The Revolution of Drone-carried Sensors

GIM International interviews 3D Robotics
The world of professional unmanned aerial vehicles (UAVs or ‘drones’) is changing. It is a matter of ‘survival of the fittest’ in terms of the hardware aspect: UAV manufacturers. The interest is now visibly shifting towards payloads and software to capture, visualise and process the data; UAVs are the apparatus, but it’s the sensors and software that really count. GIM International decided to touch base with a company that serves as a good example of the current transformation, and spoke to Chris Anderson, CEO, and Daniel McKinnon, vice president, from 3D Robotics. Read the interview here. (By Wim van Wegen,... (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...

State of the Art in 3D City Modelling

Six Challenges Facing 3D Data as a Platform
Semantically enriched 3D city models have the potential to be powerful hubs of integrated information for computer-based urban spatial analysis. This article presents the state of the art in 3D city modelling in the context of broader developments such as smart cities and digital twins, and outlines six challenges that must be overcome before 3D data as a platform becomes a reality. (This article is a co-production of seven authors, all of whom are mentioned at the end of the text.) 3D city models, as digital representations of urban areas, can be used to facilitate many applications, such as urban...

Keeping an Eye on the World

GIM International Interviews Adam Keith
Defence and security requirements will continue to drive the commercial Earth-observation data market for the next decade, but growing commercialisation of the industry and the data needs of emerging EO nations and private enterprise will also fuel revenue growth. That’s according to Adam Keith, director of Earth observation at international research and consulting firm Euroconsult. EO manufacturing market value is expected to reach $19.9 billion over the coming decade. At the same time, commercial EO data sales are expected to rise by 15%, reaching an annual $4 billion by 2019. There is real future demand for EO satellite manufacturing, data... (read more)

BIM: A New Model for Surveyors

Important Opportunities and Challenges for Surveyors
Building information modelling (BIM) is one of the most intriguing opportunities for surveyors to come along in years. This model-based approach combines technologies and processes to support the efficient creation and use of information for building construction and operations. Because of its strong ties to spatial information, BIM offers a familiar landscape and rich possibilities for surveyors and other geospatial professionals, according to Ron Bisio, vice president of Trimble Geospatial. The opportunities stem from the growing acceptance of BIM within the surveyor’s traditional client base of engineers, architects and property owners. By gaining an understanding of the key concepts of... (read more)

Harmonising UAS Regulations and Standards

GIM interviews Peter van Blyenburgh, president of UVS International
Many people dream of making a living out of remotely piloted aircraft systems (RPASs), but so far a lack of clear rules and regulations has stood in the way of that dream. However, there is a glimmer of hope on the horizon – especially in Europe – and best practices will spread across the world like an ink blot, according to Peter van Blyenburgh, president of UVS International. His independence from individual companies or governments makes him notoriously frank and he is an outspoken ambassador for the sector on all five continents. Your main concern over the past decade has... (read more)

Light Mobile Collection Tools for Land Administration

Proof of Concept from Colombia
Need for administration of property: estimated 75% of the relations between people and land not documented. There is an urgent need for the administration of property and land use rights worldwide as the basis for social and economic growth. Notwithstanding the enormous investments by governments and international organisations in the development of such systems over the past decades, it is still estimated that, from a global perspective, 75% of the relations between people and their land are not documented. So which methods and techniques can be used to develop land administration systems for all, and within our generation? Light mobile collection tools may offer a solution, as presented in this proof of concept from Colombia. By... (read more)

Point Clouds (2)

Survey of Processing Software
Collecting and processing point clouds has been trending topic in the geospatial sector over the past few years. This article focuses on point cloud processing software aimed at creating DEMs or DSMs and products derived from these. The first article of this diptych, originally published in the June 2014 issue of GIM International, focused on functionalities. This survey starts with the software of Terrasolid, which is based in Helsinki, Finland. It will then focus on three systems listed on the Geo-matching.com website, subsequently continuing with software which operates independently from the particular sensors, to then arrive at proprietary systems. It... (read more)

FIG Working Week 2020 – Distance Matters…

What is the ‘FIG Working Week’? It’s a strange name for a conference, but a name that has become close to a trademark and is significant for the many varied activities that are going on during the – almost – week-long event. Since 1878, when FIG was established and gave surveyors the possibility to meet and network, the yearly FIG Conference has proven to be a unique meeting place for surveyors and geospatial experts around the world. But does it really matter to attend a conference, and to meet? Hanoi, Istanbul, Helsinki, Christchurch, Sofia, Kuala Lumpur, Accra, Rome, Marrakech, Sydney,... (read more)
