Airborne Lidar in Rainforest

Towards a UAV-based System for Measuring Canopy Height
At the experimental forest site Paracou in French Guiana, a range of data is being collected to enable the short-term dynamics within the tropical rainforest canopy to be better understood and quantified. Airborne laser scanning (ALS) was used to obtain high spatial resolution data of the 3D canopy structure. The data has been utilised to build a canopy height model and provides valuable information about the foliage density. The sensing system can also be mounted on an unmanned aerial vehicle (UAV). The French Guianian project demonstrates proof of concept for the further application of this technique. By Sam Fleming, Prof... (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.

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...
