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)

Digital Oblique Aerial Cameras (1)

A Survey of Features and Systems
It has become customary for me to provide a survey article on digital aerial cameras in the April issue of GIM International every three years. The previous survey (April 2011; vol. 25:4) addressed small, medium and large-format cameras, while in April 2008 (vol. 22:4) the focus was on sensor architecture. This article and a follow-up one will centre on oblique aerial camera systems, the use of which is steadily growing for (3D) capture of urban areas and roads, railways and other corridors. (By Mathias Lemmens, senior editor GIM International, The Netherlands) After providing an introduction to oblique aerial imagery and... (read more)

Innovation at the Heart of Geospatial Growth Strategy

GIM International Interviews Ray O’Connor
The geospatial industry is involved in an ongoing transformation. From its headquarters in Livermore, California, Topcon Positioning Systems (TPS) manages 31 operations located in 15 countries on five continents, employing more than 2,100 people. Here, we speak to Ray O’Connor, CEO of TPS, on the role his company is playing by providing connectivity with software and precision-measurement hardware for a range of market sectors. What’s TPS’s growth strategy? Topcon has an 82-year history and remains a major player in optical surveying instruments. When I joined the company in 1993, there was a major drive to identify areas for growth, with... (read more)

The Advancing Industry of Geoinformation

Survey of Geomatics Professionals Reveals Valuable Insights
At the start of this year, GIM International conducted a readers’ survey aimed at gaining a clear picture of the current state of the geospatial industry. With more than a thousand replies received, the response was better than expected and resulted in valuable insights: which new technologies hold the most promise? What is the role of UAVs in today’s geospatial industry? Which other market trends are visible? And how do geomatics specialists view the future of their profession? With consideration of various fields of application – such as mining, forestry, agriculture and building & construction – this article takes you on... (read more)

Digital Photogrammetric Workstations

Status and Features
For over a century, images taken from above-ground platforms have been major data sources for topographic mapping, creation of base maps and many other uses. For the past decade or more, data has been extracted from the imagery using computer software on what have become known as digital photogrammetric workstations (for short: DPWs). Some of the tasks can be performed almost fully automatically while others require extensive human involvement. To tie in with the new product survey on digital photogrammetric workstations published on our website, this article discusses the latest status and features. Task photogrammetry The basic task of photogrammetry... (read more)

Lidar’s Next Geospatial Frontier

The State of Lidar for UAS Applications
Over the past two decades, airborne Lidar has evolved from a developmental technology into a well-established mapping solution, and in the process has revolutionised the surveying and mapping industry. Today, unmanned aerial systems (UASs) represent the next geospatial frontier. With recent advancements in sensor technology, the adoption of Lidar for UASs is rapidly expanding, leading to new industry horizons. Read on for insights into the current state of UAS-based Lidar technology and emerging trends. (By Michael Starek and Jinha Jung, Texas A&M University-Corpus Christi, USA) Integration of traditional airborne Lidar mapping technology with UASs has been challenging due to the... (read more)

Data Sharing is Smart – Geo-related Trends in Engineering & Construction

There could be many keywords representing important trends in the capture and use of spatial data in the engineering & construction industry, but 3D, BIM, AR and UAV are definitely high on the list. As this article examines, uniting them all is one major cross-industry challenge: interoperability and data integration in support of much-needed higher workflow efficiency in the whole value chain. The engineering & construction sector has been slower than most to adopt new technologies. While innovation may have occurred on the enterprise level, overall productivity in the market has remained almost flat for 50 years. In fact, labour... (read more)

Towards All-in-one Photogrammetry

A Case Study of Dense Image Matching Using Oblique Imagery
Modern photogrammetric camera architectures provide high-resolution imagery in nadir and oblique views. This case study sets out to prove the potential of oblique imagery to deliver dense point clouds to be used for DEM, 3D city model and true orthophoto generation – an important step towards ‘all-in-one’ photogrammetry. 3D point clouds for DEM or orthophoto production are typically collected using airborne Lidar systems. The recent development of dense image matching methods provides an efficient alternative by deriving point clouds from imagery. Within this fully automated image processing pipeline, corresponding pixels between multiple images are determined. Each pixel represents a sight... (read more)

Preserving the Past Using Geomatics

The Impact of Modern Mapping Technologies for Cultural Heritage
Over the past decades, the tremendous progress in information and communication technologies (ICT) has totally changed the way we live, communicate and indeed measure and model the world around us. Prof Andreas Georgopoulos from the National Technical University of Athens in Greece maintains that this progress has influenced the traditional land surveying profession more than any other in the engineering business. Geomatics and geoinformatics are a consequence of this technological advancement, and today’s professionals should feel privileged to have experienced this radical change first-hand. But how has the progress influenced specific parts of the profession and related applications such as the... (read more)

Kadaster: Ambitions and Goals

Leading Role for Key Registers
Programmes at European and national government level are signalling opportunities, setting policies and taking measures to capture the benefits of ICT. In tandem with societal demands, this will lead to government services via internet, key registers, web services and more. The author sketches the ambitions and goals of the Netherlands Cadastre (Kadaster) against a background of European policy, ICT developments and customer expectations. ICT offers many opportunities for improving the performance of government and business. Areas which may profit include education, safety, health care, international co-operation, economic efficiency (integrated value chains, business-process management, reduction in administrative overheads), prevention and detection...
