Downtown Dublin as a Lidar Point Cloud

A Highly Accurate, Diverse and Dense Annotated Laser Scanning Dataset of a City Centre
The advance of Lidar data acquisition technologies is substantially increasing the amount of spatial data obtained and it is becoming cost-prohibitive to process it manually. Artificial intelligence (AI) has now started to offer cost-effective solutions to analyse and utilize those big datasets. AI can be employed for scene understanding, accurately detecting objects and classifying 3D assets. These are the significant fundamentals of several applications including autonomous navigation, intelligent robotics, urban planning, emergency management and even forest monitoring. The most popular types of 3D spatial information for such applications are Lidar and imagery data. This article describes the dense annotated ground-truth... (read more)

The Fierce Rise of Airborne Lidar

A View on Status, Developments and Trends
Today, automatic matching of overlapping aerial imagery and airborne Lidar are the main geodata technologies for capturing dense point clouds of the Earth’s surface. The sampled points are used for the generation of bare ground representations which are often augmented with buildings and trees. Airborne Lidar is flourishing as a prevalent geodata acquisition technology and continues to show a fierce rise in terms of advancements and applications. Read on for an article that discusses the main technological advances of today’s operational systems and surveys the state of the art, developments and trends. Having trained as a geodesist and photogrammetrist, I... (read more)

Geoinformation in Arable Farming

What’s Hot and What’s Not in Precision Agriculture
Agriculture enthusiastically absorbs geospatial technologies. Precision farming practices in particular benefit from location intelligence. The future in agriculture with geospatial applications is bright. Besides more efficiency on the farm, geospatial technologies also offer new business opportunities and new sustainability concepts. But the adoption of geospatial innovations is lagging behind expectations. So what’s hot and what’s not? This article examines the state of the art in geospatial technologies in agriculture and attempts to forecast the trends. By Tamme van der Wal and Henk Janssen, Wageningen University & Research (WUR), The Netherlands By far the most popular geomatics technology among farmers is... (read more)

Potential of Small Satellites

GIM Interviews Dr Rainer Sandau, Chairman, International Academyof Astronautics (IAA)
Small satellites for earth observation are an important ongoing development in space research. How can mapping and disaster management benefit from small-satellite systems? What is the potential and what the challenges? Are small satellites an inferior alternative for developing countries that cannot afford large satellites? This month’s interviewee, Dr Rainer Sandau, provides answers to these and other questions. What are mission, scope and organisational structure of IAA? IAA encourages international scientific co-operation through scientific symposia and meetings and through the work of six commissions dedicated respectively to Space Physical Sciences, Space Life Sciences, Space Technology and System Development, Space System...

Small Company, Big Ambitions

GIM Interviews Paul Bosman, CEO, CycloMedia Technology BV
CycloMedia Technology BV is a privately owned company based in Waardenburg, The Netherlands. The company exploits an in-house developed camera system for capturing urbanised areas from the road. In January 2006 Paul Bosman became CEO. He talked to us about his many ambitious plans. What are the main products and services offered by CycloMedia? Since the early nineties CycloMedia has built up experience in systematic mapping of urbanised areas on the basis of 360-degree images (so-called cycloramas). These images are captured from the road and at street level using a car as carrier of the camera system, including positioning and... (read more)

National Mapping Agency of Belgium

With a history stretching back to 1831, the National Mapping Agency (NMA) of Belgium has always respected the scientific approach. In 2006 it underwent a complete restructuring of work processes to become what it is today, an ultramodern organisation headed for the past five years by Ingrid Vanden Berghe.<P> In Brussels, home of the European Commission, a summit predictably delays road traffic, so that it is with some sense of reward that we arrive at the historical setting of Abbey ter Kameren, where the National Geographic Institute (NGI) is sited, along with the Belgian National Mapping Agency (NMA). From 1831... (read more)

Mobile GIS Systems

Technical and Business Features
Today the computer power of handheld devices is comparable to the desktop computers of a few years back. Together with rapid adoption of the internet, this progress has triggered fitting mobile GIS systems into work processes. Mobile GIS is a means of geo-data collection using GNSS positioning, GIS functionality, wireless connection and mapping, all integrated in one compact device. In tandem with this month’s product survey (page 28), the author gives a detailed outline of the technical and business features of mobile GIS systems. Many work processes start with dispatching digital geo-data from the central GIS to the plotter next... (read more)

Good Governance, Good Geo-info

Essential Role for GI at all Levels
Where just two decades ago spatial data was mainly carried on paper maps, map and three-dimensional topographic data is now accessible via Google Earth. Where accurate positioning was once the professional pride of highly trained geodesists, we now see such services provided by GPS-based consumer products. This revolution in technological developments and demand for information implies the need for continuous upgrading of professionals: ‘lifelong learning’. Lifelong learning is relevant not only for the professionals concerned but also for their organisations. These are in a permanent state of flux in order to adjust to their continually changing envir-onment. This may flow... (read more)
