UAS Demonstration during Intergeo

MAVinci will be offering exciting live UAS flight demonstrations next to the Hanover fair area at Intergeo from 9 to 11 October 2012. Visitors to the UAS demonstration can watch the complete mission workflow and give it a try themselves. The exact schedule for the demonstrations and more information about the comany's products are available at MAVinci’s booth, number C25 in hall 8. The MAVInci SIRIUS UAS is a ready-to-use system that allows everybody to obtain aerial images and orthofotos simply and compute three-dimensional Digital Elevation Models (DEMs). The complete system comprises the aircraft with autopilot, ground station for route planning... (read more)

UAS and Flooding

Monitoring Flooding and Assessing Damage in the Czech Republic
Heavy rainfall in late May and early June 2013 caused the Elbe, Vltava and Kamenice rivers to burst their banks in the Czech Republic. Among other areas, the Troja area of Prague and the villages of Hrensko and Nové Kopisty were severely flooded. Here, the author describes the experiences gained by the Czech company Geodis while using UAS technology to monitor and assess the impact of floods for the first time. Having proved that it can provide geodata quickly, cheaply and efficiently, UAS is now attracting significant interest from authorities. Figure 1, MD4-1000 from microdrones. Geodis is the producer of... (read more)

UAS Technology in Focus

A UAS intended for mapping, inspection or reconnaissance consists of a mix of elements including aircraft, a ground control station (GCS), on-board navigation sensors, a radio link for manual control of the aircraft, one or more geodata collection sensors and a wireless link for transmitting the data recorded by the geodata collection and navigation sensors to the GCS and PC, laptop or tablet (Figure 1). Usually the aircraft – whether a fixed wing or rotary wing – will be propelled by a battery-powered electric engine. However, the depletion of the battery charge is usually counted in minutes rather than hours.... (read more)

UAS Campus Survey Project

Students Capturing Spatial Information Needs
Texas A&M University-Corpus Christi, home to the largest geomatics undergraduate programme in Texas, USA, is currently undergoing a major university expansion. Both the main Island campus and the Momentum campus, which is a smaller developing campus, are undergoing extensive construction projects. The university’s Conrad Blucher Institute for Surveying and Science (CBI) was tasked with devising a comprehensive way to capture the spatial information needs related to the expansion. This effort is ongoing and is being conducted by students, providing them with a unique survey experience. The initial task was to perform a complete ground survey of all existing infrastructure at... (read more)

Experiences in UAS Photogrammetry

Quality Matters
UAS mapping is widely accepted as a new method for acquiring spatial image data. The main business opportunities clearly lie in projects which are too small to be of interest for aircraft and helicopter platforms and too big for field mapping. Nevertheless, performing UAS operations profitably and with high-quality results is quite demanding. At the end of the day, the paying end customer is not really interested in whether the data was produced using UAS or more traditional methods; data quality is all that matters. This article focuses on UAS mapping productivity topics, shedding light on the practical challenges of... (read more)

UAS Applications Are Ubiquitous

Unmanned aerial systems (UASs) include imaging systems and/or airborne Lidar systems on an ever-increasing number of variously sized, remotely piloted fixed-wing or multi-propeller systems – the latter being able to hover and take-off vertically – as well as hybrid systems. In 'GIM International' and other surveying and mapping literature, there have been many articles describing the use of UASs, new developments and precautions that need to be taken to achieve satisfactory results. This article explores how UAS applications have become ubiquitous. (By John Trinder and Yincai Zhou, The University of New South Wales, Australia) In many countries, small UAS operations...

UAS in Farming

A Pilot Project in Cuba
The popularity of unmanned aerial systems (UAS) is on the rise in many countries for a multitude of applications. In one such development, the UAS is rapidly becoming a tool for crop monitoring and management, which is essential for food security. GeoCuba has been successfully testing UAS technology for farming purposes. Here, the authors describe a pilot project conducted in Cuba in co-operation with the Russian firm Uniintex-Ginus. Figure 1, Preparing the Delta-Photo system for flight   Cuba covers a land area of nearly 110,000 square kilometres, of which nearly two-thirds is cultivated. With an annual sugar production of 5...

UAS in the Andes

Determining Volume Changes of the Chuquicamata Open Pit Mine
In mining, the determination of volume changes over time is an important surveying task. However, harsh environments can make gathering precise and up-to-date geodata challenging. Traditional land surveying and terrestrial laser scanning are faced with many hurdles when used in remote open pit mines. UAS provides an alternative without compromising accuracy. Here, the authors present UAS surveys carried out high in the Andes. The gathering of information in open-pit mines is associated with many risks. If security protocols are not strictly followed, heavy equipment may injure surveyors operating on site. In addition, digging ore produces dust, noise and other unfavourable... (read more)

UAS Potential in Archaeology

Archaeology entails the recording of the physical remains left by past generations. Traditionally, archaeological exploration has been by excavation. Other survey techniques have recently gained importance in recording remains that are visible above the ground. Examples include prehistoric fields, settlements and burial remains in upland areas, or industrial landscapes, buildings and standing monuments such as stone circles in other areas. It is more than worthwhile to explore the application of unmanned airborne systems (UASs) in archaeology. In the past most recording was done with tape and a 1m planning frame, while a theodolite was a luxury. More recently total stations, GNSS receivers, terrestrial... (read more)
