SPOTMaps is a resounding success
SPOTMaps are mosaics made from SPOT 5 satellite images where features as small as 2.5 metres can be resolved, equivalent to a mapscale of 1:10 000. Coverages are seamless and uniform over the territory of a country or even several countries. SPOTMaps are used as georeferenced basemaps to view an entire territory, simulate new infrastructure planning, perform impact studies, produce or update zoning plans and map.
3D Laser Mapping system to predict avalanches in India
Laser mapping technology is being employed to predict avalanches in the Himalayas. The Snow and Avalanche Study Establishment (SASE) is now using SiteMonitor technology to monitor the snow cover build up, as well as access its displacement with passage of time, and provide valuable inputs for improving the accuracy of avalanche prediction in the Himalayas.
India’s RISAT-1 launch next year
India to launch RISAT-1 early next year. The satellite’s all weather capability to take images of the earth could also be used to keep an eye on the country’s borders round-the-clock and to help in anti-terrorist and anti-infiltration operations. The Synthetic Aperture Radar (SAR), being developed indigenously by ISRO, has the capability to take pictures of the earth 24 hours-a-day, through rain and cloud, thus boosting the country’s disaster response capabilities.

GeoEye finalizes contract for GeoEye-2
GeoEye Imagery Collection Systems, a wholly-owned subsidiary of GeoEye has signed a procurement contract with Lockheed Martin Space Systems Company to complete the development and construction of the GeoEye-2 satellite and the associated command and control.
Milan Cathedral restoration goes hi-tech
A highly accurate, 3D model is to support restoration work at the Milan Cathedral in Italy. Millions of laser-scanned measurements were combined with other survey data and photogrammetric images allowing researchers from the Politecnico di Milano to generate both 2D and 3D visualisations, classical plans and elevations, as well as computer-generated animations. The main aim of the project was to obtain an understanding of the state of the spire in order to support restoration operations.
ESA helps Indonesia
Java’s Mt Merapi in Indonesia has been spewing volcanic ash clouds into the air to deal with this situation, European Space Agency (ESA) is sending email alerts about sulphur dioxide in near-real time. A map around the location of the sulphur dioxide peak is put on a dedicated web page. This Support to Aviation Control Service is based on data from ESA’s Envisat, Eumetsat’s MetOp and NASA’s Aura satellites. ESA started the ‘Support to Aviation for Volcanic Ash Avoidance’ project as a demonstration that uses satellite data and wind measurements to compute the injection heights of volcanic emissions.
