bathymetric data in order to produce the definitive map of the world’s ocean floor by 2030. As of today (and despite many years of... (read more)

Multibeam Lidar for Mobile Mapping Systems

Features and Productivity
Various multibeam Lidar sensors are suited for mobile mapping. Read this article to learn more about their features and productivity. In mobile mapping, geospatial data is acquired by one or more cameras and/or one or more Lidar sensors mounted on a vehicle that moves over land, through water or through the air. The distribution of Lidar beams over the scene may be realized by a spinning mirror or by a solid-state device. Multiple beams may be emitted simultaneously, and single or multiple returns may be captured. In the case of the selected Lidar sensors, the mechanisms for distributing emitted beams... (read more)

Using the Apache Unmanned Survey Vessel

Techniques in Bathymetric Survey
This paper explores the various features of the Apache USV series for efficient seafloor-level mapping. The CHCNAV hydrographic survey software is used for data recording and analysis. It provides results in the form of 3D models of the ground, contours and depth. (This story is brought to you by CHCNAV) Bathymetry is the study and mapping of the seabed or lake bed. It consists of obtaining measurements of the depth of the ocean or lakes and is equivalent to the mapping of the Earth’s topography. In general, only limited information is known about the seabed and lake beds. Existing maps... (read more)

Contribution of Hydrography towards Sustainable Water Management

FIG Commission 4: Hydrography
The 2019-2020 year has been a busy one with the Working Groups of Commission 4 focussing on representing FIG at a number of events and forum to gain insight to develops generally and also to deliver and present on the work of FIG. Through all its Working Group, Commission 4 has been actively involved in implementing its policy by working in close cooperation with relevant organisations and institutions. Altogether there are four (4) Working Groups for Commission 4 as listed below: WG 4.1 – Standards and Guidelines for Hydrography WG 4.2 – Blue Growth & UN Sustainable Development Goal 14...

Smart Surveyors: Developments and Trends from the FIG Working Week 2020

Some of the challenges demanding innovative surveying approaches and technologies are rapid urban growth, smart energy, cleaner mobility, and ‘land rights for all’. Sensing technologies, spatial data processing methods, and related approaches are already available. However, the question is how to use and improve them to become future proof, smart surveyors? Only ten years left to achieve the SDGs for a sustainable future. How can smart surveying contribute? To answer these questions, the papers of the FIG proceedings were analysed by the author-team.In this short article, we present the main trends distilled and the papers we refer to, represent these...

7 Questions about Hydrography and Its Relevance for Geomatics

The Perfect Combination of Science and Technology Applied to the Sea
According to NOAA (The U.S. National Oceanic and Atmospheric Administration), hydrography is the science that measures and describes the physical features of the navigable portion of the Earth's surface and adjoining coastal areas. It can be seen as an application area within the geospatial engineering discipline. We asked 7 questions to Laurent Kerléguer, the new director general of the French Hydrographic Office (Shom), to learn more about the world of hydrography. Chief weapons engineer Laurent Kerléguer was appointed director-general of Shom, the French hydrographic office, in July 2019. In this interview, GIM International asks him about the latest developments regarding the... (read more)

Immersive Geoscience to Be Key Topic at Virtual Geoscience Conference 2018

The Virtual Geoscience Conference (VGC) series is coming to Kingston, Canada, from 23-24 August 2018. The focus of the conference series is on innovative research and development in close-range remote sensing and computer visualisation applied to the geosciences. The series is all about innovative research and applications of geomatics, computer vision, graphics, gaming and virtual and augmented reality to a wide range of geoscience subfields, including geological mapping, geomorphology, geohazards, glaciology, volcanology, tunnelling and mining. This year’s meeting focus is on the theme of immersive geoscience and novel developments in virtual and augmented reality. The broad focus of the conference series allows geoscientists... (read more)

The Importance of Continuous Education

How Fugro Academy Advances the Company’s Business
It is now well over ten years since Fugro Academy opened its doors within Fugro as a focal point for learning and development for the company’s 10,000-plus employees, who specialise in providing geoinformation and asset integrity services to a global client base. So, what is Fugro Academy and how does it contribute to the ongoing education and professional development of the largely technical workforce? Andrew McNeill, global talent development manager at Fugro, explains more. Fugro Academy was established in late 2006. Around that time, Fugro was working in a very buoyant market, particularly for services related to oil and gas,... (read more)

Combining Hydrography and UAV Photogrammetry for Lake Volume Calculation

Creating a 3D Model for Volume Calculation with Boat and UAV
What is the best way to generate a high-precision 3D model to estimate the storage capacity of a lake that is surrounded by mountains? Rapid weather changes, low clouds and steep mountainsides demand a sensible approach with the right equipment. This article provides insights into the surveying process of a lake mapping project including the methods used to create a 3D model for the generation of a precise map with elevation lines. (By Benjamin Federmann, Benjamin Busse and Kim Schlüter, Germany) Situated at 848 metres above sea level in the Swiss Alps, created by an ancient rockslide and flanked by... (read more)
