From above to below

It seemed an unsolvable challenge: how to add hydrographic survey capabilities to a helicopter without making it impossible to fly. Martin Pfennigbauer and Kohei Wakamatsu explain how two companies worked to make the impossible possible.

Nakanihon Air Service Co Ltd is one of the largest general aviation companies in Japan. It operates approximately 70 aircrafts, offering transport, emergency medical services, and aircraft maintenance, repair and modification services, as well as airborne research and survey.

In 2007, the company started airborne LiDAR works using a helicopter and a RIEGL LMS-Q560 with JIRCO’s high density medium-format digital camera part of a system called Sakura (‘cherry blossoms’) – approximately 70% of land in Japan is mountainous, so a helicopter platform is preferable.

The system gained wide acceptance in the market for its capture of high-density 3D point clouds, especially in dense vegetation.

Since then, the company has steadily upgraded the Sakura, with the Sakura-IV offering a pulse repetition rate of 400 kHz thanks to adoption of the RIEGL LMS-Q680i and a multiple field of view, medium-format camera-configuration that offers up to five different camera angles at the same time. It can now achieve more than 30 points per square metre of topographic point clouds simultaneously with multiple digital images, including approximately 5cm ground sample distance (GSD) nadir images, on a daily basis.

Novel LiDAR Data Improves Our Understanding of Tropical Forests

Dr. Kim Calders and his team have just completed 2 months of field work in Australian tropical forests collecting both terrestrial and UAS lidar data to support a novel lidar data fusion methodology.

Forest ecosystems contain more biomass than any other ecosystem. However, estimating biomass without cutting down trees is difficult. Traditional methods of estimating aboveground biomass (ABG) are based on correlations between destructive estimates of volume and diameter and/or height, which can be measured more easily in the field.

However, harvesting trees is expensive, often impractical and undesirable. 3D-FOREST, a three-year project funded by the Belgian Federal Science Policy Office led by Dr. Kim Calders and Prof. Hans Verbeeck from Ghent University, partnering with Dr. Harm Bartholomeus and Prof. Martin Herold from Wageningen University, aims at providing novel lidar in-situ 3D forest structure and biomass estimates to validate large-scale air/spaceborne biomass products. Co-incident LiDAR data from different platforms was collected to quantify aboveground biomass and forest structure in five tropical sites in Australia during a two-month fieldwork campaign in the dry season.

Assessing the Potential

Understanding stream channel and floodplain morphology is critical for a number of efforts—from hydraulic modeling and stream-restoration design to aquatic habitat assessment. These applications require description of conditions both inside the channels and in the adjacent riparian zones. Gathering these data has typically relied on individuals on the ground or in boats taking measurements in small areas, or manned remote sensing flights that are designed to cover much larger expanses.

The advent of small unmanned aerial systems (sUAS), combined with innovations in sensor technology, is changing the equation for surveyors. These advancements give surveyors the power to do detailed elevation mapping over larger swaths than conventional ground/water-based surveys while providing greater detail at a potentially lower cost than manned flights.

Quantum Spatial Inc. (QSI) recently teamed with RIEGL to evaluate use of interchangeable bathymetric and terrestrial laser scanning sensors that could be used on sUAS platforms to support riverine mapping applications. QSI tested RIEGL’s new bathymetric depth finder (BDF-1) and the RIEGL VUX-SYS laser scanning system in three distinct riverine environments. The sUAS-based sensors were evaluated for their potential to efficiently collect channel geometry in areas where the water was not easily accessed or it was too dangerous to use ground- or water-based methods.

Proving the Rescue Potential of Multi-sensor UAVs

When disaster strikes, the courage and experience of rescue task forces is put to the test. They face heading into the unknown every time they enter a terrain during a rescue mission. Efforts to implement the latest technological tools, such as UAVs, to support their work are aimed at providing safer working conditions for rescue teams and speeding up search activities to improve the efficiency of the entire rescue mission. UAV reconnaissance is considered a very powerful way of overcoming the potentially dangerous lack of information in affected areas.

Specially equipped unmanned aerial vehicles (UAVs or ‘drones’) have in the past been proposed for firefighting, for search missions, for delivery of rescue kits, and many other impressive tasks. There are high expectations of the use of drones for this type of work, and for obvious reasons: they can go where it would be too hazardous or even impossible for manned aircraft to go. This is one of the major arguments for UAV utilisation.

An experiment was carried out within the framework of the Austrian research project called ‘SecuRescue’ and following emergency scenario was imagined for a test setup: a disaster, caused by natural forces or technical failure, hits an urbanised and partly industrial area. The test focused on how to provide essential access information to first responders as quickly as possible, and ideally in real time.

