Use of civilian drones in Germany

A study by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has now revealed that there is clear approval in Germany for the use of civilian drones in civil protection, rescue missions and research work. However, flights for advertising, leisure and parcel delivery purposes are still viewed negatively by at least half of those questioned. .

“Regardless of gender or age, the term ‘drone’ is known to almost everyone, but often retains negative connotations,” explains study leader Maria Stolz of the DLR Institute of Flight Guidance in Braunschweig. “Experience with drones remains rare and is more usually passive, rather than active. There is still relatively little information available to the public on this topic.” Only around 40 percent of those surveyed said that they had ever seen or heard a drone, while just 10 percent had ever flown a drone themselves. The attitude towards civilian drones depends on gender and age, among other factors. Those expressing an interest in this modern technology were predominantly young males. “We were also interested to see whether the respondents changed their attitude over the course of the interview,” says Stolz. “There was a slight shift towards a more positive view.

The researchers were able to establish that there is currently clear approval for the use of drones in civil protection, rescue missions and research work. Around two-thirds of respondents agreed fully or partially with the use of drones in order to ascertain the situation in often inaccessible disaster areas, or to support the police and fire brigade in lifesaving missions by providing situational information or location data. www.dlr.de

UAV can help avocado growers by detecting asymptomatic pathogen

Remote imaging can effectively detect a pathogen that endangers the $100 milliona- year Florida avocado industry – even before the trees show symptoms Yiannis Ampatzidis, an assistant professor of agricultural and biological engineering at the UF Institute of Food and Agricultural Sciences, led recently published research that shows that multispectral cameras can detect laurel wilt on avocado trees. The approach costs less than manually trying to detect the laurel wilt pathogen, Ampatzidis said, though UF/IFAS researchers don’t know yet the cost differential.

Multispectral cameras can capture data within specific wavelengths across the electromagnetic spectrum, said Ampatzidis, who specializes in precision agriculture. Humans can only see very small areas of the spectrum. http://southeastagnet.com

Management of complex forest environments by UAS

Unmanned aircraft systems (UAS) offer the potential to provide timely and accurate reference data in forests and other complex environments for research and management applications, according to researchers at the University of New Hampshire.

Researchers, Benjamin Fraser and Russell Congalton with the UNH Department of Natural Resources conducted a study on about 1,300 acres of New England forest to evaluate the effectiveness of UAS to collect accurate map reference data. They noted that while advancements in remote sensing and computer science technologies have provided the ability to map increasingly complex environments, the accuracy of thematic maps based on this data must be assessed against reliable reference data, which can be difficult to obtain because of time and cost restraints.

Thematic mapping relies on imagery from remote sensing to label objects and features in defined groups. It also provides information on land use and cover, which helps identify “both natural and artificial patterns and increase our ability to make informed decisions,” according to the paper. Aerial imagery was collected during June and July 2017 using fixed-wing UAS equipped with a sensor optimized for drone applications.

Validating data quality is a necessary step in the decision-making process when using conclusions drawn from remote sensing, the researchers said, adding that in the past, this has been difficult and costly to accomplish. However, the availability of UAS as low-cost, flexible platforms capable of generating on-demand, highresolution images changes this.

Taranis launches automated crop emergence and stand count solution

Taranis has announced the launch of its new solution that calculates and monitors the planting of seeds. It is the first platform to offer farmers and agronomists a scalable answer to plot management strategy.

As part of its solution, Taranis flies a drone or aircraft over a field using the company’s patented AI2 proprietary pod, which captures hundreds of sub-millimeter images on a single field, or thousands of images in a given flight. Each image is scrutinized by Taranis’ deep learning engine to quickly identify and count each emerging plant. A second set of algorithms is run to calculate the spacing, density and plant characteristics of each row, while a third set of analysis creates the clear visualization of emergence in the form of a heat map. With available heat maps and easy-to-read reports, customers can review their fields quickly to make timely management decisions. www.taranis-emergence.com
