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)

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 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 Experiences in Africa

Heat, Dust and Distrustful Locals
When conducting surveys in countries near the equator, environmental conditions can be harsh. Heat, dust and humidity may disrupt sensitive equipment, while distrustful locals may obstruct the undertaking. Read on to learn about the experiences during a UAS survey on the savannah of Benin, West Africa. Germany-based Spectair Group offers multiple aerial services including video recordings from unusual perspectives, support services to police, firefighters and rescue teams, inspection of industrial plants, solar roofs and buildings, and mapping and surveying services. In July 2014, the company was commissioned to conduct a UAS survey to produce orthoimages and 3D landscape models of a... (read more)

UAS for Mapping

A Product Survey on Systems and Features
In recent years, unmanned aerial systems (UAS) have attracted tremendous attention from surveyors and other geodata collectors all around the world. Nowadays, UAS equipped with GNSS, IMU and RGB, NIR or TIR cameras and possibly Lidar have evolved into high-potential surveying devices which have now definitely passed the stage of ‘toys for boys’. This article focuses on UAS for mapping and 3D modelling and provides a detailed survey in tabular format on the features of the prevailing systems, both fixed wings and multicopters, available on the market today An unmanned aerial system (UAS) is an aircraft which flies without a...

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)

What is a UAS?

In the past an aircraft was just called an ‘aircraft’, without the qualifiers ‘manned’ or ‘unmanned’ since the ‘manned’ version was the only option. Of course, the unmanned ones have been around nearly as long as the aircraft designed for travel or transportation, but they were previously flown by the military – the warlords called them ‘drones’ – or model airplane enthusiasts. With the emergence of unmanned aerial systems (UASs) came the need to distinguish ‘manned’ from ‘unmanned’, so today we have UASs versus MASs (Multiagent Systems). (By Mathias Lemmens, senior editor, GIM International) Are UASs here to stay or... (read more)

Fixed-wing UAS

Monitoring a Nuclear Power Plant Construction Site
Monitoring a nuclear power plant construction site requires regular collection of site data; even up to weekly coverage may be necessary. Conventional photogrammetry and land surveying are often too costly. The author shows that UAS technology based on a fixed-wing aeroplane enables weekly coverage of a 150-hectare construction site. The orthomosaics, digital elevation models, maps and 3D models generated from the imagery support site monitoring beyond expectations, while new applications are being found all the time. Hinkley Point in Somerset, UK, is one of eight nuclear power stations owned and operated by EDF, a wholly owned subsidiary of France-based EDF... (read more)

Monitoring Vulcanoes with UAS

Testing the Suitability of Thermal Infrared Sensors
Insight into signs that prelude volcanic eruptions is key for protecting the lives, livestock and property of those living in the vicinity of a volcano. One key indicator is temperature rise. Using Mount Etna as a test site, the authors show that a UAS equipped with a thermal infrared sensor generates data similar to temperature data acquired by ground-based stations while avoiding safety risks for volcanologists.   Data from Earth observation satellites with high temporal resolution can be used to monitor volcanic eruptions on an intraday basis when combined with images from satellites with a high GSD but low repetition...