The RIEGL VUX-1UAV LiDAR System was used for acquiring the precisely updated topographic information and the data has been collected by RIEGL RiCOPTER-M.

Comparing Lidar and Photogrammetric Point Clouds

Airborne Lidar and photogrammetry are both viable methods for capturing point clouds for 3D modelling of man-made hard structures. Although both methods produce point clouds, the manner of capturing data differs in many ways, resulting in point clouds with differing characteristics. In this article, the author evaluates Lidar and photogrammetric point clouds captured from unmanned airborne systems for inspecting a flood control structure.

The New Orleans District of the U.S. Army Corps of Engineers (USACE) has been using small unmanned airborne systems (UASs) for land surveying, environmental monitoring, structural inspections and other applications. However, the characteristics of one UAS platform may greatly differ from those of another, and the same is true for the large variety of sensors. To identify key differences between the point clouds produced by UAS Lidar and UAS photogrammetry, a comparison has been conducted using a flood control structure as test site.

The RIEGL VUX-1UAV LiDAR System was used for land surveying, environmental monitoring, structural inspections and the data has been collected by RIEGL RiCOPTER.

UAS-borne Lidar for Mapping Complex Terrain and Vegetation Structure

The development of lightweight, survey-grade Lidar sensors has made it possible to equip unmanned aerial systems (UASs) with very precise laser scanners, thus opening up new possibilities in the domain of close-range 3D mapping. To test the capabilities of UAS-borne laser scanning, a flight experiment was conducted using the RIEGL VUX full-waveform scanner mounted on a RIEGL RiCOPTER UAS platform. In the experiment, both the topography and the vegetation structure of an alluvial forest along the River Pielach in Lower Austria were captured. The resulting point cloud has a density of more than 1,500 points per square metre and an accuracy of better than 2cm.

The Neubacher Au is a Natura2000 conservation area near the confluence of the Pielach and Danube rivers. It is a highly dynamic landscape due to periodical inundation during flood peaks. The fluvial topography includes pristine channels, side channels and oxbow lakes. This topography is perpetually changing, as is the vegetation structure. As a retreat area for aquatic and terrestrial habitats, alluvial forests are of high ecological value. Mapping these sensitive areas with traditional terrestrial or airborne techniques is challenging due to the high complexity of the terrain and the vegetation.

The recent advance of survey-grade Lidar sensors with a weight of less than 10kg offers new perspectives for 3D mapping of complex natural landscapes in high resolution. To test the potential of UAS-borne laser scanning, a flight experiment was conducted using the RIEGL VUX sensor mounted on a RIEGL RiCOPTER UAS.

3D Laser Scanning for Heritage - Advice and Guidance on the Use of Laser Scanning in Archaeology and Architecture

"3D Laser Scanning for Heritage" is a guidance, produced by Historic England, that provide the necessary information to use laser scanning appropriately and successfully for heritage projects. It is hoped that from the advice given on how the method works and when it should be used, archaeologists, conservators and other cultural heritage professionals unfamiliar with the approach can make the best possible use of this now highly developed technique.

Laser scanning is a very capable and flexible technique but in many cases no single survey tool offers a complete solution, and other methods of three-dimensional (3D) data capture may be required.

Some of the given examples have been carried out by using RIEGL Waveform-LiDAR technology und show how RIEGL laser scanners and systems can be used for surveying, managing and caring for historic buildings and their settings as well as for investigating heritage.

Geologist will upgrade monitoring of Greenland glacier critical to sea-level rise

University of Kansas in cooperation with the U.S. Army Corps of Engineers Cold Regions Research and Engineering Laboratory (CRREL) and supported by the Heising-Simons Foundation will install a second ATLAS System at Helmein Glacier in Greenland. The first system, that is situated on the south side of Helheim Glacier - with a RIEGL VZ-6000 Terrestrial Laser Scanner operating at 1064 um wavelength as its backbone -  already delivers valuable data to measure how the glacier is moving horizontally and vertically at the same time.

Helheim Glacier discharges a lot of ice each year and the scientists are very interested in understanding what controls its behavior. The second ATLAS (Autonomous Terrestrial Laser Scanning system) will be installed opposite of the first one to monitor rates of ice loss on the tidewater glacier undergoing large-scale changes due to global climate change. This will enable glaciologists to better predict future sea level rise – a topic of increasing importance to low-lying coastal communities.

All in a Day’s Work

Can laser scanning from UAV and car replace total station and GPS surveys of roads?

