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)

Bringing Geography into Everything

GIM International Interviews Ed Parsons
As Google’s geospatial technologist, Ed Parsons is responsible for evangelising Google’s mission to organise the world’s information using geography. GIM International caught up with this ‘man with a mission’ in Barcelona during one of his countless foreign trips. (By Wim van Wegen, GIM International) You’re the geospatial technologist at Google, responsible for evangelising Google’s mission to organise the world’s information using geography. Can you describe that mission? In many ways it’s quite a unique role since the number of people within Google that are really focused on outside the organisation is quite limited. A key aspect of the role is... (read more)

ESRI User Conference – A Preview

7th to 11th August, San Diego, California, US
The Annual International ESRI User Conference takes place from 7 to 11 August in San Diego, California, US. At the accompanying exhibition many companies from all over the world present products and services, often in close relationship to ESRI products. As may be expected from the location of the conference, most enterprises represented at the exhibition are US or Canada-based. But there will also be organisations from Russia, India, France, Japan and The Netherlands. The promised presence of Topcon, Thales and Leica Geosystems demonstrates the vivid and increas-ingly close coupling of GIS and surveying. This connection is also demonstrated by... (read more)

Paving the Way for Self-driving Cars

The Impressive Contribution of Geomatics to Autonomous Driving
Since Karl Benz was granted a patent for his first internal combustion engine in 1879, the automotive industry has changed substantially. Or has it? The main principle remains the same: cars still have four wheels, a petrol- or diesel-powered engine – electric cars are still underrepresented and so far there are just a few hydrogen cars publicly available in select markets – and they still need to be driven by a human being. However, a major change is just around the corner: self-driving vehicles. And they won’t get far without geomatics technologies, claims Wim van Wegen, content manager of 'GIM International'....

Digital Oblique Aerial Cameras (2)

A Survey of Features and Systems
In recent years, aerial photogrammetry has increasingly been using camera systems which capture nadir and oblique images at the same time. The number of oblique systems on offer in the marketplace for airborne geodata collection is growing steadily – a strong indicator that the technology is rapidly maturing. In this follow-up article, the author highlights oblique systems from Digicam, Dimac, Icaros, VisionMap and Wehrli. (By Mathias Lemmens, Senior Editor of GIM International, The Netherlands) The previous article on digital oblique aerial camera provided a general introduction to oblique aerial imagery and the diverse camera configurations which allow oblique image capture....

How YellowScan is Pioneering in the World of UAVs and Lidar

Crossing the Ocean Marks New Milestone in Company’s Advance
YellowScan is one of the most eye-catching companies in the world of unmanned aerial vehicles (UAVs) and Lidar. From its beginnings as a small start-up created by professional surveyors with the goal to revolutionise the market, YellowScan has since become an established name thanks to a passionate team keen to deliver the best Lidar solutions that enable customers to achieve the best results from their projects. The French company has now decided to broaden its horizons by opening an office in North America. This article provides insight into YellowScan’s continuing journey towards making UAVs and Lidar a mainstream solution for... (read more)

The Surveyors of Our World

A Journey through History
In today’s data-driven society, in which location-based services have become an omnipresent part of everyday life, there is no doubt that surveying is all around us. But did you also know that surveyors have been indispensable to the development of the world since civilization began? In this brief journey through history, John F. Brock provides a surprising and entertaining look at the importance of surveying through the ages, from ancient times up to the modern day.     It is not difficult to conjure up an image of how people in ancient civilizations may have divided up their lands. They certainly... (read more)

Mapping an Oil Pipeline

DEMs and Ortho-imagery for Colombia from Dual-band Side-looking Radar
Adverse weather and terrain conditions meant the Cano-Limon oil pipeline in Colombia had never been accurately mapped until orthorectified images and digital elevation models covering an area of 94,000km2 were created using airborne dual-band interferometric IFSAR simultaneously acquired X and P-band data. The authors report on main aspects of the project. The Cano-Limon oil pipeline extends nearly 780km from the Cano-Limon oilfield in Colombia’s Arauca region along the north-western border with Venezuela to a port in Covenas. When fully operational the pipeline can carry up to 20% of Colombian petroleum production, a major source of national revenue. In collaboration with... (read more)

The Tough Road from 2D Maps to 3D City Models

GIM International Interviews Dr Filip Biljecki
The demand for mapping intensively used parts of the Earth, including roads and cities, is steadily growing. This is because today’s rate of urbanisation requires detailed and up-to-date geodata in its full three dimensions. Such datasets help city managers to prevent a decline in liveability, to limit water, air and noise pollution, and to improve fair taxation and rapid emergency response. Crucial is the abstraction of the 3D real world, a concept known as level of detail (LoD). Since 2012 Dr Filip Biljecki has been investigating how to improve the level of detail (LoD) in 3D city models. For his... (read more)

Digital Aerial Cameras

New Developments
The growing need for geo-data everywhere is driving customers to demand shorter turnaround rates and higher levels of detail. These needs can be met by aerial imagery directly captured in digital format onboard an aircraft. In tandem with the new product survey on Digital Aerial Cameras (see our website), the author here gives an overview of new developments. In my overview published in GIM International April 2008, I categorised the various digital aerial cameras under linear- and area-array solutions: one of many possible groupings for these systems. Another, based on technological criteria, considers dimension (size, weight and number of pixels... (read more)
