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...

Web-mapping Demonstrator

British developer of geographic information systems (GIS) software, Cadcorp, has provided unrestricted access to a hosted demonstration version of its popular web-mapping application, Web Map Layers. Prospective users in public and private sector organisations can now judge for themselves how well the application meets their particular requirements for spatial data sharing, by typing the URL of the demonstrator web site into their web browser. Cadcorp has populated the demonstrator with a number of layers of background mapping including OS OpenData for the whole of England, Scotland and Wales, and OS MasterMap data for the major conurbations. Dummy business data is... (read more)

Mapping Nocturnal Light Pollution

Fusing Hyperspectral Data and Photogrammetric Imagery
Artificial light in urban conglomerates causes nocturnal light pollution. Excessive light radiation is expensive as it wastes energy and not only impacts the environment but may also harm human health. Authorities are showing a growing interest in quantifying the amount of artificial light radiated at ground level in their jurisdiction. A recent project in Spain explored an approach based on fusing simultaneously acquired hyperspectral data and photogrammetric imagery. The resulting luminance maps are accurate and have a high spatial resolution. (By Jordi Corbera, Vicenç Palà and Fernando Pérez-Aragüés, Spain) Nocturnal light pollution is a side effect of industrial civilisation and accounts for... (read more)

Southern Mapping Geospatial Celebrates

Southern Mapping Geospatial (SMG), the black-owned South African arm of Southern Mapping Company celebrates its first anniversary this month. Highlights include the first full-visible near-infra-red (VNIR) and short-wave infra-red (SWIR) airborne hyperspectral campaign ever conducted in South Africa where radiation exposure, Acid Mine Drainage, mine rehabilitation, water quality, hydrocarbon spills and asbestos mineral mapping were assessed on four operational mines.     The Lidar division has completed over twenty local surveys across the power, infrastructure and mining sectors and has seen the addition of Tebogo Senoge, a Lidar analyst with over 3 years of experience in the field. The GIS... (read more)

Mapping the Indoor World

Towards Crowdsourcing Geographic Information about Indoor Spaces
The availability of mobile devices for all has boosted the demand for indoor location-based services such as indoor routing or indoor navigation. Both researchers and companies are trying to adapt well-known outdoor solutions to the requirements of indoor spaces. Crowdsourced geographic information is already a promising new data source for outdoor applications. A logical next step would be to apply this novel paradigm to the indoor world. The authors propose and discuss a new model that extends the scope of Volunteered Geographic Information (VGI) communities – essentially OpenStreetMap – towards indoor spaces. This enables the open collection and usage of... (read more)

Mobile Geological Mapping Software

GAF has released a free trial version of GeoRover, a mobile geological mapping software, developed on the basis of experience gained from real geological mapping field work. The software integrates GPS navigation, GIS functionality and spatial raster data management in one tool. This allows field mapping experts to work smarter and faster - thus enhancing productivity and improving efficiency significantly. In early 2003, GAF AG defined a new method for geological field work with the launch of the first version of its GeoRover software, which was based on a modern digital geological mapping approach. Using the experience gathered in different... (read more)
