UAS-supported Agriculture: Still for Innovators

Greatest Potential on Small Farms
While unmanned aerial systems offer huge possibilities in modern farming, most of them lie in the future. These airborne vehicles currently mainly deliver images that are subsequently combined with other input in the farm-specific management system. In the future they will be able to contribute to land management and individual crop-product delivery based on real-time analysis. Another very promising segment for UAS-supported precision agriculture is water management. Precision agriculture is a relatively young concept, dating from around the turn of this century. The first products were focused on add-on guiding systems for tractors. These give a good return on investment,... (read more)

Geo-ethics Requires Prudence with Private Data

GIM International interviews Professor Yola Georgiadou
In today’s datafying world, we continuously leave – unintentionally – digital traces of our daily lives. These traces can reveal a lot about us, our beliefs and our actions to parties who are not the intended recipients of such information. In May this year, Professor Yola Georgiadou held a compelling keynote speech during the FIG Working Week in Helsinki. She called for prudent use of data acquired during the rapid land surveying of developing countries and for action to protect citizens’ privacy. 'GIM International' talked to her about the topic that has become so dear to her: ‘geo-ethics’. What actually is... (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)

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...

MAPS

From mid-March until the beginning of June 2008 one of the galleries of the Walters Art Museum in Baltimore, US, was filled with over a hundred maps, globes and artefacts spanning all centuries and covering all cultures. Exhibits ranged from a 3,500-year-old clay map from Mesopotamia to maps of imaginary landscapes created by writers like Tolkien and Faulkner.?<P> The intention of the exhibition was to stretch the public imagination as to the possibilities of mapping. The exhibition also wanted to make the point that maps can be powerful political tools. National Boundaries When back in 1766 the British colon­ists of... (read more)

Recent Developments in Airborne Lidar

Multispectral Laser Scanning, Single-photon Lidar, Hybrid Sensors and UAVs
The arrival of airborne Lidar, also referred to as airborne laser scanning (ALS), has revolutionized area-wide 3D data acquisition of topography, bathymetry, vegetation, buildings and infrastructure. This article presents an overview of the progress made since then in both sensor and aircraft technology. On top of that, it highlights how the ongoing miniaturization has recently enabled the application of Lidar on unmanned aerial vehicles (UAV), resulting in ultra-high-resolution 3D point clouds with centimetre precision. From Single to Multiple Pulses in the Air Current trends include a steady increase of the measurement rate, achievements in full waveform processing, the spread of... (read more)

Navigating the Future of the Geospatial and Geomatics Sectors

Dr Dorota Grejner-Brzezinska is the incoming president of the Institute of Navigation (ION). She also serves as president of the International Association of Geodesy (IAG) Commission 4, Positioning and Applications. GIM International held an in-depth conversation with Grejner-Brzezinska on the role of the ION, the latest developments and trends in GNSS survey solutions, and the future of GNSS. The Institute of Navigation (ION) serves a worldwide community including those interested in air, space, marine, land navigation, and position determination. How has the Institute evolved? The Institute of Navigation was founded in 1945 by a group of practising air navigators, originating... (read more)

Optimistic Outlook for Galileo

This month we bring you an extended interview with engineer Pedro Pedreira, executive director of the European Global Navigation Satellite System Supervisory Authority (GSA)since July 2005, the body charged with managing the development phase of the much-troubled European Satellite navigation system Galileo. Our wide-ranging discussion with Pedreira appears on these pages accompanied by detailed background information (boxed text). Despite the spiralling costs of Galileo, its anticipated economic benefits, in terms of revenue, employment and expanding markets, are many. Galileo is being funded by the EU taxpayer, so it is important that these benefits be realised. Please introduce yourself and tell... (read more)

Secure Land Tenure Key

GIM International Interviews Dr Anna Tibaijuka, UN Under-Secretary-General and Executive Director, UN-Habitat
On 29th June 2007 UN under-secretary-general and executive director of UN-Habitat Dr Anna Tibaijuka and ITC Rector Prof. Martien Molenaar signed a co-operation agreement to cluster their knowledge on urban development in developing countries: capacity development, training and research. Professor Molenaar feels the Netherlands must raise its profile as expert in urban development and management, as it is already doing with water and agricultural expertise. We asked Dr Tibaijuka how the new agreement would help meet UN-Habitat aims in combating poverty and achieving sustainable urban development. What were the main reasons behind UN-Habitat signing a co-operation agreement with the International... (read more)
