Integrating UAS and Multibeam Echosounder Data

Creating a 3D Landscape Model of a Gravel Quarry in Germany
Knowing the volume of material present in a gravel quarry can make the difference between profit and loss. A gravel quarry in Hartheim am Rhein, southwest Germany, is partially covered by artificial lakes. To determine the volumes of the above-water gravel dumping grounds and to map the bottoms of the lakes, high-precision data captured by an unmanned aerial system (UAS) was combined with multibeam echosounder data obtained by boat. Read the full article for a description of acquisition of the two types of data, how they were integrated and the benefits for the mining company. A gravel quarry is associated with diggers, rough...

UAVs: The Deceptive Rise to Disruption in the Geospatial Industry

The period where exponential growth remains unnoticed following the inception of innovation is classified as ‘deception’. The year 1849 inaugurated the birth of the unmanned aerial vehicle (UAV or ‘drone’), producing a deceptive impact on the industry. Today, the use of consumer UAVs for data acquisition is quickly approaching its zenith, allowing for a broader scale of applications. (By Jonathan McCollin, University of the West Indies) The early use of consumer UAVs typically included videography. The move towards a photogrammetric approach occurred with the influx of mapping software, aimed at small-scale photogrammetry. These applications allowed for an autonomous, easy-to-use alternative...

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)

'Great Stories Start Here'

Point Clouds Everywhere at HxGN Live 2014
This year’s HxGN Live, Hexagon Metrology’s annual user conference, was once again held in Las Vegas, USA, from 2-6 June. Its maxim: ‘Great Stories Start Here’. From a geomatics point of view the event can be typified as ‘point clouds everywhere’. This report focuses on their creation by airborne Lidar, mobile mapping, trolleys and handhelds. Although Leica Geosystems, part of Hexagon, has been a prominent manufacturer of airborne Lidar systems for decades, in October 2013 it acquired Swedish Airborne Hydrograph AB (AHAB) – a small firm which has been specialised in bathymetric airborne Lidar for over 20 years. Today, AHAB... (read more)

Point Clouds (1)

The Functionalities of Processing Software
Whether based on Lidar, photogrammetry, radar, sonar or other remote sensors, systems for geodata acquisition create millions or even billions of 3D points. To be useful, the data needs to be organised, combined, georeferenced, measured and analysed, and that in turn requires software. This article first defines what point clouds are and identifies their sources. It then goes on to examine software functionalities such as visualisation and editing. The July 2014 edition of GIM International will be a themed issue covering collection and processing of point clouds and hence will include a selection of the many software packages currently available....

Pushing Lidar to the Limits

High-resolution Bathymetric Lidar from Slow-flying Aircraft
Airborne bathymetric Lidar is an ideal tool to study underwater features in the usually rather clear waters along the coast of Australia. Due to the remoteness of many of the continent’s coastlines, this is often the only economically viable option for large-scale bathymetric mapping at high resolution. A new toolkit consisting of two airborne Lidar systems flown on a small and slow-flying research motorglider was trialled in NW Western Australia. The same technology will be used over the next three years in the context of a comprehensive study of submerged archaeological landscapes of the so-called ’Sea Country’, more than 1,000km...

Looking Far beyond the Horizon: Interview with Hi-Target CEO Steven Xu

These are exciting times in the geomatics industry. Innovative solutions are being developed, integration is the main keyword and the big players are acquiring smaller companies that add a new dimension to their portfolio. Europe, Japan and North America are traditional strongholds of geomatics, but several very ambitious companies from China are doing their utmost to catch up with the frontrunners. At Intergeo 2015 in Stuttgart, Wim van Wegen took the opportunity to meet Steven Xu, CEO of Hi-Target, who was more than happy to share his thoughts and expectations with GIM International. Read the interview here. (By Wim van... (read more)
