Recent Developments in Airborne Lidar

Multispectral Laser Scanning, Single-photon Lidar, Hybrid Sensors and UAVs
The arrival of airborne Lidar, also referred to as airborne laser scanning (ALS), has revolutionized area-wide 3D data acquisition of topography, bathymetry, vegetation, buildings and infrastructure. This article presents an overview of the progress made since then in both sensor and aircraft technology. On top of that, it highlights how ongoing miniaturization has recently enabled the application of Lidar on unmanned aerial vehicles (UAV), resulting in ultra-high-resolution 3D point clouds with centimetre precision. From Single to Multiple Pulses in the Air Current trends include a steady increase of the measurement rate, achievements in full waveform processing, the spread of multispectral... (read more)

Crossrail Monitoring - Delivering the three Rs

The decision to take monitoring in-house has allowed Morgan Sindall to create a tailor-made solution that delivers the three Rs sought by Crossrail, Network Rail, and Docklands Light Railway on the C350 Pudding Mill Lane contract. In 2018 Crossrail services are due to commence through central London. The £15bn project will pass through 37 stations and run 118 km (73 miles) from Maidenhead and Heathrow in the west to Shenfield and Abbey Wood in the east. The project’s C350 Pudding Mill Lane contract, won by Morgan Sindall plc, is worth in the region of £100 million and will link the... (read more)

Looking to the Future of Ordnance Survey - Interview with Peter Hedlund

Peter Hedlund leads an OS team that helps National Mapping and Cadastral Agencies and governments around the world develop and grow their geospatial capabilities. Prior to joining OS as Managing Director, Peter was Regional Director of Middle East and Africa for Trimble, where he produced and implemented strategies that grew Trimble’s international business across continents. Geomatics World: What attracted you to join OS and how is your past experience relevant to the position? Peter Hedlund: Ordnance Survey (OS) is well-known and respected the world over. It has an excellent reputation. Geospatial data underpins an increasing number of people, businesses and... (read more)

Powering the Future with Data and BIM - Digital Construction Week 2018

Digital Construction Week 2018 returned to Excel in October as an exhibition, with a main stage for paid conference sessions and several ‘theatres’ within the exhibition space. This article gives a taste of what was on offer over the two days. Real-time Asset Management The first day started with a 15-minute presentation from the Enable My team entitled ‘The Art of Raw Data’. This was all about using camera feeds from the front of trains to build up and maintain a real-time asset record. Apparently, cameras have been deployed for some time, but the data has not been used for... (read more)

Geoinformation Software as a Service

From Licensing to Subscription
Accurate geoinformation about urban areas, public buildings or historical sites is in great demand. It has become astonishingly easy to capture these scenes through cameras or laser scanning or to acquire open data from a diversity of sources. Professionals without a surveying background can do the job, but such professionals require reliable, robust, easy-to-use and affordable processing tools. Today, cloud computing can meet that need, enabling users to work with software packages running on remote servers on either a pay-per-use or a subscription basis. This article presents a cloud computing service dedicated to geoinformation software. Storing data in the cloud... (read more)

User-friendly Remote Sensing Data Infrastructure in France

New Services Will Stimulate Market Growth
Over the past decade, Geosud has contributed to successfully mitigating the various obstacles to the operational use of satellite imagery for environmental management and territorial development. Geosud’s role in the project will soon come to an end but the services will continue, embedded in an even better infrastructure: Dinamis. As of next year, Dinamis will provide satellite images of land, sea, air or underground, and even online image processing, for organizations related to the public sector in France. As you approach the Maison de la Télédétection in Montpellier, France, the first sight that greets you is a 5.5m-tall receiving station... (read more)

Digitizing Reality: Automated 3D Point Cloud Data Processing Using AI

Intelligent Point Clouds
Instruments for digitizing the 3D real environment are becoming smaller, more lightweight, lower-cost and more robust. Accordingly, they are finding increasingly widespread usage, not only on surveying tripods for the highest accuracy, but also on mobile platforms such as autonomous vehicles, drones, helicopters, aircraft, robotic vacuum cleaners, trains, mobile phones, satellites and Martian rovers. Lidar uses laser scanning, while photogrammetry records images from one or more cameras which may be moving. Each laser scan records tens of millions of data point positions and colours in a point cloud, and hundreds of such point clouds may be combined. This article discusses... (read more)

Drones a Vital Tool in Climate Change Research

Drones are playing a crucial role in vital work to better understand the effects of climate change in the Arctic. Dr Joseph Cook, a glaciologist at the University of Sheffield, is conducting major research projects in Greenland, exploring the impact of global warming on glacier and ice-sheet dynamics. To help these studies, Dr Cook and his team are harnessing the power of drones, including a DJI Mavic Pro. As part of these investigations, Dr Cook has turned to UAV expert Heliguy for equipment and industry advice. Heliguy recently interviewed Dr Cook to find out more about his work in the Arctic and...

Enhancing Virtual Singapore with BIM Data

Drawing on leading science and design principles, Singapore combines characteristics from both the natural and man-made environments in a way that creates a sense of harmony and balance, also giving the city its unique feel and identity. This is best observed from any number of skyline terrace bars in downtown Singapore, but especially during the sunset hours – the transition between day and night as light reflects across the Marina Bay, and all the shiny edges and surfaces, showcase a real ‘smart city’ in motion. It is clear to see that Singapore’s status, as an often-cited global exemplar ‘garden city’,... (read more)
