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.

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)

ECOLAB 2004 Congress

Remote Sensing and GIS in Amazonian Coastal Ecosystem Study
The ECOLAB 2004 Congress was held in Cayenne, French Guyana, from 30th November to 5th December with the objective of exchanging scientific progress on the management and conservation of Amazonian Coastal Ecosystems. Over a hundred participants from Brazil, French Guyana, Guyana and Venezuela attended and some eighty papers were presented. The ECOLAB initiative started in 1992 and the 2004 Congress was the eighth of its kind. ECOLAB is a research programme based on the partnership of scientific institutions studying Amazonian coastal regions (see Table). The Amazon is the world’s largest river in terms of freshwater and sediments discharge. The river... (read more)

GeoTango Introduces SAME

GeoTango International (Canada) introduced SAME (See Anywhere Map Everywhere), a network-centric system that allows performing 3D visualisation and interactive exploration of multiple data sources over a distributed network. The product uses satellite/aerial images and sensor networks to provide real-time or near-real-time monitoring, surveillance and mapping of areas and structures anywhere in the world. When zooming-in, the system displays images or maps that are more detailed. Hotspots like webcams and other information sensors are accessible directly via a displayed image or map. (read more)

NASA Monitoring System

NASA scientists have developed a regional visualisation and monitoring system for Central America and the southern Mexican states designed to make NASA Earth observations and predictions freely and readily accessible to anyone with an internet connection. The system’s Spanish acronym is SERVIR, which means 'to serve' and it features a Web-based data archive of maps and satellite imagery, decision-support tools and interactive visualisation capabilities. NASA devised the system in partnership with several other organisations, among them the US Agency for International Development, the World Bank and the Central American Commission for Environment and Development. Scientific and technical collaborators include the... (read more)

No Management without Measurement

Towards a GDI Business Model for Africa
GIS specialists in Africa are quickly seeing the horizon with respect to Geospatial Data Infrastructure (GDI); it is the bottom line that is proving elusive. Financial, budgeting and accounting measures need to be brought into the discourse. Accessing and allocating funds are key to identifying a functional business model for GDI and may also provide a mechanism for government co-ordination. Recognition of the need for financial tracking of geospatial investment is not new. In 1934 a six-month intensive review was conducted of 28 federal agencies engaged in surveying and mapping in the United States. This study noted a disturbing proliferation... (read more)

Geospatial Co-operation in Vulnerable Sahel

AGRHYMET: Serving the Sahel Region with Geo-information and Training
To monitor the environmental changes and find solutions in the vulnerable Sahel region, the AGRHYMET institute (AGRiculture, HYdrology and METorology) was established thirty years ago. AGRHYMET aims at collecting, processing and managing biophysical and socio-economic data. Furthermore, the organisation services the Sahelian countries with information and training to cope with challenges in food security, natural resource management and desertification control. The Sahel region is a zone stretching across the African continent from the Cape Verde Islands and Mauritania to Sudan. The region is synonymous with desertification, drought and harsh living conditions. Man-induced changes to vegetation from overgrazing and intensive use... (read more)

Spatial Data Quality: Happy Hunting Ground

Laser-Scan has contributed to the OGC interoperability specification process since 1996, playing a significant role in test-bed programmes and OGC contributions to ISO TC211. Within the context of OGC, Laser-Scan is synonymous with topology and its role in GML. Indeed, the company played a key role in the decision to base GML on XML. These past accomplishments are fine, but I am mindful of the comment in the eSpatial column in these pages a year ago: "It is often difficult, expensive and risky to integrate GIS software with general applications." From a geospatial industry viewpoint I believe we, the industry,... (read more)

Geo-information for Disaster Management

Large-scale 3D Data Needed by Urban Areas
The tsunami in Asia has once again demonstrated that human beings are at risk at any time, anywhere. Disasters in highly populated environments are difficult to manage using only small-scale (1:10,000 to 1:250,000) 2D geo-information. Innovative technologies and working procedures are thus urgently required for the response phase of disaster and emergency management. International attention is drawn to the use of large-scale (1:500 to 1:2,000) 3D geo-information and 3D geo-information technology for disaster management in urban areas. Time constraints, stress, and limited-capacity equipment are among many factors affecting rescue operations. Early warnings may help in evacuation and safety. Good collaboration... (read more)