A project in Croatia tried to find out: Developments in the field of laser scanners and laser scanning systems have increased in the past few years. Physical size has decreased while performance has increased. The number of laser pulses per second has reached a million and the measurement distance is in the hundreds of metres.

RIEGL has implemented these and other features in a variety of compact, powerful, and precise scanners. Attached IMU/GNSS units, governing control units and optional cameras collect/record a multitude of additional properties during each scan. Due to the straightforward attachment system, a quick and easy installation is possible onto helicopters, vehicles and even UAVs – the modern tools of choice to accurately surveying road infrastructure in the highest possible quality.

The system’s flexibility became an important aspect in a project of RiCOPTER UAV GmbH, which was executed in December last year on behalf of Geoprojekt LLC, one of the major geodetic companies in Croatia.

The company was interested in a practical demonstration of the benefits and advantages of laser scanning for their fields of operation. The mission was to acquire both mobile and aerial laser scan data of an area of 2km x 1.5km that had previously been surveyed conventionally using DGPS and total stations. The data acquisition was conducted using the RIEGL VUX-SYS laser scanning system. For mobile data acquisition, the system was used with the RIEGL VMQ-1HA mounted on a car wiwhile for the aerial data acquisition the RiCOPTER, RIEGL’s unmanned octocopter, was used as platform for carrying the VUX-SYS.

Merging Terrestrial and Hydrographic Scanning

Back in the late 1980’s John F. Sawyer saw the need for a surveying services company that could provide accurate hydrographic surveying and quantity calculations. Mr. Sawyer had a background in dredging and in 1989 Arc Surveying and Mapping (Arc) was born. The company is family – owned and operated with three brothers running the day – to – day operations.

Today Arc has a wide variety of underwater survey systems including multibeam and singlebeam sonar, Blueview 3D sonar and a magnetometer. They use a wide variety of software to post process the data including RiSCAN Pro and Hypack for the hydrographic data. Merging terrestrial and hydrographic data was acquired by using RIEGL VZ-400 3D Terrestrial Laser Scanner.

Der Superscanner der Polizei ist gelandet!

Eigentlich für den Einsatz im Helikopter gebaut, setzt die Kantonspolizei Zürich den VP-1 mit eingebautem VUX-1 Scanner nun auch erfolgreich für mobile Datenaufnahme am Boden ein.

In der Luft kommt das Laserscanning-System zum Einsatz, wenn Schadensplätze oder Ereignisse auf großer Fläche vermessen werden müssen, z.B. bei Zugsunglücken, Flugzeugabstürzen, etc.

Nicht immer aber ist ein Helikoptereinsatz möglich - in einem Tunnel z.B. kann dieser nicht eingesetzt werden. Dafür wird das System nun auch auf einem Auto eingesetzt und liefert bei gefahrenen Geschwindigkeiten von 30 km/h erstklassige Daten. Für eine Übersicht ohne viele Details kann die Datenaufnahme sogar bei Geschwindigkeiten bis zu 80 km/h erfolgen.

SKUR: Change Data Tailored to the End User

SKUR CEO Adam Cohen describes their software solution as a tool for "visualizing variance." At the most basic level, that means it  takes a design model and a current point cloud of the same asset, and generates a visual representation of the differences between the two. It uses cloud computing and advanced algorithms to do it in a negligible amount of time.

When the team demoed the software for me, they pulled up one of these visual representations. It depicted a room with three pillars. Most of the room was green, meaning that the as-built scan (gathered with a RIEGL scanner) matched the design model perfectly. One pillar was yellow, which meant that it had shifted a little bit, and another was red, which meant that it had shifted a lot.

On this basic technology, SKUR has built a tool that could be essential to the construction and facilities management industries.

RIEGL support SKUR as a development partner.

Bathymetry of Lake Constance

In 2014 the by far biggest German lake has been newly surveyed. The transnational project is funded by the European Union and delivers a detailed 3D-model of the lakefloor. The German project name is »Tiefenschärfe – Hochauflösende Vermessung Bodensee «, which in English roughly means: high-resolution survey of Lake Constance. The German term »Tiefenschärfe« (in optics and photography: depth of field) plays with the meanings of »Tiefe« (depth) and »Schärfe« (sharpness). The result of the survey shall be a clear and sharp image of the deep lake-floor. At present the LiDAR and multibeam data are still processed, but first results are presented in this article.

Data was acquired with support of AHM AirborneHydroMapping GmbH ( www.ahm.co.at ) using a RIEGL VQ-820-G hydrographic scanner.
