Contributing Editor Tony Murfin is on vacation this month. In place of his column, we bring you an advance look at an important UAV show as applied to surveying and mapping, and a story about drone use in surveillance.
In the zone
Legal issues, international market analyses and best practices will take center stage at the Interaerial Solutions Expo (IASEXPO), which will take place Sept. 26–28 in conjunction with Intergeo 2017 in Berlin, Germany.
At IASEXPO, the international UAV sector will be demonstrating the potential for civil and commercial UAV applications. IASEXPO will consist of an exhibition, forum and the FlightZone for UAV demonstrations. About 150 providers from 25 countries are expected to represent the young drone market at the IASEXPO.
IASEXPO’s practical forum will cover the latest topics with renowned experts. Visitors don’t have to walk far to switch between market overviews and expert presentations. The aim is to efficiently combine the trade fair and talks.

Regulations. As Germany’s drone regulations come into force this year, the legal aspects of using and operating UAVs is a key focus of the practical forum. Multicopters and drones weighing more than two kilograms can now only be flown in Germany by someone who holds a “drone driving license.” Pilots will be able to take the drone license test at the trade fair.
Frank Wichert from project management company procow will detail the requirements and reveal the precise procedure that pilots must follow. Speaker Ulrich Dieckert is a lawyer and expert on the approval process; he specializes in exceptions to operating bans that hinder drone work.
Market prospects. Kay Wackwitz, CEO of Drone Industry Insights, will present economic analyses of application opportunities and limits for UAVs, and discuss market developments and collaborations.
UAV Issue Manager Ralf Heidger from German traffic control (DFS) will discuss how DFS tackles the challenge of drones in the air space and tracking them within the air-traffic-management system.
Best practices. First-hand reports will provid examples of best practices in using drones for surveying and inspecting buildings and industrial complexes. Friedrich Wilhelm Bauer from Hannover University of Applied Sciences and Arts will highlight use of thermal-imaging technology for inspections. Benjamin Federmann from Aibotix-Leica will discuss the economic benefits of using drones in surveying and construction.
The German Association of Copter Pilots will weigh the question of whether to “make or buy” needed drones and services. Answers come from success stories in niche segments such as 3D modeling and smart framing. Maik Neuser from Westnetz and Carlo Zgraggen from Aeroscout will discuss inspections in the energy sector.
Other topics will be the use of drones in agriculture, forestry and disaster relief. Antoine Cottin from Carbomap and Bobby Vick from Precisionmapper will speak to the practical forum on drones used for surveying forests.
Drones on patrol
UAVs will soon be a common sight over border zones, crime hotspots and city streets in South Africa, as public safety and security officials and police departments discover the cost saving and efficiencies offered by drone patrol “armies,” according to Airborne Drones, a South African-based manufacturer of enterprise-grade drones.

Drones provide a solution to the limitations of other surveillance methods such as GPS tracking, CCTV camera observation, biometric surveillance and ground patrols. Aerial surveillance is increasingly being harnessed for security monitoring — traditionally, with costly helicopters. Drone surveillance present an faster and cheaper method of data collection.
Specialized security drones can enter narrow and confined spaces, produce minimal noise, and can be equipped with night-vision cameras and thermal sensors, allowing them to provide imagery that the human eye is unable to detect. In addition, UAVs can quickly cover large and difficult-to-reach areas, reducing staff numbers and costs, and don’t require much space for operators.
Autonomous, long-range security drones are at the vanguard of new policing methods, accoring to Airborne Drones. “Offering live video feeds to ground control stations, these drones can range autonomously over pre-programmed flight paths for extended periods of time, allowing for ongoing routine patrols across wide areas such as borders, maritime regions and high security installations.
Should an incident be detected, ground crews can then follow objects or intruders from a safe distance, providing visual support to safety and security teams. UAVs can provide detailed visual documentation of sites, enabling effective analysis, risk management and security planning.”
Around the world. Numerous countries are rolling out security drones to support public safety and defense initiatives”, says Airborne Drones. Israel has long harnessed advanced drones for military surveillance, and recently sold a fleet of “spy drones” to the Irish army.
The U.S. FBI has used drones for surveillance and tracking for several years. In Australia, the new $50 million Defence Cooperative Research Centre will develop long-range drones, automated vehicles and robots to help Australian soldiers fight the wars of the future. India is looking to military-grade UAVs for maritime and other surveillance and intelligence gathering.
In June, Brazil’s São Paulo became the first Latin American city to use drones for public security surveillance, and in July, Hamburg, Germany, deployed surveillance drones for the estimated 100,000 demonstrators at the G20 summit. In Australia’s New South Wales, the authorities are using helicopter and drone surveillance along the coast to protect holiday-goers from rip currents and sharks.
UAVs are also instrumental in managing transport infrastructure safety and security and event security, from event security infrastructure to spectator and crowd control and safety, to overall health and safety planning.
