Today and Tomorrow

4th International Conference and Exhibition Laser Scanning and Digital Aerial Photography
The 4th International Conference and Exhibition Laser Scanning and Digital Aerial Photography was recently successfully held with the theme of ‘Today and Tomorrow’. More than 170 participants from twelve countries attended the event in Moscow from 9th to 10th December, and over 40 presentations were given. This conference enables specialists to share practical results of the use of aerial photography and laser scanning techniques, to establish new contacts among users, manufacturers and geodesy engineers and to announce innovations. One of the organisers of the event, Mr Gritskov from the Federal Ecological, Technological and Atomic Supervision Service drew attention to the... (read more)

OGC RSI for Context

The Open Geospatial Consortium (OGC) (MA, USA) has published a Request for Information (RFI) to solicit input on technologies related to Contextual State Descriptions (CSD). A CSD describes the context in which a service chain is executed. CSD is a potential new element of Sensor Web Enablement (SWE); it also is relevant for chaining various image-processing services and other services for geospatial processing in web-services environments. The objective of this RFI is to identify existing capabilities that can provide a robust metadata foundation for supporting agile, adaptive, autonomous processes capable of producing repeatable, predictable results with no intervention. Organisations with... (read more)

RADARSAT-2 To Be Launched in 2005

Features and Applications of Canada’s Second SAR Satellite
RADARSAT-2, Canada’s second Synthetic Aperture Radar (SAR) Earth observation satellite will offer users imaging flexibility and increased data information content, ensuring continuity of all existing RADARSAT-1 beam modes along with powerful new capabilities, from 3m resolution to flexibility in selection of polarisation. The satellite is due to be launched from Vandenberg Air Force Base in California in 2005. RADARSAT-2 is Canada’s next-generation commercial Earth observation Synthetic Aperture Radar (SAR) satellite, the follow-on to RADARSAT-1, launched in 1995. The new satellite has been designed with significant and powerful technical advancements and provides the fulcrum of a programme representing a unique partnership... (read more)

Ukraine in on Galileo

The European Commission has received the go-ahead to open negotiations with Ukraine on a 'co-operation agreement' relating to the development of Galileo, Europe's satellite navigation system. The agreement would comprise multilateral and industrial co-operation, research and scientific activities (particularly relating to standardisation), regional integrity monitoring and financial investment in Galileo. The EU has already signed agreements with China and Israel, while discussions are underway with India, Russia, Brazil, South Korea, Mexico and Australia. An agreement with the US has also been signed that ensures Galileo's compatibility with the US Global Positioning System. (read more)

Global Standards for Hazard Detection

The US Department of Energy’s Oak Ridge National Laboratory (ORNL) and strategic partners, including the National Oceanic and Atmospheric Administration (NOAA) and the private sector, are designing and developing SensorNet, a comprehensive nation-wide system for real-time detection, identification and assessment of chemical, biological, radiological, nuclear and explosive hazards. SensorNet will deploy a variety of sensors at strategic locations such as cellular communication towers and truck weighing stations, connected by secure and redundant communication channels to local, regional and national operations centres. Automated predictive plume modelling will provide rapid assessment of the direction and impact of toxic airborne releases. The objective,... (read more)

Aerial Mapping by Consumer Camcorders

Aerial Videography: Low-cost, Simple, Fast and Appropriate
Developing countries still have a need for mapping systems that are low-cost, simple to operate by local operators, fast in production and yet meet the needs of the application. A satellite mapping system can be a good choice, but cloud coverage and revisit time often limit its application, especially in tropical areas. The author shows that Aerial Videography (AV) mapping based on a consumer camcorder meets mapping requirements. Camcorders are low-cost, simple to operate and widely available. Compared to traditional metric aerial cameras, camcorders are far less accurate and have smaller fields of view. One of the strengths of AV... (read more)

Galileo Contract for NovAtel

The Canadian Space Agency (CSA) has awarded NovAtel (Canada) a CDN$ 1.6 million (US$ 1.34 million) Space Technology Development Program (STDP) contract to extend an initial proof-of-concept prototype Galileo receiver. Galileo is the European Union GNSS system, expected to be fully operable by 2008 with up to thirty satellites. Funding for this contract will be split 60/40 respectively between the CSA and NovAtel. Under the terms of the contract NovAtel will develop L1/E5A engineering receivers and L1/E5A transmitters for CSA evaluation and possible monitoring of prototype Galileo satellites. The new receiver will be integrated into a modified version of NovAtel's... (read more)

Joint China-Brazil Remote Sensing Satellites

The CBERS Programme, a co-operative Chinese-Brazilian Earth Resources Satellites Programme with versatile cameras, has realised a vast success of the Brazilian data distribution policy that is leveraging research and business in Earth observation. It is expected that in 2005 new ground stations around the world will be receiving CBERS images. Since the launch of the first US Landsat-1, formerly called ERTS (Earth Resources Technology Satellite), back in 1972, the world never stopped to improve on remote sensing technologies and broaden the applications. Landsat-1 opened to the world new opportunities for observing the Earth from a completely new point of view.... (read more)
