IGOS Geohazards Workshop

BRGM - French Geological Survey has announced the IGOS Geohazards Workshop which takes place at the BRGM Scientific and technical Centre from 27th-29th June 2005 in Orléans, France. This event will bring together representatives from diverse communities involved in the study and mitigation of geohazards (that is, earthquakes, volcanic eruptions, tsunamis and ground instability) to work collectively toward improved disaster management for the geohazards around the globe. The following communities are expected to be among those represented: research institutions, civil protection authorities, geological surveys, volcano observations, earthquake and ground stability monitoring networks, the service industry and space agencies. One of... (read more)

Geomatica Helps MAP:GAC with Disaster Planning

PCI Geomatics' Geomatica software and training services are helping the Multinational Andean Project: Geoscience for Andean Communities (MAP:GAC) with disaster planning and prediction. The MAP:GAC project was established to provide people in the Andes with updated and integrated geospatial information on natural hazards like earthquakes, landslides, and volcanoes. Geomatica software will be an integral part of this process. Training services provided by PCI Geomatics include automatic DEM extraction, terrain analysis, pansharpening, and orthorectification of air photos and satellite data including, ASTER, QuickBird, and EROS. Training also allows users to monitor and analyse a larger area of land than would otherwise... (read more)

Japanese Forest Monitoring

Volume Estimation and Forest Fire Detection with GIS
Forest fires, illegal logging, rehabilitation of degraded land and watershed management are worldwide problems, monitoring being aided by modern technology including earth observation from space, image processing software, GIS and general IT. The author provides an overview of Japanese initiatives in forest volume estimation and forest fire detection. This article is a translated and modified version of an article earlier published in the July 2004 issue of The Journal of Survey. The sustainable supply of natural, coniferous wood, important for local communities in Japan, requires information on structural forest parameters. However, the Japan Forestry Agency record agency contains such limited... (read more)

The Three Pillars of European GI

The INSPIRE directive is about establishing an infrastructure for spatial information within the Community (INSPIRE). This is appropriate, desirable and in accordance with community principles. The infrastructure will co-ordinate and make interoperable and accessible all spatial data collected at national level by Member States. The aim is to document more effectively and on a scientific basis environment-related decisions and their follow-up, in addition to reports required under certain directives. The GMES programme is to enable decision-makers within Europe to acquire the capacity for global and regional monitoring. The aim is to effectively realise European Union objectives in a wide variety... (read more)

Indian GI Actors Look to Grass-roots

Map India 2005 and ISG Conference
The eighth in the series of annual Map India conferences was organised for the first time this year jointly with the Indian Society of Geomatics (ISG). The event took place in the Taj Palace Conference Centre in New Delhi, India from 7th to 9th February 2005 and attracted 1,300 visitors. The guiding themes were for Map India 2005 ‘Going Back to Basics’ and for the Indian Society of Geomatics (ISG) ‘Geomatics Technologies for Bridging the Digital Divide’. These themes indicate a growing awareness amongst Indian geospatial actors that the results of their labour have to trickle down to poten- tial... (read more)

Cross-discipline Interoperability

Info-Dynamics Research Associates Ltd (I-DRA) are engaged in a number of standards and interoperability activities, including a recently funded INSPIRE-GMES data harmonisation project within the European Union 6th RTD Framework Programme (FP6). Infrastructure for Spatial Information in Europe comprises a set of policy and standards activities promoting creation of a geospatial information infrastructure to assist diverse user communities to collect, share, access and exploit geo-referenced information resources across Europe. The joint EC-ESA (European Space Agency) GMES initiative (Global Monitoring for Environment and Security) focuses on six application fields: land cover, water resources, ocean/marine applications, atmosphere, risk management, and security. The... (read more)

Web-enabled GIS in Disaster Management

A Disaster Hazard and Vulnerability Atlas for SA
Increasingly frequent disasters with attendant damage have heightened climate change related environmental and social vulnerability, emphasising the need for tools to support disaster management. In South Africa a National Disaster Hazard and Vulnerability Atlas has been developed using Web-enabled GIS as the primary user interface. The disaster, hazard and vulnerability ‘Atlas’ which is operational today in South Africa is a virtual book consisting of various chapters, such as drought, flood, cyclones, storms, severe weather, and fires. The Atlas enables users: to search and select data, images, maps and graphs to perform calculations to run models on the fly to copy-paste... (read more)

Petrobras Monitors Its Offshore Oil Exploration Activities with RADARSAT-1

Petrobras, a Brazilian oil company, has extended its contract with RADARSAT International for the use of RADARSAT-1 data and services in support of its environmental program. The one-year extension is worth US$ 570,000. This marks the fourth year that Petrobras has been using RADARSAT-1 data in this program. The environmental program is designed to foster sustainable development in Petrobras' offshore oil exploration and development activities in the Campos, Espirito Santo and Santos Basins. Petrobras takes a proactive approach by using RADARSAT-1 data and services to monitor its offshore facilities (platforms and oil-transporting pipes) for any signs of oil leakage or... (read more)

Mapping Towns from QuickBird Imagery

Sub-metre Resolution and High Positioning Accuracy
QuickBird imagery offers the highest spatial resolution so far available from a commercial satellite. Resolutions as low as 60cm, combined with high positioning accuracy, make it well suited for mapping urban areas. The authors present examples. Key requirements for making an appropriate choice of satellite images are: geometrical resolution availability of multispectral bands specification of multispectral capabilities achievable positioning accuracy revisit rate (varies with latitude but is usually 2-3 days. VHR satellites with steered sensors can revisit the same scene more often but at different viewing angles) area covered by a single frame. Good Accuracy If it is to be... (read more)
