Community Risk Mapping

Involving the local community is one of the best approaches for prevention and/or mitigation of disaster, and might even include activities such as geo-data collection, map generation, action-plan development and data maintenance. Mapping enables a community to recognise its own resources and capacities, important in changing the “victim and survivor” mindset in relation to hazard; the idea that one must wait passively for rescuers and relief workers to bring help. In the battle against disaster the individual must be shown how the community can act to avoid it; he must be persuaded to participate. Since the 1990s community-based disaster-risk management...

Mapping Mount Erciyes

Back in 2008, when I was doing my degree in European Studies, I spent almost six months as an intern in Turkey. I still cherish many great memories of my time in that lively and dynamic country at the intersection of Europe and the Middle East. I experienced the famous Turkish hospitality first-hand, I drank countless cups of tea and I learned a lot about the culture and the customs of the people. While I was there, I seized the opportunity to travel and explore as much as possible of the captivating country. I recall how I loved the fascinating... (read more)

International Lidar Mapping Forum

Rapidly Increasing Acquisition Capabilities
With over 580 registered delegates from 32 countries, forty international exhibitors and nearly a hundred abstracts submitted, the eighth annual International Lidar Mapping Forum(ILMF) reflected the growing importance of Lidar and was one of the most rewarding ILMF events ever.<P> Lidar manufacturers, service providers and users, including national and state government departments, presented a total of 34 technical papers. Jamie Wilder of Sanborn Map discussed trends in miniaturisation and software-controlled sensors, and recognised the need to establish national standards and control systems for metadata. He also considered threats posed by lower commercial rates and competition from other technologies such as... (read more)

Satellite Mapping in Bhutan

High-Resolution Imagery in Generating Spacial Information
High-resolution satellite imagery (HRSI) has significant potential for producing 3D spatial information products. Nowhere is this more apparent than in remote areas of the world such as the small Himalayan Kingdom of Bhutan. A project was designed to both demonstrate the utility of HRSI for medium-scale map production, and to pass these technological skills and tools to the Bhutanese. The authors show the potential shown by HRSI in meeting the spatial information needs of a developing country.<P> To support national development initiatives, Bhutan needs more comprehensive topographic and cadastral mapping. In many fields, ranging from environmental management to land and... (read more)

Mapping Urban Fringes

Object Based Image Analysis: a Promising Technique
What is the potential of object-based image analysis (OBIA) for creating land-cover maps from high-resolution satellite images of urban fringes, and can the accuracy of OBIA be compared to visual interpretation? The authors demonstrate that classification of objects rather than individual pixels provides a fast, efficient and simple semi-automatic method for generating land-cover maps. Overall accuracy is equivalent to visual interpretation. Suburban fringe areas are characterised by intermingling of vegetation and structural elements. They are also subject to rapid changes in land-cover. Sustainable development of such heterogeneous, complex and dynamic landscapes requires constant monitoring based on proper decision making and...

New Web Mapping Product

Cadcorp, UK, has unveiled during AGI GeoCommunity 2011 an addition to the Cadcorp Spatial Information System (SIS) product family: Web Map Layers. This is an off-the-shelf but extensible web mapping product designed for map viewing and interrogation. The product is perfect for users without direct experience of GIS, such as members of the public, and the vast majority of office workers who interact with spatial data but lay no claim to be GIS specialists. Web Map Layers  manages spatial data as  individual map layers, each of which is served as an Open Geospatial Consortium (OGC) Web Map Service (WMS). The... (read more)

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)

Mangrove Mapping and Monitoring

RS and GIS in Conservation and Management Planning
The mangroves of the Sunderban area in India are one of the most productive and diverse ecosystems in the world, and yet they are a threatened habitat. To formulate a conservation and management plan periodic mapping and monitoring of mangroves is a prime requisite. The authors demonstrate that remote sensing and GIS techniques, including visual interpretation, are effective and efficient techniques for this purpose. The objectives of this study are threefold: mangrove mapping and monitoring, database creation and conservation prioritisation. Essential parameters in monitoring mangrove areas are disturbance index and fragmentation level. The disturbance index provides a measure for the... (read more)
