7 Ways Cities Benefit from Digital Twins

According to the World Economic Forum, the current 4.2 billion people living in urban areas will increase by 2.5 billion by 2050. This increase means that cities and supporting ecosystems must deliver on housing and infrastructure needs while also addressing quality of life, economic growth, safety and security, and resiliency. Assets are becoming increasingly vulnerable to climate-related forces: rising sea levels, drought, seismic activity and violent storms. Cities seek solutions to help them both minimize chronic stress on current infrastructure and mitigate, respond to and recover from the acute shocks of earthquakes, floods and other catastrophic events.

User-friendly Remote Sensing Data Infrastructure in France

New Services Will Stimulate Market Growth
Over the past decade, Geosud has contributed to successfully mitigating the various obstacles to the operational use of satellite imagery for environmental management and territorial development. Geosud’s role in the project will soon come to an end but the services will continue, embedded in an even better infrastructure: Dinamis. As of next year, Dinamis will provide satellite images of land, sea, air or underground, and even online image processing, for organizations related to the public sector in France. As you approach the Maison de la Télédétection in Montpellier, France, the first sight that greets you is a 5.5m-tall receiving station... (read more)

Geoinformation Software as a Service

From Licensing to Subscription
Accurate geoinformation about urban areas, public buildings or historical sites is in great demand. It has become astonishingly easy to capture these scenes through cameras or laser scanning or to acquire open data from a diversity of sources. Professionals without a surveying background can do the job, but such professionals require reliable, robust, easy-to-use and affordable processing tools. Today, cloud computing can meet that need, enabling users to work with software packages running on remote servers on either a pay-per-use or a subscription basis. This article presents a cloud computing service dedicated to geoinformation software. Storing data in the cloud... (read more)

Sensor Fusion for Precision Agriculture

Low-cost Lidar Camera System without GNSS
Precision agriculture has considerably benefited from the use of unmanned aerial vehicles, often combined with active ranging sensors like Lidar to gather information from underneath the crops, but existing systems are relatively expensive for the farming sector. In this project, researchers in Canada have used an integrated sensor orientation method for the local referencing of Lidar measurements. Their approach is based on loosely coupled, image-aided inertial navigation in which the pose of the camera replaces the GNSS measurements. The result is a low-cost solution that is useful for capturing topographic data of inaccessible areas as well as in GNSS-denied environments.... (read more)

Aerial Survey of the Maldives

The April 2008 issue of GIM International (page 11) summarised a project to map the Maldives as an example of how aerial photogrammetry is today applied for mapping large, complex areas. The authors provide further details of the Maldives project, its biggest achievement being first-time-ever 1:25,000 topographic maps of the entire country and 1:1,000 maps of sixteen islands.<P> Republic of Maldives is a chain of islands in the Indian Ocean, spreading north-south over 868km and covering 90,000km2, 99% of which is water. The land area consists of 1,192 islands populated by 280,000 (2001) people. At the turn of the millennium... (read more)

Underscoring Benefits to Humanity

GIM International interviews Orhan Altan
Professor Orhan Altan, recently appointed president of the ISPRS, the international NGO representing more than a hundred nations and regions across the globe, believes the organisation should prioritise environmental monitoring and sustainable development and so contribute to achieving the Millennium Development Goals. International co-operation, says Altan, for advancement of knowledge, research, development and education in this field, would be boosted by greater publicity for ISPRS scientific achievements and successes and their translation into universally understood language. We asked him about his expectations and dreams as head of one of the most important bodies in the geomatics industry, and the legacy... (read more)

GNSS and Heavy Equipment

Financial Benefits of Telematics and Machine Control
Heavy equipment represents a major capital cost for companies in industries such as construction and agriculture. In recent years Global Navigation Satellite System (GNSS) technology, which uses signals from US Global Positioning System and the Russian Glonass satellite system constellations, has been used to improve fleet efficiency. Many companies may hesitate to invest in the technology because management is unaware of its benefits. Such hesitation has only increased during the current global economic downturn. However, recent evidence has emerged to demonstrate the measurable impact GNSS technology may have on company profits.   Equipment telematics, the wireless exchange of electronic information...

Benchmarking Image-based DSM Generation

The Potential for High-quality Airborne Data Collection
In view of the rapid advancement in photogrammetric technology and software for 3D reconstruction, the European Spatial Data Research Organisation (EuroSDR) initiated a benchmark project on image-based generation of Digital Surface Models (DSM). Such a comparative evaluation provides a platform for software developers to demonstrate the potential of their ongoing work. Furthermore, it can help users like National Mapping and Cadastral Agencies responsible for state-wide generation of high-quality DSMs to understand the applicability of such tools while triggering further developments based on their needs. The comparative results from 10 participants presented here provide comprehensive insight into the landscape of dense matching... (read more)

Low-cost versus High-end Systems for Automated 3D Data Acquisition

Modelling an Early Mediaeval Ring Fort in Germany
Topographic mapping is a standard surveying task and the instrument of choice used to be a total station. The use of terrestrial laser scanning has become popular over the past decade or more, but today there is a much wider choice of methods for the acquisition of a digital surface model (DSM). For the 3D recording of an early mediaeval ring fort, the use of three modern systems was investigated: a portable (kinematic) laser scanning system, a static terrestrial laser scanning system (TLS) and a photogrammetric unmanned aerial system (UAS). The systems were compared to each other based on the... (read more)
