Mapping Flood Vulnerability

Deriving Risk Indicators from Open Data
Floods have a high impact in densely populated areas, especially when strategic infrastructure is affected. There are various human and territorial factors that influence an area’s vulnerability to flooding. Intensive agricultural activity and large urbanised areas are examples of such human factors, while the soil’s ability to absorb water is a major territorial factor. A quantification of flood vulnerability can be created by combining numerical indicators for the various factors into a single index number that is easy to interpret for decision-makers. GIS tools can easily be applied to calculate these indicators from various open spatial data sources, offering a... (read more)

Web Mapping APIs

ESRI announces that its Web mapping APIs are available at no cost to users who are building applications for use in internal and noncommercial environments. ArcGIS Web mapping APIs have always been free for licensed ArcGIS Server users. Now government agencies, nongovernmental organisations (NGOs), and educational institutions can take full advantage of these mapping applications built on top of ArcGIS Server without additional costs or licensing.     Private businesses can also deploy these API-based applications internally for free.   ArcGIS Web mapping APIs are part of ESRI's Web infrastructure. Developers will have access to ArcGIS Online map services for... (read more)

Web Mapping for Education

The latest version of the EDINA Digimap service has gone live. The service is a co-operation of Cadcorp and the EDINA National Data Centre. Launched in 2000, the EDINA Digimap service specialises in the delivery of a number of geographical data resources over the Internet to over 150 academic institutions. National digital map data ranging from Ordnance Survey (OS) products to geology, marine and historical maps can be accessed by staff and students free at point of use. Based on Cadcorp's web mapping software GeognoSIS, the service also utilises a number of licences of Map Modeller, Cadcorp's desktop GIS.The new... (read more)

Mapping an Oil Pipeline

DEMs and Ortho-imagery for Colombia from Dual-band Side-looking Radar
Adverse weather and terrain conditions meant the Cano-Limon oil pipeline in Colombia had never been accurately mapped until orthorectified images and digital elevation models covering an area of 94,000km2 were created using airborne dual-band interferometric IFSAR simultaneously acquired X and P-band data. The authors report on main aspects of the project. The Cano-Limon oil pipeline extends nearly 780km from the Cano-Limon oilfield in Colombia’s Arauca region along the north-western border with Venezuela to a port in Covenas. When fully operational the pipeline can carry up to 20% of Colombian petroleum production, a major source of national revenue. In collaboration with... (read more)

China's Digital Mapping Plan

China’s State Bureau of Surveying and Mapping (SBSM) has embarked on Digital China, an ambitious project listed in China's 10th five-year plan that aims to map the entire country digitally. The project aims at decision support for the country's leaders in natural disaster prevention and city planning. The state media reported that the mapping project would also include registration of personal details regarding individuals in over 600 Chinese cities and more than 2,000 counties. The SBSM has already created three digital map series of the country with a level of detail comparable to map scales of 1:4 million, 1:1 million... (read more)

Mapping Africa for Africa

Mapping Africa for Africa (MAFA) is a new initiative intended to accelerate the pace of geo-information activities in Africa and to be a catalyst for promoting the importance of geo-spatial information for decision support in the development of the continent. As a contribution to African renaissance, MAFA is expected to spearhead a plan of action providing the fundamental geo-spatial information/maps for sustainable development in support of projects under the New Partnership for Africa’s Development (NEPAD). MAFA results from the ‘Durban Statement on MAFA’ agreed at the International Cartographic Association conference held in South Africa in 2003. It presents recommendations and... (read more)

Radar Mapping Services Contract

Intermap (USA) has announced a contract award of USD3.6 million from Dewberry & Davis for the third phase expansion of its previously announced airborne radar mapping services project in Alaska. Additional contract funding for this project may occur at future dates. Intermap is using its proprietary Interferometric Synthetic Aperture Radar (IFSAR) technology to collect orthorectified radar imagery and high resolution elevation data for an area of Alaska that has never been mapped to this level of accuracy. The elevation data and imagery collected by Intermap will be used in economic development, infrastructure development and homeland security applications. Due to persistent... (read more)
