Intergeo Press Conference: Looking Back and Forward

In line with tradition, this year’s Intergeo press conference once again took place at noon on Wednesday. Despite the press room being a little difficult to find, members of the international geomatics press came together to hear the views of the event’s key stakeholders. The press conference, which was based around the central theme of ‘Digital World – Connected World’, not only reflected on the past 20 years of Intergeo, but also looked ahead to the future of the geomatics industry. (By Wim van Wegen, editorial manager, GIM International) The speakers were Prof Dr-Ing Karl Friedrich Thöne, president of the... (read more)

Low-cost GPS Sensors for Deformation Monitoring

Monitoring Deformations on a Glacier with Wireless Sensor Networks
Deformation monitoring of glaciers is of great value to scientists with an interest in climate change. Due to the slow movements of glaciers, a semi-permanent deformation system is the best method to monitor the changes. Using low-cost GPS receivers that work in a wireless sensor network makes such a set-up feasible. Glaciers are large bodies of ice moving slowly downhill under the forces of gravity. On the way down, the ice deforms, creates crevasses, speeds up and slows down. The process involves huge forces. Monitoring these movements is of great scientific interest, but due to the slow dynamics a semi-permanent... (read more)

Five Years of ‘Works When You Do’

Geomax
GeoMax Zenith 10&20 RTK GNSS – a flexible system with all communication devices integrated. When GeoMax arrived on the international stage in 2008, many experts doubted whether there was room in the surveying market for another brand alongside the established big players. Now, five years and a major worldwide economic crisis later, GeoMax has secured its place in the sector. From the beginning, the company’s aim was to serve the fast-growing mid-range segment. In line with its ‘works when you do’ concept, GeoMax’s products are focused on offering an attractive price-to-performance ratio. This five-year milestone represents the ideal opportunity to...

Fast Survey of a High-speed Railway Line

Surveying a 140km Corridor with a UAV for Railway Planning
Large corridor surveys, such as roads and railroads, used to be the domain of airborne photogrammetry or Lidar using conventional aircraft. In Turkey, it has been demonstrated how a 140km corridor can be efficiently surveyed using a fixed-wing UAV. Streamlined operations and a large number of ground control points are essential to achieve results suitable for railway planning purposes. The Turkish government is planning the construction of a large, nationwide high-speed rail network. A high-speed rail connection between the cities Ankara and İzmir is currently in the planning phase. Thanks to an intended speed of 250km/h, the journey between the... (read more)

3D UAS Mapping of a Copper Mine

Capturing Geospatial Data under Challenging Circumstances
In May 2018, the Erdenet Mine in the north of Mongolia was mapped in just three days. The open pit mine measures 5km by 2km and has an elevation difference of 200 metres. The dusty and complex circumstances called for the use of an unmanned aerial system (UAS). Despite the strong wind and extremely variable weather conditions, a single UAS quickly captured the geospatial output necessary for the management of one of Asia’s – and the world’s – largest copper mines, as described in this article. The big data gathered and processed by the Czech firm UpVision provided a perfect... (read more)

Agricultural Robots and Drones to Become a 45 Billion Dollar Industry by 2038

Robotic technology is quietly transforming the world of agriculture. A report by IDTexchEx describes how this market will plausibly grow to become a US $45 billion industry by 2038. It also demonstrates how diverse this emerging industry is in terms of forms, functions and fortunes. The report, titled ‘Agricultural Robots and Drones 2018-2038: Technologies, Markets, Players’, develops a detailed roadmap of how robotic technology will enter into different aspects of agriculture and how it will change the way farming is done. It provides 20-year forecasts for 16 categories including static milking robots, mobile dairy farm robotics, autonomous agricultural small robots... (read more)

Unmanned Aerial Systems for Cadastral Applications

Testing a Fit-for-purpose Land Administration Approach in Indonesia
In recent decades, imagery-based methods have gained legitimacy in the domain of cadastral data creation. Contemporary experiences from Rwanda, Ethiopia and Lesotho, along with older activities from Thailand, already demonstrate the potential of conventional aerial imagery and high-resolution satellite imagery. More recently, unmanned aerial systems (UASs) have received increasing interest in the field of land administration. Already documented trials and demonstrations are evident for Albania, Namibia and Rwanda. The exploratory work continues; results from trials undertaken in Indonesia are presented here with a view to identifying the opportunities and challenges for embedding the technologies in a fit-for-purpose way into the...

Comparing Lidar and Photogrammetric Point Clouds

Point Clouds for Inspecting Flood Control Structures
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... (read more)

UAVs as Tools for Urban Planning in Uruguay

Photogrammetric Surveys of Irregular Settlements
Irregular settlements, also known as villas or favelas, present a big challenge in urban planning. When collecting data, whether to determine the existing situation or to plan future projects, topography plays a fundamental role. Not only is a large amount of information required but is also often difficult to access the locations, which makes capturing information much more complex than in the case of classical topography. Photogrammetry is the ideal methodology in such areas, and the unmanned aerial vehicle (UAV) is a perfect tool for this type of aerial survey. Read on for details of this project in Uruguay. (By Patricio Birriel... (read more)

Fulfilling the Land Surveyor’s Wants and Needs

Marlyn: the Go-anywhere Mapping Solution Made by Surveyors, for Surveyors
Geospatial information gathered by unmanned aerial vehicles/systems (UAVs/UASs or ‘drones’) is now the driver for business success across many industries and applications. To develop the right tool for this data collection, Atmos UAV had a different approach compared to other commercial drone manufacturers. Rather than focusing just on the product itself, the team was mostly interested in the product fit. After conducting more than 500 interviews with end users, company owners and project managers during the last six years, the company developed Marlyn, a mapping and land surveying solution that meets the industry’s wants and needs.    The necessity of...
