Intergeo 2007

Knowledge and Action for Planet Earth
2007 marked the thirteenth consecutive annual Intergeo. The venue for this major conference and trade-fair for geodesy, geoinformation and land management, held this year from 24th to 28th September, shifts from year to year, always within the boundaries of Germany. This time the train stopped at Leipzig. The event is organised by HINTE GmbH in association with the German Association of Surveying (DVW), and this year took place in conjunction with the fifty-fifth German Cartographer's Day. The event made clearer than ever that geo-data acquisition is a booming industry. All things considered, including current financial figures, vendors of data acquisition... (read more)

Intergeo 2006 - Preview

10th - 12th October, Munich, Germany
‘Knowledge and Action for the Earth’ is the theme of Intergeo 2006, the annual geodesy and geo-information conference and trade-fair organised in association with the German Association of Surveying (DVW) and taking place from 10th to 12th October. Roaming as it does annually from one major city in Germany to another, Intergeo this year settles in Munich, world-renowned Bavarian capital of science, technology, arts and culture and, last but not least, the October Beer Festivals. Almost fifteen thousand visitors are expected to come together at the Neue Messe Convention Centre, the same number as attended the ESRI International User Conference... (read more)

An App Transforms Land Administration

GIS Is Innovating How Land Data Is Collected and Managed
When Brent Jones – the man who oversees Esri's worldwide strategic planning, business development and marketing activities for land records, land surveying and land administration – started his career as a surveyor, data collection involved hauling around heavy tools such as total stations, tripods and range poles. Data had to be manually recorded in weatherproof field books using a number-four lead mechanical pencil. Then came the advent of the Global Positioning System (GPS), experimental satellites, receivers powered by car batteries and PhD students to help us process that data. However, more recent advances in the field have been exponential. Today's GIS technology... (read more)

Massive High-resolution Digital Content

LizardTech
LizardTech delivers wavelet-based imaging software for managing and distributing massive high-resolution digital content such as aerial photography and satellite imagery and scanned colour documents. Main products include GeoExpress with MrSID Document Express with DjVu and Express Server. LizardTech was founded in 1992 in Santa Fe, New Mexico (hence the reptile in the name and logo) by a few researchers, developers and entrepreneurs working together on wavelet-based imaging at Los Alamos National Laboratory (LANL). The privately owned company moved to Seattle’s historic Pioneer Square district in the late 1990s, where it settled down in a classic century-old building. In 2003 the... (read more)

The Respond Project

Geo-information for Humanitarian Aid
The Respond project is intended to develop into a sustainable humanitarian aid service. By working in concert with other information providers, humanitarian organisations can quickly and easily access maps, satellite images and other useful geo-information. The author discusses Respond’s organisational framework, solutions provided up to now and the role of Infoterra. Geo-information is vital to the day-to-day management and delivery of humanitarian aid, whether in response to rapid-onset natural disasters or more slowly developing and persistent, complex emergencies. The Global Monitoring of Environment and Security (GMES) programme from which Respond springs provides a good opportunity to bring together European capacity... (read more)

Usability Testing Dynamic Maps

Overcoming Limitations of Mobile Devices
Increasing use of geo-information in "smart phones" and PDAs has led to users being disorientated by map displays on small screens, while outdated maps, storage capacity and processing power further inhibit use. High-bandwidth wireless connections resolve some such limitations but map display remains an impediment to wider use. The authors describe research into dynamic presentation of maps at the desired level of detail.<P> A user is forced by the small screen of a mobile device into a great deal of panning and zooming to visually link map features to objects in the environment. Since each zoom or pan usually requires... (read more)

UAVs in the Mining Industry

Capturing the Andalusian Mina de Aguas Teñidas
A growing number of mining companies are employing unmanned aerial vehicles (UAVs). Equipped with digital cameras, such remote-controlled small aircraft generate high-resolution aerial imagery which can be further processed to produce highly precise orthophotos, point clouds and 3D models. Surveyors and engineers can use this data to make statements and forecasts about the development of the mine, document changes as well as calculate volumes of spoil and stockpiles. In mines with both aboveground and underground areas, UAVs can provide important information about the state of the aboveground area, thus improving the safety of the workers underground. This was practised in... (read more)

Unmanned Aerial Systems for Cadastral Applications

Testing a Fit-for-purpose Land Administration Approach in Indonesia
In recent decades, imagery-based methods have gained legitimacy in the domain of cadastral data creation. Contemporary experiences from Rwanda, Ethiopia and Lesotho, along with older activities from Thailand, already demonstrate the potential of conventional aerial imagery and high-resolution satellite imagery. More recently, unmanned aerial systems (UASs) have received increasing interest in the field of land administration. Already documented trials and demonstrations are evident for Albania, Namibia and Rwanda. The exploratory work continues; results from trials undertaken in Indonesia are presented here with a view to identifying the opportunities and challenges for embedding the technologies in a fit-for-purpose way into the...

Using Lidar North of the Arctic Circle

Challenging Aerial Acquisition Mission in Greenland
The acquisition of precise geodata is a high priority in Greenland, the world’s biggest island and a place of great diversity. There, geodata is considered vital to support almost all aspects of community activities and also for the future development of the autonomous territory within the kingdom of Denmark. This article provides insight into an aerial acquisition mission made all the more challenging by Greenland’s unique Arctic location. In the summer of 2019, ASIAQ Greenland Survey commissioned the engineering company Niras to acquire Lidar data and photographic imagery of the five largest cities in Greenland: Nuuk, Sisimiut, Ilulissat, Qaqortoq and...

High Resolution

3D Imagery from Space
The last decade has shown a series of developments triggering intensification of the use of satellite imagery for a multitude of applications. These developments include, among many: reduction in cost of launching satellites into orbit, improvement in revisit time for capturing a scene and boosting ground sample distance to up to 50cm; a spatial resolution that challenges aerial photogrammetry. Among the greatly in demand products derived from satellite data are Digital Elevation Models (DEM). In tandem with the new product survey on Very High Resolution Satellite Imagery (see our website), the author here discusses the possibilities of very high-resolution optical... (read more)
