Big Data, Rising Tides

How Advances in Free Remote Sensing Technology Can Help Cities to Prepare for Climate Change
In view of the increased vulnerability of cities to climate and disaster risks, accurate and up-to-date geospatial data is fundamental for a more resilient urban planning approach. Publicly available geospatial datasets are increasingly becoming the foundation stone for more informed urban planning decision-making and better investment prioritization. Today, satellite data can help cities to better prepare for natural disasters such as urban flooding and make more informed investment decisions. For many residents of Kampala, the capital of Uganda, the start of rainy season brings a sense of apprehension nowadays. Originally built on seven hills surrounded by wetlands, the city’s rapid...

Updating the Cadastre in Ecuador

Using Photogrammetry and Lidar Data
The integration of photogrammetry and Lidar can generate synergies and economic savings. The two techniques were used together to detect irrigation and drainage canals for a project aiming to improve irrigation methods and create the related land registry in the province of El Oro in Ecuador. For over 60 years, the decentralised provincial government in El Oro, Ecuador, has been committed to the agro-productive development of the province. As part of this, it has promoted the construction, management and maintenance of a network of irrigation and drainage canals, thus supporting investments in the agro-productive sectors. To improve the efficiency of... (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)

Medical Mapping

Importance of Coordinates and Geo-referencing
The great strength of geomatics is that it enables us to place earth-related object data, geodata, within a spatial context. Maps and GIS are becoming increasingly important in properly planning, managing and monitoring public health programmes. Starting with John Snow's famous cholera map, we discuss the importance of coordinates and geo-referencing in medical mapping. Suppose the government of some country wants to register data on all the buildings erected in its territory. Registration is aimed not only at property-tax collection but also at granting building permits, distributing petrol-station licences and many more tasks of good governance. A government officer with... (read more)

Gearing up for Karlsruhe

GIM international interviews Karl-Friedrich Thöne
From 22nd to 24th September the technology region of Karlsruhe in Germany will draw international geo-professionals from around the world to Intergeo 2009. Experts from five continents will be visiting this, the world's top event for geodesy, geoinformation and land management. Incorporating a trade fair and conference, Intergeo enables participants to meet decision-makers, developers and buyers, and to learn more about the latest topics, trends and technologies in the industry, many focused on the preservation of our planet. We spoke to Dr Karl-Friedrich Thöne, president of the German Association of Surveying - Society for Geodesy, Geoinformation and Land Management (DVW),... (read more)

Multi-sensor Cave Detection in Bulgaria

Meeting the Challenges of Complex Karst Environments
Caves are important in a wide variety of fields, ranging from construction engineering to mineral exploration and archaeology. Despite the scientific importance of caves, geologists believe that only a relatively small number of them have been discovered so far. Exploration is currently mainly conducted by speleologists but this is a time-consuming activity and is limited to exploration based on existing surface openings. A recent project in Bulgaria has shown that the combination of multiple geophysical techniques provides an easier and effective on-surface exploration method that meets the challenges of complex karst environments. (By Tanya Slavova and Atanas Rusev, Bulgaria) Several... (read more)

Digital Norway

Co-operating to Up Geo-information Use
Digital Norway is a collaboration that is playing an important role in implementation of the national spatial data infrastructure in Norway. At the root of the infrastructure is a national geoPortal enabling access to geoinformation data and services owned by producers at national, regional and local level. A sophisticated internet application has been developed to facilitate regional access for a broad range of new GIS users. Technological development is today moving rapidly from desktop GIS towards distributed GIS, leading to increased use and new users and allowing realisation of the full potential for geo-information. Recognising these areas of potential growth... (read more)

Making Sense of Endless Data Flow

GIM International Interviews Xavier Lopez
With a pretty well endless flow of spatial data out there, the possibilities for urban planning, security, map production and other applications are equally infinite. Xavier Lopez is director of product management at Oracle Spatial, a spatial-database management platform that supports all geospatial data types and models. As leader of the group's efforts to incorporate spatial and semantic technologies across Oracle's database technologies, Lopez shares with GIM International some of the latest developments in geospatial data management and provides some insight into what lies ahead for the sector. What are your responsibilities and what do you consider your successes?I've been... (read more)

Use of GIS in Smart City Projects

Managing and Visualising Geospatial Data in a User-friendly Environment
The smart city concept is developing very quickly around the world, because it provides a comprehensive digital environment that improves the efficiency and security of urban systems and reinforces the involvement of citizens in urban development. This concept is based on the use of geospatial data concerning the urban built environment, the natural environment and urban services. The successful implementation of a smart city project requires the development of a digital system that can manage and visualise the geospatial data in a user-friendly environment. The geographic information system (GIS) offers advanced and user-friendly capabilities for smart city projects. This article... (read more)

ISPRS on Track for Melbourne

GIM International Interviews Orhan Altan
Orhan Altan is president of ISPRS. He gives us a sneak preview of the four-yearly ISPRS Congress which will be held in Melbourne, Australia, this summer. Seeing the potential for tremendous developments in the sector in the years ahead, Altan calls on governments to resist cutting back on sciences such as photogrammetry and remote sensing which, while still developing, are already very important. Back in 2009, you said that ISPRS should prioritise environmental monitoring and sustainable development. Is that still your standpoint?Yes – it is still my standpoint and also that of the ISPRS. In 2008, we established several working... (read more)
