Geospatial industry poised for growth
Information systems alone, based on maps and satellite imagery is set to touch Rs 576 crore by 2010. At present, the market estimates for these services are Rs 12 crore. The optimism is based on the current growth rates of around 200 per cent and the huge potential. Geospatial Today and Spatial India, geospatial publications in association with Antrix Corporation and Survey of India, have brought out the report. According to the highlights of the report, the domestic market estimates for these geospatial services amounted to about Rs 562 crore in the financial year 2005. The market for these services is expected to grow at a CAGR of 17.57 per cent per annum and reach Rs 1,824.98 crore by year 2010. The key driver for this increased growth is the expected investments in land information systems (ILIS) in several states of the country. It also provides an optimistic overview in as much as the total market in our country (domestic and exports markets) is expected to record a potential growth from Rs 962 crore in the year 2005 to Rs 2,820.30 crore at a CAGR of 14.5 per cent. India has emerged as a major data conversion centre for geospatial services. In FY 2005, this sector marked Rs 720 crore with an expected growth rate of 20 per cent.

Apr 2006 | Comments Off on Optimizing gravimetric geoid solution

Transformation of GPS derived ellipsoidal height to orthometric height is one of the most important applications of gravimetric geoid. Its applicability remains questionable if the above transformation cannot be done to a reasonable order of accuracy. Use of GPS observations at levelling benchmarks and subsequently determined geoidal seperation using the geometrical relationship between geoid and ellipsoid (see fig. 1 )…

Modern technologies should appropriately be blended with government developmental programmes.India is an agrarian country with about 72 per cent (about 80 Crores) of its population in about 5,75,936 villages, the villages are inhibited by the rural poor with agriculture as their predominant occupation.They are largely small and marginal farmers, agricultural labourers, artisansand scheduled castes and scheduled tribes. A large number of rural people (about 30 crore) are still living below the poverty line and often face thebasic problem of survival, viz., jobs, poverty, hunger, shelter, ill-health and disease.

Forest cover change in Andaman and Nicobar islands
The damage from last December’s tsunami has been counted in the Andaman and Nicobar islands and it is huge. The islands’ forest cover has taken a big hit, marine life has been badly affected and some famous beaches have vanished. India’s Ministry of Environment and Forests report says the tsunami has badly devastated the islands’ ecosystem. Conducted post-tsunami by ISRO through satellite mapping and released recently, the study found forest depletion of up to 27 per cent in islands like Nancowry and Trinkat. In the Nicobar group of islands, 12,224 hectares of forest cover was lost. Comorta, Nancowry and Katchal saw major coral reef erosion. The report says in some places the entire coral reef area suffered. Satellite images showed that the mangrove trees facing the waves were the worst hit. Extensive areas have turned barren or have been totally eroded in the tsunami’s wake. Some major beaches — big tourist attractions — have almost disappeared. The Noncowry and Trinkat beaches in the Nicobar group of islands have vanished. What remains are just barren rocks. Offi cials say it will take years for new beaches to be carved out from the sea. Marine life, too, has been hit hard. The nesting beaches in the Nicobar group of islands have almost vanished as the islands have gone under the sea by one to three metres.

Hurricane Katrina and its aftermath
Hurricane Katrina severely pounded the Gulf Coast of U.S. with great force at daybreak on the 29th of August. Arriving with 145 mile an hour wind speed, the storm left more than a million people in three U.S. states without power and submerged highways. Hurricane Katrina, formed in the Bahamas in mid-August and struck South Florida on 25 August, killing nine people and leaving a million more without electricity. European Space Agency’s multisensor Envisat satellite has gathered a unique view of Hurricane Katrina in the Gulf of Mexico. Envisat simultaneously acquired these images at 1550 UTC (1150 US Eastern Daylight Saving Time) on 28 August, with its Medium Resolution Imaging Spectrometer (MERIS) and Advanced Synthetic Aperture Radar (ASAR). While an optical image shows characteristic spiralling cloud patterns, a simultaneous radar observation pierces through the clouds to show how Katrina’s 250- kilometre-an-hour winds scour the sea surface. www.sciencedaily.com
