Introduction The Bandra-Worli Sea Link (BWSL) is a civil engineering marvel spanning an arc of the Mumbai coastline. With its cable-stayed towers soaring gracefully skywards, the sea link is a reflection of the modern infrastructure that Mumbai is adding in its progress towards becoming a world-class city…

Many of the world’s volcanoes that erupt, experience significant preeruption surface deformation. Internal magma pressure makes the surface bulge upwards and outwards. Thus, precise monitoring of surface deformation has the potential to contribute significantly to the realisation of a predictive capability of volcanic eruption. In particular, eruption source depth and evolution time can be estimated from surface deformation…

ll countries have to deal with the management of land. They have to deal with the four functions of land tenure, land value, land use, and land development in some way or another.

National capacity may be advanced and combine the activities in one conceptual framework supported by sophisticated ICT models. More likely, capacity will involve very fragmented and basically analogue approaches…

Landslide is a common hazard in the hilly regions which causes heavy losses to life and properties every year. Since 1980 various researches and analyses have been carried out in the GIS environment to identify factors responsible for causing landslides. The important conditioning factors identified by the researchers are slope, geological, geomorphologic structures and land use coupled with triggering factors like rainfall and a few of the anthropogenic activities…

E-Government (or Electronic Government) is described in Wiki as the use of information and communication technology to provide and improve government services, transactions and interactions with citizens, businesses, and other arms of government…

Positioning by GPS can be derived today with a precision of a few millimeters. A GPS receiver determines the distance between the electrical phase center of its antenna and the phase center of a GPS satellite’s transmitting antenna as a pseudorange or a carrier phase observation. It is well known that the phase center of the antenna is not a stable point.

Does Google have multiple standards?

The Pentagon has banned Google from taking photographs and video footage of US military bases after images showing important security features of a base in Texas appeared on the company’s website.

Over the past 100 years the world’s total population has quadrupled – from 1.6 billion to 6.6 billion. (Footnote: Population Bulletin, “World Population Highlights: Key Findings From PRB’s 2007 World Population Data Sheet” http:// www.prb.org/Articles/2007/623WorldPop. aspx.) In many parts of the world we see growing poverty. We now face increasingly worrisome resource constraints and environmental difficulties…

According to a report by ABI Research, there will be over 240 million GPS-enabled mobile phones in 2008. Many of these phones will find their way into India, which translates into a huge opportunity for the Indian GPS/ GIS industry. But will these millions of GPS enabled handhelds be used for navigation alone? The probability is low…
