Web-enabled GIS in Disaster Management

A Disaster Hazard and Vulnerability Atlas for SA
Increasingly frequent disasters with attendant damage have heightened climate change related environmental and social vulnerability, emphasising the need for tools to support disaster management. In South Africa a National Disaster Hazard and Vulnerability Atlas has been developed using Web-enabled GIS as the primary user interface. The disaster, hazard and vulnerability ‘Atlas’ which is operational today in South Africa is a virtual book consisting of various chapters, such as drought, flood, cyclones, storms, severe weather, and fires. The Atlas enables users: to search and select data, images, maps and graphs to perform calculations to run models on the fly to copy-paste... (read more)

A New Age (II)

GIM International Interviews David Schell, Chairman and CEO, Open Geospatial Consortium
Our interview with David Shell on the background to, benefits and consequences of Microsoft Corporation joining OGC as a Principal Member provided so many interesting points that we decided to publish the interview in two parts. The first, which focused on Microsoft Corporation membership of OGC, was published in our January 2008 issue, together with an outline of OGC and introduction to David Schell. This final part focuses on topics including benefits of standards implementation, public/private partnership and views on the planet and the future. View Part I  What are the benefits for National Mapping Agencies of adopting OGC standards?... (read more)

Game-based Crowdsourcing for Image Analysis

A Novel Approach to Increasing Analysis and Mapping Capacity
Complex image analysis is a task at which humans are still far better than computers. While computers can conduct simple analysis, they are not yet effective at reliable feature identification and classification, such as to identify where illegal logging is occurring for example. A huge amount of spatial imagery is available nowadays, both of the Earth and other planets, but – in view of the large number of possibilities and the sheer volume of data – there are not enough experts to analyse it all. A novel approach has now been developed that can increase image analysis and mapping capacity founded... (read more)

Pictometry: Long-term Impact on GI Market

GIM Interviews Arne Saugstad and Nils A. Karbø, Blom Group
In September 2005 Blom Group consolidated its already firm position on the Geographical Information (GI) market within Europe by entering into an exclusive licencing agreement with US-based Pictometry for 23 European countries. Pictometry is a new technology for the collection and processing of oblique and vertical aerial photographs. Within a rapidly evolving GI market, the interviewees have a strong ambition to play a major role in driving change. What is your mission and what are your main products and services? Our business model is the collecting, processing and selling of high-quality GI. The demand for advanced, flexible GIS is growing... (read more)

Statutory versus Customary II

Institutional Weaknesses in Nepal
Of the roughly thirty million people living in Nepal, a majority belongs to peasant households and lives below the international poverty line of $1.25 a day. The peasant population has also, under former customary land tenure arrangements, been exploited and pauperised. Land related statutory acts introduced since 1951 have not brought security of rights for the actual cultivators of the land, and thus discourage investment in it. Thanks in part to institutional weaknesses, land administration services are today distrusted by the population. The author inventories these weaknesses and provides suggestions for solution. For many centuries farming has been the principle... (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)

Geoprofessionals Should Look Ouside Their Own Box

Jantien Stoter Bridges The Gaps
Having specialised in 3D GIS, Jantien Stoter has already taken her next leap and is now studying the concept of 5D GIS. Meanwhile, she realises that there are still some gaps to bridge between technical sciences and practice. A highly technical person herself, she shares her views on which directions geoinformation professionals should be looking in to keep the field alive. She recently finished the first phase of a pilot on a 3D standard for The Netherlands' spatial data infrastructure involving nearly 70 stakeholders. The second phase is currently examining how to put the results of the first phase into... (read more)

The Conference Venue: University of Twente Campus

The ISPRS Geospatial Week 2019 will be held on the University of Twente campus. The University of Twente (UT) is the only university in the Netherlands with a genuine campus. It is set in extensive parkland that houses buildings for education and research, facilities for sports and culture, student and staff accommodation and a shopping centre. The ISPRS Geospatial Week will take place in some of the buildings on the so-called ‘O&O plein’ (‘Education & Research Square’), such as the Hal B/Waaier and Carré buildings. The buildings on the O&O plein are located close together, connected by pedestrian walkways. In... (read more)

Sensing Change underneath Vegetation

BradarSAR – A New Approach for Mapping and Change Detection
Already established as a cartographic mapping system, high-resolution X- and P-band airborne radar interferometry and imagery overcome several optical imagery limitations. Today, they provide valuable inputs for recurrent landscape monitoring through change detection algorithms that are able to detect, among other things, deforestation, illegal settlements and soil erosion, to mitigate environmental impacts from hydropower reservoirs and to monitor third-party interference in pipelines. An innovative X- and P-band radar, the BradarSAR, which is deployable on aircrafts with hatches already certified for cameras, promises to make this technology accessible worldwide. By Julianno Sambatti and Dieter Lübeck, Bradar, Brazil Mapping the landscape has... (read more)

Highest Ever Resolution

A Delta 2 rocket carrying the GeoEye-1 satellite lifted off on Saturday 6th September 2008 at 11.50am from Vandenberg Air Force Base, California. Weighing 1,955kg, the satellite can capture every piece of the Earth up to every two days at approximately 10.30am local time. This interview presents further details and strategic considerations.<P>   Sixth September 2008 must have been a very exciting day - what were your feelings on reaching this milestone? GeoEye first made history in September 1999 with the launch of its sub-metre resolution Ikonos satellite, then the highest-resolution commercial earth-imaging satellite. This title now goes to GeoEye-1.... (read more)
